It is common knowledge that exercise plays a critical role in healthy living. Exercise can help improve energy levels, lower blood pressure, aid in weight loss, helps to build muscle and so much more. But one benefit of exercise that is not as well known is the profound impact on your eyesight. 

Based on recent research, eye conditions are usually a direct result of a health issue such as high blood pressure, diabetes, high cholesterol level, etc. While some of these diseases are unavoidable, exercising regularly can definitely help in the prevention of these diseases and in doing so, help keep the eyes healthy. In addition to physical exercise, there are even some eye exercises that can be done to keep your vision healthy. Some examples are focusing on certain points, rolling your eyes in different directions, writing with the eyes, etc.
 

Cataracts and Exercise

According to a study in 2003 and another in 2006, a relationship was discovered between an increase in exercise and a decrease in cataract. It emphasized that there is a greater chance for cataract if there is an absence of physical activity. This implies that taking a light walk or jog around your house or on a field track consistently can contribute to the fight against cataracts.
 

Macular Degeneration and Exercise

According to one study, exercising three times or more on a weekly basis reduces ones’ chances of developing exudative macular degeneration. Exudative macular degeneration occurs when blood vessels grow beneath the retina that are not needed and then leak fluid and blood into the eyes.
 

Glaucoma and Exercise

One major cause in the development of glaucoma is an increase in ocular perfusion pressure. Very light exercises like jogging or walking at least three times weekly helps to reduce the intraocular pressure and improves the flow of blood to the optic nerve and retina.
 

The benefit of eye exercises

• Protects against dry eyes. Eye exercises help maintain and improve the fluid level in the eyes, thus eliminating the probability of dry eyes because as the eyes are being exercised say by rotation, there is the tendency that fluid is produced.

• Reduces eye strain and tension. Exercising the eyes daily helps in reducing the strain and tension that has been placed on the muscle. Exercises like rolling the eyes and writing with the eyes help in the contracting and relaxing of the eye muscles. Long hours of study or use of a computer can cause blurry vision, but through exercise, clarity can be achieved by eliminating tension and unnecessary pressure.

• Make the eye muscles flexible. Exercises like shifting and swinging the muscles of the eyes help promote flexibility in the muscles of the eyes. Just like exercise helps the body muscles, the same thing applies to eye exercises.

Keratoconus is a terrifying diagnosis to those that have experienced it. To compound issues, many patients complain that they had poor initial treatment due to a lack of understanding about the disease. If proper treatment is not achieved, individuals may experience a rapid deterioration in their ability to see. This leads to a reduced quality of life. You can reduce the stress related to a keratoconus diagnosis and increase the benefits of treatment by understanding your treatment options.
 

Understanding Keratoconus

Keratoconus is an eye disease that causes the cornea to thin and bulge. This bulge generally takes on the appearance of a cone. As light enters the eye, it becomes distorted by the cone causing vision abnormalities.

Modern research is connecting keratoconus with an enzyme imbalance in the cornea. This imbalance leaves the eye susceptible to oxidative free radicals. Keratoconus has also been linked to UV damage, excessive eye rubbing, poorly fitting contacts, and chronic eye irritation.
 

Treatment Options

While your eye professional will have the best understanding of what treatment option is right for you, we have compiled ten of the most common treatments here.

• Corneal Cross-linking (CXL) – There are two different types of this procedure, but they both introduce riboflavin to the cornea in order to strengthen the corneal tissue and stop the bulging from progressing.

• Custom Soft Contact Lenses – Soft contacts are generally more comfortable to wear than gas permeable lenses. Recently, some contact companies have been able to create a contact specifically to correct the issues related to mild and moderate cases of keratoconus.

• Gas Permeable Contact Lenses – Gas permeable lenses are a hard contact lens that physically forces the eye to adhere to the lens shape. This allows for the correction of keratoconus. The fit is often time-consuming and may take several different lenses to achieve the proper fit.

• Piggybacking Contact Lenses – This method is used for individuals who require a gas permeable lens but cannot tolerate wearing rigid contacts. Piggybacking utilizes a soft lens placed on the eye first, and then a gas permeable lens is placed over the top. This offers the comfort of soft contacts with the rigidity and clarity of the gas permeable lenses.

• Hybrid Contact Lenses – Hybrid contact lenses were designed specifically for keratoconus. This technology blends a rigid contact lens center with a softer edge, or skirt, of the contact

• Scleral and Semi-Scleral lenses – These lenses are gas permeable lenses but cover a larger area of the eye than a standard rigid lens. These lenses don’t put pressure onto the cone shape of the eye. The reduced pressure results in a more comfortable fit for patients.

