Since 80 percent of learning is through vision, if a child has a visual problem it will affect their reading comprehension.  

The first step in reading is reading fluency. Once a child has mastered that, they will start to be able to comprehend what it is they are reading.

Without comprehension, reading is a pointless and frustrating exercise. What most people don’t realize is that visual information is essential for reading comprehension.

If a child struggles with reading comprehension it could be due to an undiagnosed vision problem.

A traditional vision exam primarily measures visual acuity, or 20/20 eyesight, unusually it does not assess functional vision, so a child with ’20/20 sight’ could still have a visual problem.

Functional vision is how your entire visual system – the brain, the eyes, the visual pathways – works together to help you interact with your environment.

There are 17 visual skills that impact a child’s school performances.

The functional vision exam includes a comprehensive assessment of the visual skills including;

  • Lazy eye
  • Eye focusing
  • Eye Tracking
  • Binocular function
  • Convergence
  • Visual information processing

A functional eye exam is vital for all children with reading comprehension challenges.

If your child is not reading to their grade level, contact an eye doctor near you, who can diagnose and treat any visual problems.

Vision and reading comprehension

There are in fact 17 visual skills that can impact a child’s school grades. Listed below are just 3 of the top functional vision problems related to reading comprehension:

1. Eye focusing (Accommodative insufficiency)

Accommodation is the eyes’ ability to focus. Tiny muscles inside your eyes contract or relax to change the shape of your eyes’ lenses and allow you to bring objects at different distances into focus.

When you focus on something close, the muscles contract, and when you focus on something in the distance, they relax. This can make reading difficult when trying to maintain focus on objects up close, such as a book.

2. Convergence insufficiency

Convergence insufficiency is a problem with keeping both eyes working together, especially when focusing on words on a page.

When the eyes don’t converge accurately, it can affect the ability to concentrate on simple near tasks. This can also result in headaches, double vision, and visual discomfort when performing near activities like reading.

3. Eye tracking (Irregular saccades)

Eye saccades is a visual skill that enables a person to make quick eye movements from one object to another, such as moving from word to word while reading. Irregular saccades make reading more challenging and difficult for a child to keep their place when reading.

Can vision therapy help?

Vision therapy is a fully personalized treatment program designed to improve and strengthen visual skills, and retrain a child’s visual system to interpret visual input with increased accuracy and ease.

Vision therapy is more than just simple eye exercises — it improves brain-eye communication, and the effective operating of a child’s visual system.

The goal of vision therapy is to boost attention, concentration, learning, and reading.

Overusing eye drops can cause more harm than good.

Do you find yourself constantly reaching for eye drops? While eye drops may provide satisfying and quick relief for itchy or irritated eyes, exceeding the daily recommended dosage can cause serious eye health problems..

How does over-usage of eye drops happen?

Most people over-use eye drops when they view their eye drops as a cure to their condition rather than a temporary treatment.

This may lead to inserting too many drops into the eyes or using the eye drops too frequently throughout the day. If you think you may be overusing your eye drops, contact an eye doctor near you to help diagnose the underlying cause of your symptoms.

Risks of overusing eye drops

When overusing eye drops, you can run the risk of:

  • Masking a more serious problem. Alleviating the symptoms while ignoring their root cause can allow a condition to worsen.
  • Rebounding. The original eye symptoms may return stronger than before as the effects of the eye drops wear off or when the drops are no longer being used.
  • Washing away your natural tears. Artificial tears help with insufficient tear production and feel great as they lubricate the eyes. But overuse can literally wash away natural tears and the natural moisturizers that protect the eyes.

Conditions that eye drops could be masking

Red, itchy eyes are a symptom of several conditions, including:

  • Allergies Allergies to the environment or pets can cause dry, itchy eyes.
  • Blepharitis Red and inflamed eyelids, caused by dry eye, a bacterial or fungal infection, parasites, or gland dysfunction, all of which require treatment beyond over-the-counter eye drops.
  • Dry eye syndrome Redness, itchiness and irritation are common symptoms of dry eye syndrome. In severe cases, DES can damage the cornea.
  • Eye strain Focusing on work all day  can cause eyes to become tired, strained and irritated.
  • Eye trauma Rubbing or scratching the eye can cause blood vessels to break, making the eye red and itchy. More serious traumas will require prescription eye drops or surgery.
  • Foreign objects An eyelash, dust, or something worse could be in the eye. If an individual has long-term issues with dry or itchy dry eyes, they need to make sure a foreign body isn’t the culprit.
  • Pink eye A viral or bacterial eye infection, also called conjunctivitis, can cause swelling, itchiness and burning.

