Computer eyewear and computer vision syndrome

Spending a lot of time every day in front of a computer, tablet, or mobile phone can cause symptoms of computer visual syndrome (CVS) or digital eyestrain. Lots of people experience this eye fatigue and irritation. Computer glasses are glasses specially designed to work comfortably at your computer or while using other digital devices.

Computer vision syndrome and digital eye strain

CVS is a collection of symptoms caused by prolonged use of a computer or digital device. Symptoms include eyestrain, dry eye, headache, and blurred vision. Many people try to compensate for these vision problems by leaning forward or looking at the bottom of their glasses. This often causes back and shoulder pain.

Symptoms appear because there may be distance, glare, inadequate lighting, or screen brightness problems between the eyes and the brain. Prolonged focus on the screen at a particular distance at a time can cause fatigue, fatigue, dryness, and a burning sensation. one


People with CVS may experience the following symptoms:

• Dry Eye

• Headache

• Eye irritation

• Blurry vision

• Sensitivity to light

 Temporarily unable to focus on distant objects (pseudomyopia or accommodative seizures)

• Diplopia

• Squinting

• Neck and shoulder pain

You may experience digital eyestrain while using your cell phone or tablet, but the same problem does not occur on your computer screen. We usually have mobile phones and tablets close to our eyes, so these devices can notice this more than computer screens, which are generally far away.

CVS symptoms can also be caused by presbyopia, a vision disorder that develops with age. Presbyopia is the loss of the eye’s ability to change focus to see close objects. It is usually noticed around 40 years

How to deal with

If you have eye problems while using your computer, the following tips are worth trying.

• Think of computer glasses

• Blink, breathe and stop. Blink more often, take frequent deep breaths, take short breaks every hour

• Use artificial tears for dry or itchy eyes.

• Adjust the light level to reduce glare from the screen.

 Increase the font size of your computer screen

The 20/20/20 rule is also useful for long-term use of devices with displays. Every 20 minutes, take 20 seconds to look from 20 feet away (outside the window, behind your office / house, etc.).

Also, good ergonomics such as proper screen height (looking straight ahead without tipping up and down) and using a better chair with lumbar support can help you deal with the problem. Digital visual fatigue.

How Computer Glasses Can Help

If you think you are experiencing some of the symptoms of CVS, you may benefit from computer glasses. With computer glasses, the entire lens is focused at the same distance, and you don’t have to tilt your head back to view the computer screen.

Computer work involves focusing the eyes over a short distance. Computer screens are generally placed a little further than a comfortable reading distance, so standard reading glasses are generally not enough to alleviate CVS symptoms. Computer glasses make it easy for a person to focus on the distance from the computer screen.

Contact lens wearers may need to wear glasses on their contacts when using the computer.

Computer vision problems also occur in young people, so CVS is not a problem that only exists for people over the age of 40. CVS is fast becoming a common complaint for all age practice groups.

If you spend more than four hours every day in front of your computer, even small, uncorrected vision problems can become more serious.

How to get computer glasses

Your GP or ophthalmologist may prescribe computer glasses to help relieve CVS symptoms.

Take a look at your workspace before booking. It is important that your healthcare provider knows exactly how your workspace is set up, such as the distance between your monitor and your eyes, so that they can prescribe the proper computer glasses.

Also pay attention to lighting. Bright light often causes eyestrain in the office. 4 anti-reflective (AR) coatings can be applied to the lens to reduce the amount of glare and reflected light that reaches the eyes.

Types of lenses for computer glasses

The following lenses are specially designed for computer use.

• Single vision lens – Single vision lens is the simplest type of computer glass. The entire lens is designed to look at the computer screen, providing the widest field of view. Both adults and children love these lenses because the monitor looks clear and unobstructed. However, objects that are far away or closer than your computer screen will appear blurry.

• Flat-top bifocals: Flat-top bifocals look like normal bifocals. These lenses are designed so that the upper half of the lens adjusts to focus on the computer screen and the lower segment adjusts to focus on the closest reading. These lenses have a visible line that divides the two focus segments. These lenses provide a comfortable view of your computer, but objects in the distance appear blurry. In addition, a phenomenon called “frame skipping” may occur. This is a phenomenon that occurs when the viewer moves from one part of the lens to another and the image appears to be “jumping.”

• Varifocal – Some eye care professionals call this lens a “progressive computer” lens. Although similar in design to traditional lineless invisible progressive multifocal lenses, varifocal lenses are much more specific to each task. This lens has a small segment at the top of the lens that shows objects in the distance. The large middle segment shows the computer screen, and finally the small segment at the bottom of the lens shows the lens. Focus on nearby objects. These can also be created on top with a set distance from the computer screen instead of the remote view. This type of lens has no visible lines or segments, so it looks like normal vision.

A good fit is the key

Computer glasses can benefit computer users if they are worn and prescribed properly.

Optometrists and ophthalmologists are well aware of the problems caused by computer vision syndrome and can help you find the right pair.