• Prosthetic Lenses – This lens is used specifically for patients that have very advanced keratoconus and have ruled out other options. The advanced scleral lens also doubles as a protective prosthetic shell. There are special requirements to qualify for this lens though, so check with your eye care professional if this is an option for you.

Sports vision is a growing niche in the eyecare industry, helping athletes improve their performance skills through the enhancement of visual skills. While regular eye exams are important for checking the health of your eyes and your visual acuity (how clearly you can see a still object at different distances), sports vision testing is recommended for anyone who takes their athletic performance seriously. 
 

Visual skills needed for sports performance

There are several key visual skills that are enhanced through sports vision programs for athletes that aim to achieve their optimal sports performance, these include:

Dynamic visual acuity: this refers to the patient’s ability to see objects clearly while in motion. This is exceptionally important as hand-eye coordination and reflex reactions are essential for success in most sporting activities.

Contrast sensitivity: good contrast sensitivity is needed to determine the difference between an object and its surroundings. Contrast sensitivity is particularly important in situations where there may be low light, fog or glare that could diminish the natural contrast between objects and backgrounds. 

Eye tracking: this refers to the ability to follow a fast-moving object, such as a ball or puck.

Switching eye focus: athletes need to be able to change their focus quickly and accurately from one distance to another. 

Binocular vision skills: also known as eye teaming skills, these skills determine how well your eyes work with one another to produce a single, clear image.

Processing speed: visual processing speed is defined as the amount of time it takes to make a correct judgement about a visual stimulus – for example, how fast a ball is travelling towards them. 

Peripheral awareness: athletes also need to be able to be aware of what is happening at the edges of their vision while also concentrating on a fixed object in front of them.

Sports vision testing can enable your eye doctor to spot any weaknesses that you may have in any of these key visual skills. By identifying them, it is possible for you to undergo treatment to overcome theses issues and meet your specific goals that will ultimately enhance your overall athletic performance. This is known as sports vision training.
 

Regular eye exams are important for children since their eyes can change significantly in as little as a year as the muscles and tissue develop. Good eyesight is critical for a child’s life and achievements since success in school is closely tied to eye health. School demands intense visual involvement, including reading, writing, using computers, and blackboard/smartboard work. Even physical activities and sports require strong vision. If their eyes aren’t up to the task, a child may feel tired, have trouble concentrating, have problems in school or have difficulty playing their favorite games which may affect their overall quality of life.
 

When to Perform a Pediatric Eye Exam?

According to research, a child should have an initial screening between 6 and 12 months of age. After that, routine eye health and vision screenings throughout childhood should be performed in order to help detect any abnormalities as their eyes develop. Then, unless otherwise recommended, every two years thereafter until the age of 18.

For a newborn, an optometrist should examine the baby’s eyes and perform a test called “red reflex test” which is a basic indicator that the eyes are normal. In a case that the baby is premature or at high risk for medical problems for other reasons, has signs of abnormalities, or has a family history of serious vision disorders in childhood, the optometrist should perform a comprehensive exam.

A second eye health examination should be done to infants between six months and the first birthday. This examination includes tests of pupil responses to evaluate whether the pupil opens and closes properly in the presence or absence of light, a fixate and follow test to determine whether the baby can fixate on an object such as a light and follow it as it moves, and a preferential looking test which uses cards that are blank on one side with stripes on the other side to attract the gaze of an infant to the stripes and thus vision capabilities can be assessed. Infants should be able to perform this task well by the time they are 3 months old.

For a Preschooler, between the ages of 3 and 3½, a child’s visual acuity and eye alignment should be assessed. If the child is diagnosed with misaligned eyes (strabismus), "lazy eye” (amblyopia), refractive errors (astigmatism, myopia, hyperopia) or any other focusing problems, it’s important to begin treatment as soon as possible to ensure successful vision correction and life-long benefits.

At School age or upon entering school, the child’s eyes should be screened for visual acuity and alignment. In this age group, nearsightedness (myopia) is the most common refractive error and can be corrected with eyeglasses.
 

Generally, despite knowing how important the role of our eyes is in our day to day functioning, we tend to neglect the day to day care necessary to maintain optimal eye health. Just close your eyes for a minute or you put a non-transparent cloth across your eyes and try to walk around your home or workspace. It is quite difficult, right? That is how indispensable the eyes are.