Regardless of why you may be using eye drops, the only way to get to the root cause of your symptoms is by scheduling  an eye exam to receive a complete diagnosis and treatment.

Are your eyes red and irritated? Is it dry eyes or an eye infection?  

To help you out, here are the key differences between dry eyes and eye infections.

Important Note: While learning about these eye problems is helpful, nothing can replace the care and diagnostic skills of an eye doctor.

If you experience any of the symptoms mentioned below, schedule an eye exam with an eye doctor near you.

Dry eyes or eye infection? 

Dry eyes

Dry eyes are caused by a chronic lack of eye hydration, brought on by either poor tear quality or insufficient tears.

Individuals suffering from dry eyes will experience any number of the following symptoms:

  • Blurred vision
  • Burning or itchy eyes
  • Grittiness
  • Red, irritated eyes
  • Sensitivity to light
  • Watery eyes

Dry eyes can be caused by irritants such as heat and air conditioning, dry, windy weather, some health conditions, drugs, the aging process, or too much screen time.

The goal of treating dry eyes is to keep your eyes hydrated, which can often be accomplished by using artificial tears, increasing tear production, treating inflammation in the eyelids, or conserving tears in the eyes.

Eye infections 

Eye infections occur when harmful microorganisms like bacteria, fungus and viruses invade and wreak havoc on the different parts of the eye, such as the conjunctiva and eyelids.

Here are a few common signs:

  • Crustiness around the eyelashes and lids
  • Enlarged lymph nodes near the ear
  • Eye pain or irritation
  • Eye redness
  • Swollen eyelids
  • Yellowy discharge from the eyes

If you suspect that you have an eye infection, don’t take a “wait and see” approach. Prompt treatment will facilitate a speedier recovery and help prevent any possible eye damage.

What to do? 

The key to properly diagnosing and treating any eye condition is a comprehensive eye exam. 

In addition to examining your eyes, your eye doctor may also ask questions about your lifestyle, medical history and family history to better understand your condition.

So, whether you suspect you have dry eye syndrome or an eye infection, schedule an eye exam with an eye doctor near you.

If a child has some kind of visual dysfunction, it can hinder their academic performance and affect their reading fluency.

Children who struggle with reading fluency are often intelligent and bright, but somehow they have difficulty reading.

If your child avoids reading or is not reading to their potential, contact an eye doctor near you, as they may have an undetected visual problem.

What is reading fluency?

Reading fluency is the ability to read quickly, accurately, clearly and with expression. Children must be able to read fluently, whether aloud or quietly to themselves, in order to comprehend what they read. While reading aloud, the words should sound natural, with proper intonation.

Reading fluency is an essential classroom skill as it connects the child’s word recognition to their comprehension. 

Reading fluency gives students the opportunity to concentrate on the meaning of text and to draw correlations between what they are reading and their own prior knowledge. Reading fluency enables students to develop an accurate comprehension.

Non-fluent readers read slowly and sound choppy. They spend more time decoding, so they have less time and energy to understand what they are reading.  Oftentimes, they have to read the same passage many times in order to comprehend it.

Reading fluency and vision

Reading fluency is dependent on the strength of visual skills such as convergence, binocular vision, accommodation, visual fixation and saccades.

A deficiency in any of these crucial visual skills can lead to reading problems, which can have a negative effect on a child’s ability to learn.

Which visual skills are necessary for reading?

  • Convergence – the ability of the eyes to retain a single image by turning inward, while at the same time focusing on a near object, such as a book or computer screen.
  • Binocular fusion – the ability of the brain to create a single image using distinct visual information received from each eye.
  • Accommodation – the ability of the eyes to switch focus between two distances while maintaining clear vision.
  • Visual fixation – the ability of the eyes to accurately focus on a target image, such as a word on a page.
  • Saccades – rapid eye movements across two or more focus points, such as when reading a sentence across a page or moving from one word to the next.

Could my child have a vision problem?

As children may not be able to verbally express themselves it can be difficult to identify a vision problem.

Common signs of a vision problem may include:

  • Covering one eye
  • Behavioral problems
  • Frequent blinking
  • Excessive fidgeting
  • Limited attention span
  • Tilting head to one side
  • School avoidance
  • Reading comprehension difficulties
  • Reading below school grade level
  • Reading avoidance

If your child shows signs of a visual impairment, it is important to visit an eye doctor near you for a comprehensive evaluation of your child’s vision and visual skills.

