Computer Eye Strain, How to relief the symptoms of digital eye strain

Nowadays, it seems like everyone is connected to a phone, computer, or other digital gadget. Digital eye strain is a widespread issue that it is creating.

Mentioned below symptoms of digital eye strain:-

eye discomfort and fatigue

Dry eyes


Blurred vision

Red eyes

Eye blinking

Shoulder and neck pain

Computer eye strain or computer vision syndrome are other names for digital eye strain.

Get a complete eye examination

The most crucial thing you can do to avoid or correct computer vision problems is to have a full eye checkup every year. Tell your eye doctor how frequently you use a computer and other digital devices at work and at home when you get your eye exam.

When you sit down at a computer, measure the distance your eyes are from the screen. Bring this measurement with you to your eye exam so the optometrist may check your eyes at that particular working distance.

Use sufficient light

Eye strain is frequently brought on by illumination that is too bright, whether it be harsh indoor lighting or sunlight entering via a window from the outside.

Your ambient lighting should be around half as bright as what is common in most offices when you are using a computer.

Close the draperies, shades, or blinds to block off any outdoor light. Use fewer fluorescent tubes or light bulbs, or use tubes and bulbs with lesser intensity, to reduce interior illumination.

Position your computer screen such that windows are to the side rather than in front of or behind it, if at all feasible.

Many computer users discover that working away from overhead fluorescent lighting helps their eyes feel better. Use floor lamps that provide indirect "soft white" LED lighting in your office instead of the overhead fluorescent lights, if at all possible.

It can occasionally be more relaxing to switch to "full spectrum" fluorescent lighting instead of standard fluorescent tubes for computer work since it more nearly resembles the light spectrum produced by sunshine. However, if it is excessively bright, even full spectrum illumination can be uncomfortable.

If the overhead illumination bothers you, try minimizing the amount of fluorescent tubes that are mounted over your desk.

Reduce the glare

Computer eye discomfort can also result from glare from light bouncing off walls and completed surfaces, as well as reflections on your computer screen. If feasible, paint the stark white walls a darker hue with a matte finish. Also, think about adding an anti-glare screen on your monitor.

Consider purchasing lenses with an anti-reflective (AR) coating if you wear spectacles. By reducing the quantity of light reflected off the front and rear surfaces of your eyeglass lenses, AR coating lessens glare.

Update the display

Replace your outdated cathode ray tube (CRT) monitor with a flat-panel LED (light-emitting diode) screen with an anti-reflective surface if you haven't yet.

The "flicker" of visuals on outdated CRT screens is a significant contributor to computer eye strain. Even if this flicker is invisible, it can nevertheless cause eye strain and tiredness when using a computer.

If the monitor's refresh rate is less than 75 hertz, complications brought on by flicker are considerably more likely. If you have to use a CRT at work, set the refresh rate to the maximum level.

The highest resolution screen should be chosen when buying a new flat panel display. Resolution and the display's "dot pitch" are connected. Typically, pictures on screens with a smaller dot pitch are crisper. Select a display with a minimum.28 mm dot pitch.

Also, pick a display that is reasonably large. Choose a display with a diagonal screen size of at least 19 inches for a desktop computer.

Adjust the display settings on your Computer

Your computer's display settings can be modified to reduce eye fatigue and strain. In general, these changes are helpful:

Brightness: Set the display's brightness so that it roughly corresponds to the brightness of the workstations around you. Check out the white backdrop of this page as a test. If it seems like a light source, it is too bright. If it seems depressing and dismal, it can be too dark.


Text size and contrast especially while reading or writing lengthy texts should be adjusted for comfort. Usually, a black design on a white background is the most cosy combination..

Colour temperature Technically speaking, colour temperature refers to the range of visible light that a colour display emits. Short-wavelength visible light, like blue, is known to cause more eye fatigue than longer-wavelength colours like orange and red. To improve long-term viewing comfort, adjust the colour temperature of your display to reduce the quantity of blue light it emits.

More regularly blink.

When using a computer, blinking is necessary because it moistens your eyes to avoid dryness and discomfort.

According to research, individuals blink less frequently when looking at a screen—just about one-third as frequently—and many of the blinks they do make only half lid closures.

During extended times of no blinking, tears covering the eye evaporate more quickly, which can lead to dry eyes. Additionally, the dry air in many office environments can speed up the pace at which your tears evaporate, placing you at a higher risk for dry eye conditions.

Ask your eye doctor about artificial tears to use during the day if you experience symptoms of dry eye.

Don't confuse lubricating eye drops with those designed to "get the red out," by the way. The latter can really improve the appearance of your eyes since they include substances that "whiten" your eyes by constricting the blood vessels on their surface. However, they may not always be designed to lessen dryness and irritability.

Try this practice to lower your risk of dry eyes when using a computer: Blink 10 times while shutting your eyes like you're going to sleep every 20 minutes (very slowly). This will aid in moistening your eyes.

Exercise your eyes.

Another factor that contributes to computer eye strain is focusing fatigue. Look away from your computer at least once every 20 minutes and fix your eyes on a distant object for at least 20 seconds to lessen the chance of wearing out your eyes from staring at the screen all day.

The "20-20-20 rule" is what some optometrists refer to as. The focusing muscle in the eye is relaxed while looking far away, which eases tiredness.

Another practice is to focus for 10-15 seconds on something far away, then for the same amount of time on something near up. then turn to face the far-off thing. Ten times total. This exercise lowers your chance of experiencing accommodative spasm, a condition known to occur after extended computer use.

You'll have less computer eye strain if you do one of these exercises. Additionally, to lessen your risk of dry eyes when using a computer, try to blink regularly while performing the exercises.

Take breaks regularly.

Take regular screen breaks during your working day to lower your chance of developing computer vision syndrome and pain in your neck, back, and shoulders (at least one 10-minute break every hour).

To relieve stress and muscular weariness during these pauses, stand up, walk around, and stretch your arms, legs, back, neck, and shoulders.

Customize your workplace.

Place the written pages on a copy stand next to your screen if you need to switch back and forth between a printed page and your computer screen.

Properly illuminate the copy stand. You might wish to use a desk light, but watch out for how it shines on your computer screen or into your eyes.

Computer vision syndrome is also influenced by poor posture. Your workspace and chair should be adjusted such that your feet may rest comfortably on the ground.

Set the distance between your eyes and the computer screen at 20 to 24 inches. To position your head and neck comfortably, the centre of your screen should be 10 to 15 degrees below your eyes.

Think about computer eyeglasses.

You could benefit from having your optometrist change your prescription for eyeglasses to produce specialised computer glasses for the maximum level of comfort at your computer.

This is especially true if you typically wear contact lenses since they could get dry and unpleasant from spending a lot of time in front of the computer.

If you wear bifocals or progressive lenses, computer glasses are also a smart choice because these lenses are typically not ideal for the distance to your computer screen.

To lessen your exposure to potentially dangerous blue light generated by digital gadgets, you may also want to think about using photochromic lenses or lightly tinted lenses for computer eyeglasses. Ask your eye doctor for further information and suggestions.
