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.
 

If you’ve had a vision screening recently, you might say, “My vision is fine! I don’t need a comprehensive eye exam.”

But a vision screening provides a limited perspective on the overall health of your eyes. It’s a bit like getting your blood pressure checked and not getting the rest of your annual physical. You’ll have useful information, but it’s not the whole picture.
 

What are the Benefits of a Comprehensive Eye Exam?

Comprehensive eye exams evaluate all aspects of your vision and eye health.

The comprehensive eye exam looks at your eye externally and internally for any signs of eye disease, then tests your vision in a variety of ways.

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 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 be 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. 
 

What to expect from a vision therapy appointment?

Vision therapy is generally conducted as an in-office treatment, under the close supervision of your eye doctor. Each vision therapy treatment plan is personalized; tailored to the specific individual needs of each patient. Most patients can expect to schedule hour appointments once or twice a week. You may also be given specific exercises to complete at home, which will support the progress that you are making during your in-office appointments. The components of Vision Therapy Treatment are non-invasive and drug-free, making VT suitable for the vast majority of patients, regardless of their age, health and history. For many people, vision therapy is a safe alternative to conventional eye surgeries.
 

There are various techniques that can be involved in vision therapy. These include, but aren’t limited to:
 

• Prisms
• Patches
• Occluders
• Therapeutic lenses
• Exercises
• The use of tools designed specifically for use in vision therapy exercises

By attending regular vision therapy appointments, patients can see an improvement in their vision, visual comfort and experience an overall improvement with the ease in which they use their eyes for daily activites.