Can vision therapy help?

Vision is a learned skill that can be trained and strengthened.

If a vision problem is at the root of your child’s reading difficulty, a vision therapy program can improve your child’s reading grades.

A vision therapy program may help to improve your child’s visual skills and provide them with the necessary tools to succeed in learning and reading.

Each vision therapy program is created to the needs of the individual child, and may include prisms, filters, specialized lenses and eye exercises to help retrain the brain-eye connection and improve visual skills.

Over 30% of those diagnosed as having dyslexia have an eye tracking deficit.

When a child has a visual processing or perceptual disorder it hinders their ability to make sense of information taken in through the eyes and visual system. This does not mean they have problems with sharpness of vision or sight.

Many children have difficulties with eye tracking, which impacts how the brain interprets visual information.

What is eye tracking?

Eye tracking, also called visual tracking, is the eyes’ ability to track from left to right in an efficient manner and to follow moving objects.

Eye tracking problems are successfully treated with vision therapy.

Eye movements should be quick, consistent and smooth.

Eye tracking is critical to success in sports and school. The ability to track a ball or words on a page are affected when a person has poor eye tracking skills.

Poor eye tracking skills can cause difficulty in math, reading and writing. The issue is not with the eyes themselves, but the eye muscles. With poor eye tracking, eye motions may lack smoothness, causing vision to be jumpy. This can be a big contributor to dyslexia symptoms.

If you suspect your child has a learning difficulty, contact an eye doctor near you, who can diagnose and treat any visual problems.

Eye tracking symptoms  

Some of the symptoms associated with eye tracking deficits include:

  • Difficulty paying attention
  • Clumsiness
  • Difficulty copying from the board at school
  • Guessing of words
  • Guided reading – uses a finger when reading
  • Loss of place when reading, writing, or copying
  • Omits words or transposes words when reading
  • Overwhelmed by pages of text
  • Poor accuracy with word endings
  • Poor awareness of punctuation
  • Poor reading comprehension, fluency and speed
  • Poor handwriting
  • Poor sports performance
  • Skips sentences
  • Resists or avoids reading
  • Re-reads words or sentences
  • Reverses words or letters
  • Rubs or squints eyes when reading
  • Tilts head when reading
  • Words or text may appear to float or move on the page

Vision therapy and eye tracking

The best way to treat a visual tracking disorder is with vision therapy. 

Vision therapy is a customized program to help strengthen the eye-brain connection, which is often weak in a person with visual tracking problems. It involves specific exercises designed to teach the eyes how to move smoothly from one place to another.

Sometimes reading lenses and/or bifocals can be helpful to reduce eye tracking symptoms. Therefore your eye doctor may recommend a vision therapy program along with lenses.

Vision therapy can be more effective for adult patients, as they are typically more motivated in therapy. 

Once an adult starts to notice the results of vision therapy with their own eyes they realize how beneficial it can be for them, motivating them to improve even further.

What is vision therapy?

Vision therapy is a personalized program of a series of progressive therapeutic eye exercises that help patients improve their visual skills.

The improved visual skills are as a result of enhanced communication between their eyes and the brain. It is an individual and custom-designed treatment program, often used in conjunction with other treatments such as eyeglasses or eye surgery.

Is vision therapy effective for adults?

Many people mistakenly believe that vision therapy is just for children. However, vision therapy is just as effective for adults as it is for children.

Adults can succeed with vision therapy thanks to neuro-plasticity — the brain’s ability to modify, change, and adapt.

Thanks to neuroplasticity, the brain remains dynamic and flexible throughout life. Additionally, adults are usually highly motivated to improve their visual skills, giving them the energy and determination to push through any difficult obstacles and improve their office performance.

Vision therapy can treat a variety of vision conditions:

Lazy eye and vision therapy

Amblyopia, commonly known as a “lazy eye,” is a neuro-developmental vision condition. Lazy eye develops when one eye is unable to achieve normal visual acuity, causing blurry vision in the affected eye, even with corrective eyewear. The condition also commonly presents with poor depth perception and reading difficulties.

Vision therapy has been shown to considerably improve lazy eye, even in Adults, by re-training the visual system.

Vision therapy for adults can be very effective, but tends to take longer to achieve optimum results. Ultimately, adults can often train their eyes to work together to achieve clear and comfortable binocular vision.

