Computer vision syndrome

COMPUTER VISION SYNDROME

Computer vision syndrome, also referred to as digital eye strain, describes a group of eye- and vision-related problems that result from prolonged and uninterrupted computer, tablet, e-reader and cell phone use.

These symptoms may be caused by:

Poor lighting.
Glare on a digital screen.
Improper viewing distances.
Poor seating posture.
Uncorrected vision problems.
A combination of these factors.

Diagnosis

comprehensive eye examination with special emphasis on visual requirements at the computer or digital device working distance

Patient history to determine any symptoms the patient is experiencing and the presence of any general health problems, medications taken or environmental factors that may be contributing

Visual acuity measurements

A refraction to determine the appropriate lens power needed to compensate for any refractive errors

Testing how the eyes focus, move and work together. To obtain a clear, single image of what is being viewed

How To Prevent Eye Strain

Prevention or reduction of the vision problems associated with CVS or digital eyestrain involves taking steps to control lighting and glare on the device screen, establishing proper working distances and posture for screen viewing and assuring that even minor vision problems are properly corrected.

Suggestions for computer vision syndrome sufferers

Don’t take a vision problem and headache to work.

Even if glasses are not needed for driving, reading or other activities, they still may offer benefits for a minor vision problem that is aggravated by computer use. A mild glasses prescription may be needed to reduce vision stress on the job. It’s a good idea for computer users to get a thorough eye exam every year.

Take treatment for headaches like Tension headaches and migraine

Glasses should meet the demand of the job.

If glasses are worn for distant vision, reading or both, they may not provide the most efficient vision for viewing a computer screen, which is about 20 to 30 inches from the eyes. Tell the doctor about job tasks and measure on-the-job sight distances.

Minimize discomfort from blue light and glare.

Special lens tints and coatings can reduce the harmful impact of blue light. Minimize glare on the computer screen by using a glare reduction filter, repositioning the screen or using drapes, shades or blinds. Also, keeping screens clean; dirt-free and removing fingerprints can decrease glare and improve clarity.

Adjust work area and computer for comfort.

When using computers, most people prefer a work surface height of about 26 inches. Desks and tables are usually 29 inches high. Place the computer screen 16 to 30 inches away. The top of the screen should be slightly below horizontal eye level. Tilt the top of the screen away at a 10- to 20-degree angle.

Use an adjustable copyholder

Place reference material at the same distance from the eyes as the computer screen and as close to the screen as possible. That way the eyes won’t have to change focus when looking from one to the other.

Lubricants

To minimize the chances of developing dry eye when using a computer, try to blink and use Lubricant Eye Drops frequently. It helps keep the front surface of the eye moist.

Rest breaks

To prevent eyestrain, try to rest your eyes when using the computer for long periods. Resting the eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow the eyes a chance to refocus.

What Causes Computer Cision Syndrome?

Characters, when read on a computer screen, don’t have the same level of contrast and definition as printed materials. This lack of contrast makes it harder for your eyes to focus.

Who Is Affected

Anyone working on a computer for extended periods has an increased risk of developing computer vision syndrome. When you stare at a screen, you are forcing your eyes to focus and refocus for long periods. As a result, your eyes are using more muscles, causing fatigue and tired eyes.

What Can I Do To Reduce Symptoms?

It’s easy! consult your eye doctor about their recommendations on how you can handle CVS

Your eye doctor may do a few tests to detect vision problems Depending on the results, your doctor may recommend computer eyewear to protect your eyes or tips and tricks habits to reduce your symptoms.

What Is Computer Eyewear?

Computer eyewear are prescription glasses specifically designed for work on a computer. Which will reduce glare and discomfort while working long hours of digital use.

Are There Different Types Of Computer Lenses?

Yes! Computer lenses are available in both single-vision and progressive lens options to fit your vision needs.

I Don't Have Computer Vision Syndrome Now. Should I Still Look Into Computer Eyeglasses?

Yes. Even though you may not have computer vision syndrome now, you can still develop symptoms down the road. Many individuals experience reduced productivity and accuracy when working behind a screen, even without vision problems.

The 20/20/20 Rule

when using digital devices for an extended period. Every 20 minutes, look 20 feet away for 20 seconds. This exercise gives your eyes a break from the continued work of focusing on your computer screen.