While it is common knowledge that eye issues are a result of eyestrain or aging, most people are ignorant of the fact that an unbalanced diet, as well as deficiency in certain nutrients, can also facilitate eye issues. This implies that eating healthy means that there are certain nutrients that can help reduce the risk of eye issues. Some of these nutrients include omega-3 fatty acids, lutein, copper, zeaxanthin, zinc, vitamin E, A, C, and beta-carotene. For healthy eyes, there are foods that should be part of your diet daily. They include:

1. Fish- Fish is very rich in omega-3 fatty acids, especially oily fish which have oil inside their body tissue and guts. They are regarded as the major source of omega-3 fatty acids which help in improving the immune system and brain function. More so, it helps in the development of the eye and retina and in keeping the eyes from dryness. It is therefore important to incorporate fish into your diet about 3 times a week. Incorporating fish rich with this needed nutrient such as salmon, tuna, sardines, trout, herring, mackerel, and anchovies about 3 times a week is important in helping to maintain optimal eye health.

2. Eggs- The yolk of an egg contains a combination of the nutrients vitamin A, zeaxanthin, and lutein which help to safeguard the cornea, reducing the chances of suffering from cataracts and macular degeneration and zinc which keeps the retina healthy and aids night vision. Eggs are very complimentary food as it can go with other foods and can also take various forms based on your taste.

3. Carrots- This is the most common food for eye health. It contains beta-carotene and vitamin A which protect the surface of the eyes and help to prevent infections. Vitamin A is a form of protein known as rhodopsin and it is tasked with the responsibility of aiding the eyes in absorbing light. A lack of vitamin A is the reason why there are about 500 thousand blind children every year.  Carrots are easy to get and very affordable. They can serve as snacks or be sliced or diced into salads. 

4. Nuts and Legumes- Legumes and nuts provide a lot of vitamin E and omega-3 fatty acids which guard the eyes against age-related disorders. Brazilian nuts, peanuts, walnuts, lentils, and cashews are perfect examples of legumes and nuts and can be eaten as a form of dessert or taken as snacks based on your choice.

5. Citrus Fruits- Citrus fruits are rich in vitamin C, an essential nutrient for healthy eyes. Vitamin C helps in keeping the blood vessels in the eyes healthy. It also stands against cataracts, and with other nutrients, it helps against macular degeneration. Citrus fruits include oranges, grapefruits, and lemons. The good thing about this food is that they can be consumed on their own or turned into a juice.
 

Vision therapy is a treatment plan that is intended to develop and improve a patient’s visual skills and abilities, with the goal of making their day-to-day life easier. You may also hear Vision Therapy referred to as VT. Although most commonly associated with children, whose visual skills are still naturally developing, adults can also benefit from vision therapy.
 

Any patient who does not have the necessary visual skills could find themselves suffering from a range of unpleasant symptoms, including headaches, eye fatigue, stiff neck, and double vision. Fortunately, vision therapy is a simple, painless technique to help patients to enhance their visual skills and overcome any issues that they may have been experiencing.
 

Skills that can be developed and improved through vision therapy

Vision therapy has been shown to be an effective way of developing and improving the following visual skills, all of which are important for day-to-day life. 
 

Tracking: this refers to the ability to follow a moving object smoothly and accurately with both eyes – such as moving traffic or a ball coming towards you.
 

Depth perception: this is the ability to judge relative distances of objects and move accurately in a 3D space – for example, being able to walk down a flight of stairs.
 

Peripheral vision: this refers to the edges of your vision and your ability to assess what’s happening in your peripheral vision while paying attention to something directly in front of you.
 

Acuity at different distances: this is the ability to see clearly enough to identify and understand objects at both near and far distances. 
 

Fixation: enabling patients to quickly and accurately look at, identify and understand stationery objects one after the other, for example, reading word to word. 
 

Binocular vision: the ability for both eyes to work together in perfect synchronization.
 

Shifting focus: patients with this skill can look quickly at different distances without momentary blur. 
 

Visualization: a valuable visual skill that enables patients to form and retain images in their head. 
 

Many people don’t realize that eyelashes are both functional and attractive. The purpose of eyelashes is to act as a first line of defense for our eyes, preventing airborne dirt, dust and other debris from reaching the delicate tissues of our eyes. You probably don’t know that when your eyes are closed, your eyelashes form a nearly impenetrable barrier against foreign irritants entering the eyes. 

Unfortunately, we aren’t all blessed with naturally thick, luscious lashes. In fact, many people choose to get artificial eyelashes or eyelash extensions to make them appear longer or thicker than they really are. Unfortunately, the challenge of achieving voluminous eyelashes is even greater if you suffer from a condition called hypotrichosis.