Vision therapy programs may include treatment for:

  • Accommodation (focusing)
  • Pursuits (eye tracking)
  • Fixation (visual gaze)
  • Saccades (switching eye focus, “eye jumps”)
  • Stereopsis (3-D vision)
  • Spatial skills (eye-hand coordination)

Schedule an appointment with a vision therapy eye doctor to help improve your visual skills.

Convergence insufficiency and vision therapy

Convergence insufficiency (CI) is a binocular vision condition that can affect adults.

Convergence insufficiency affects eye muscle and near vision coordination. Convergence of the eyes occurs when the two eyes need to focus on a close object, such as a book or computer. Convergence insufficiency means the eyes struggle to focus for near tasks like reading and writing, affecting attention to tasks and work performance`.

Vision therapy is the most effective treatment for CI, as standard eyeglasses, contact lenses, medications, and surgery cannot treat the condition.

In many cases, your eye doctor will prescribe prismatic (prism) glasses in combination with vision therapy, as they decrease some CI symptoms. Although prism eyeglasses can relieve symptoms, they are not a “cure” and the patient typically remains dependent on the prism lenses.

Vision therapy focuses on training the eyes to work together to improve depth perception, clear binocular vision and 3-D vision. The goal of vision therapy is to stimulate the communication between the eyes and brain, to enable clear and comfortable vision at all times.

Treatment exercises for CI may include:

  • Depth perception practice
  • Focusing for near and distance
  • Eye tracking with pursuits and saccades
  • Training with computerized technology
  • Specialized equipment and tools such as prisms and lenses

Eye turns (strabismus) and vision therapy

Strabismus occurs when the two eyes are unable to focus together on one object and maintain proper alignment — one eye looks directly at the object, while the other eye points in a different direction. Strabismus does not go away on its own.

Vision therapy can a highly effective treatment for adults with eye turns and strabismus. 

A vision therapy program for strabismus can help improve:

  • Binocular vision
  • Eye alignment
  • Eye focusing
  • Eye teaming
  • Eye movements
  • Visual processing

A vision therapy program for strabismus may include therapeutic lenses, prisms and filters. Vision therapy involves ocular muscle training as well as training and development of the eye-brain connections required for clear and comfortable vision — resulting in a lasting cure.

A vision therapy program is sometimes recommended by your eye doctor after strabismus surgery in order to re-train the visual system. It is important to treat strabismus as early as possible, as the eye turn may be a result of a serious health issue.

What is reading fluency?

Reading fluency is the ability to read accurately, smoothly and with expression. Fluent readers recognize words automatically, without struggling over decoding issues. As they read, the words sound natural, as if they’re speaking.

Fluency is an essential classroom skill as it bridges the child’s word recognition to their comprehension. 

It allows students time to focus on what the text is saying and enables them to make connections between what they are reading and their own background knowledge. They are able to concentrate on comprehension.

Non-fluent readers sound choppy and read slowly. They spend more time decoding, leaving less time and energy for comprehension. They often have to read the same passage several times to comprehend what they are reading.

Reading fluency and vision

Reading fluency is dependent on the strength of visual skills such as accommodation, binocular vision, convergence, saccades, and visual fixation. Many children benefit with reading glasses, while others require a program of vision therapy to improve their visual efficiency skills.

A deficiency in any of these vital visual skills can result in reading difficulties, which can  impact a child’s ability to learn.

Which visual skills are necessary for reading?

  • Accommodation – the eyes’ ability to switch focus between two distances while maintaining clear vision.
  • Binocular fusion – the brain’s ability to form a single image using the distinct visual information it receives from each eye.

As many as 90% of people who use computers daily report eye fatigue symptoms.

Vision is our primary sense, but most people take their eyes for granted. As we rely more on digital devices throughout our lives, our eyes are starting to feel the fatigue.

What is eye fatigue?

The technical term is asthenopia, but many may know it as eye fatigue or  eye strain. When caused by using a digital screen it’s called computer vision syndrome (CVS) or digital eye strain (DES).

Eye fatigue happens when our eyes experience pain due to being overworked beyond their capacity.

Eye fatigue signs occurs when the muscles in the eye either become fatigued, fail to receive enough hydration and rest from harsh computer screen glare over long periods.

Over time, eyes tend to feel tired and ache, causing difficulties in maintaining attention and concentration.

For some people, their eyes are overworked to a point that they begin to lose concentration and experience disabling eye fatigue, due to glare, air pollutants and long exposure to harmful rays.

