Just a few decades ago, computer vision syndrome (CVS) was not known or understood. However, with an increase in the role of computers in our lives, it has become an increasingly common issue. Researchers believe that 50-90% of people who use computers in their daily lives have experienced CVS to some degree. The amount of time that many people stare into a computer screen is increasing, which puts significant strain on our eyes.

CVS is not considered a single specific problem, but a suite of issues. And with the increased use of school computers, tablets and smartphones, children are also becoming more susceptible to CVS.

This syndrome is similar to many other repetitive motion type conditions such as carpal tunnel syndrome. Problems can start because as we are reading text on a screen, our eyes move in a repetitive motion throughout the day. Once the issue has started, continuing the same behavior can worsen any symptoms. While reading alone uses the same motion, digital screens add flicker, contrast, glare, and light that all put additional strain on our eyes.

Issues may also be accelerated if you should be wearing some type of corrective lens, but don't, and are therefore putting additional strain on your eyes.

Aging can also speed up the progress of these issues. Around the time that people turn 40, the lenses of the eyes begin to harden due to a disease called presbyopia, which affects your ability to see closer objects.

What Happens if I have CVS?

There is currently no proof that CVS causes long-term vision impairment or blindness. Continuing to use a computer or any other type of screen can continue to be an annoyance or reduce your ability to see properly. Some of the warning signs of CVS are:

• Blurred vision

• Double vision

• Red or dry eyes

• Headaches

• Neck pain

• Back pain

• Eye Irritation

If you don’t properly treat CVS when these symptoms occur, you may begin to notice that you suffer from a decrease in overall quality of life or job performance.
 

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.