When this occurs, it is important to recognize the signs of eye fatigue and then also rest your eyes and take a break from screens or any other activity that requires your eyes to focus intensely.

Schedule an appointment with an eye doctor near you to evaluate your eyes for eye fatigue.

What causes eye fatigue?

Eye fatigue and tiredness occurs when your eyes get tired from being used intensely, such as working at a computer or driving a car for extended periods. 

In some cases, signs and symptoms of eye strain indicate an underlying eye condition that needs treatment. While you may not be able to change your job, or all the factors that are causing eye strain, you can reduce it.

A common causes of eyestrain is Binocular Visual Dysfunction (BVD).

If you experience tiredness or fatigue, contact an eye doctor near you, who can diagnose and treat the visual issues of this condition.

SEE RELATED: 2021 Update: BVD and Neck Pain

What is Binocular Visual Dysfunction?

The symptoms of ocular fatigue, tired eyes, blurring, headaches, and occasionally double vision. are brought on by intense use of the eyes for visual tasks.

Binocular Visual Dysfunction (BVD) is a misalignment between the two eyes, requiring micro-prism lenses.

For some it can occur while concentrating on a visually intense task such as reading fine print or using the computer for hours at a time. These tasks can unconsciously cause the muscles in the eyelids, face, temples, and jaw to clench, leading to discomfort or pain from overusing those muscles.

When eye strain stems from the use of a digital device, it is called Digital Eye Strain (DES) and often results from Binocular Visual Dysfunction (BVD).

Struggling to see in dim light or an extremely bright or glary environment can also bring on eye strain.

People are found to blink less when staring at a digital screen. This decreased blinking may lead to dry eye syndrome.

The inability to make both eyes work together, due to BVD, is a leading cause of eye strain.

What are the best treatments for binocular vision problems?

Vision therapy and micro-prism lenses successfully treat BVD and CI.

1. Micro-prism Lenses

Prismatic (prism) lenses work to correct eye misalignment by manipulating incoming light before it enters the eyes so that when the images from the two eyes reach the brain, the brain can fuse them into a single image.

The prisms in the glasses ‘trick’ the brain into thinking the eyes are properly aligned, causing them to see just one object and preventing eye muscle strain that can cause headaches.

Micro-prisms are a very low amount, usually under 2 dioptres, however their impact can significantly reduce the headaches suffered by many people.

2. Vision Therapy 

Patients with CI or BVD are also often treated with a customized program of vision therapy.

Vision therapy is a program to improve the communication between the brain and the eyes, further supporting the visual system and alleviating the symptoms of BVD or CI.

Usually, patients find that their symptoms gradually subside or completely disappear when they wear prescribed prism lenses, which can be even further helped by completing a program of vision therapy.

While eye fatigue may be alleviated by making some lifestyle and behavioral changes, your eye doctor may discover that a functional vision problem is the underlying cause of eye fatigue.

A common question asked by parents

Parents of school-age children who have struggled with reading and learning are often looking for answers to many questions.

Most likely the most frequent question asked by parents is, “Why does my bright child continue to have difficulty with reading fluency and paying attention in the classroom?”

To provide some direction, two years ago the VisionHelp Group interviewed educational specialist, Wendy Rosen, author of the book, ‘The Hidden Link Between Vision and Learning, Why Millions of Learning Disabled Children are Misdiagnosed’.

In her video, ‘Misdiagnosing Learning Disabilities’, Wendy mentions the diagnosis, “Convergence Insufficiency”, a binocular vision dysfunction usually associated with a reduced convergence ability and commonly identified with the Red/Green Penlight Near Point of Convergence (NPC) test.

This test which can be done in about 30 seconds is one tool in the optometrist’s use to evaluate a patient’s vision skills.

Harvard Medical School

Harvard Medical School research published in the American Journal of Ophthalmology entitled: ‘Receded Near Point of Convergence is Not Diagnostic of Convergence Insufficiency’.

What they found was that the majority (89%) of post-concussed patients had a reduced near point of convergence (NPC).

Other results showed that these patients also had high incidence of;

  1. Poor visual tracking (oculomotor dysfunction)
  2. Reduced eye focusing problems (accommodative dysfunction) and
  3. Difficulties with eye teaming and
  4. Problems with focusing flexibility (binocular vergence/accommodative dysfunction)

The conclusions by the JAO Harvard researchers was that, “Because treatment options for the various oculomotor dysfunctions differ, it is prudent that these patients undergo a thorough examination of their vergence and accommodative systems so that an accurate diagnosis can be made and appropriate treatment prescribed.”

Complex visual problems should be addressed with a comprehensive evaluation process followed by a comprehensive model of treatment to meet the patient’s individual visual needs.

Vision Skills and Reading

Research shows that those children with vision-based reading and learning problems also have a high frequency of oculomotor, accommodative and binocular vergence/accommodative problems!

Therefore, the importance of assessing binocular vision skills, plus additional sensorimotor areas, is critical to assessing those children with reading and learning problems.

When the initial testing diagnosis identifies a reduced near point of convergence, it is essential to have a comprehensive sensorimotor and visual perceptual evaluation so that an accurate diagnosis can be made.

Vision Therapy

Once identified, as outlined by the American Optometric Association CPG-18, the best approach to treatment involves a comprehensive model of office-based vision therapy.

Vision therapy includes working one-on-one with a skilled vision therapist, sessions are typically 45-60 minutes, 1-2 times per week in-office with assigned home support activities.

Vision therapy should be provided in conjunction with lenses, prisms, and/or therapeutic tints prescribed and supervised by an experienced Doctor of Optometry in developmental vision and rehabilitation.

Over 50% of all adults experience dry eyes.

Other than dryness of the eye, symptoms of dry eye include burning, irritation and grittiness. While studies have shown that certain foods help the eyes stay hydrated, there are certain fatty acids, vitamins, and trace elements that can be added to your diet.

Yes, there are foods that are not only good for overall health but also improve the quality of tears and eye comfort.

Omega fatty acids

If the outer layer of the lubricating tear film is disrupted, it leads to dry eye symptoms like redness, itchiness, and burning.

Omega fatty acids are responsible for stabilizing the oil layer in the tear film, making them important for lubricating your eyes.

In addition, omega fatty acids have an anti-inflammatory effect, so both Omega-3 and omega-6 fatty acids are essential nutrients.

Foods high in omega fatty acids include:

  • Fish: mackerel, cod, trout, herring, salmon
  • Oils: canola oil, rapeseed oil, flaxseed oil, sunflower oil, walnut oil
  • Meat: pork, beef and lamb
  • Dairy: cheese and milk products

Contact an eye doctor near you, if you would like to find out more about other foods which contain vitamins that are good for your dry eyes.

Vitamins

There are a number of vitamins that also can help boost general eye health and dry eye.

Vitamin A (retinol)

Vitamin A deficiency, which usually occurs in developing countries, can cause an increase in dry eye. Adding foods rich in Vitamin A like pumpkins, apricots, carrots, tomatoes, spinach, dairy products, and liver can help. It also helps protect the surface of the eye.

Vitamin B2

Vitamin B2 is found in avocados, broccoli, whole-grain products and dairy products. It also protects the eyes from cell damage.

Vitamin B6

Vitamin B6 is found in foods such as goose, potatoes, kale, salmon, mackerel, and sardines. It is needed for a functioning tear film.

Vitamin B12

Foods which contain Vitamin B12 are beef liver, calf’s liver, pork liver, and mackerel. It is also found in smaller amounts in dairy products and eggs. It is also important for lubricating the eye.

Vitamin C

Broccoli, rosehip, acerola berries, peppers, and Brussels sprouts all contain Vitamin C. It protects against oxidative stress, and plays an important role in maintaining a functioning tear film.

Vitamin E

Mackerel, wheat germ oil, sunflower oil, spinach, peppers, mangos, and red currants all contain Vitamin E. It is required to protect your eyes against cell damage as well as dry eyes.

Lutein and Zeaxanthin

Lutein and zeaxanthin are antioxidants that help prevent many chronic eye diseases including dry eye. They also keep cells functioning correctly and healthy. Foods rich in these antioxidants include leafy greens like kale, spinach and romaine lettuce. They can be found as supplements.

Zinc

Zinc plays an important role in keeping eyes healthy. Zinc is responsible for transporting vitamin A from the liver to the retina. It also produces melanin, a pigment that protects your eyes. Zinc can be found in whole grains, dairy, sweet corn, peas, lentils, and nuts.

Drinking Water Hydrates Your Eyes

While water is not a vitamin drinking water is important for the eyes. Staying hydrated can help improve eye comfort. Water is great for your skin, kidneys, bowels, and your eyes.

Staying hydrated and eating healthy helps to ensure that your eyes get the minerals and vitamins they need.
