When the pandemic of 2019 COVID hit, the case report of Computer vision Syndrome saw actual hype. There is a difference between compulsion and desire. It's someone's duty to be on screen and someone’s time passes. The time limit is often the lid you need to put on your social media consumption, if you do it on purpose. 

How younger generation report more eye strain? 

Teens, children, and even young adults these days have Nomophobia, which denotes No mobile phobia, where they feel anxious without the phone. Instagram screen time gets as long as 12 hours in an individual which is insanely too much even 1 or 2 hours is enough to see through the feed,

What actually happens in Computer Vision Syndrome (CVS)? 

Computer vision symptoms are more about the discomfort you feel in your eyes for longer on the screen you have. If you continuously focus on blue light, glares, and computer screens, you need to squint to focus. 

There are chances you see sudden blurred vision out of nowhere, the contrast becomes poor, and one image merges with another, ” 

“It is pretty annoying when my eyes hurt to even blink or focus. I feel it's not serious, it goes automatically, but until I rest completely this worsens,”  adds one of the patient at Vision Concern Clinic. 

“I feel like the contrast becomes poor, one image merges with another, like when I watch a movie, the red light of the lamp superimpose on the character’s eyes, I see like burning flame and when I blink 2- 3 times, I no longer see that. ”

Our doctors respond that it is likely to happen, as eyes naturally dry, as usual, you watch the movie without a blink or are so obliged to fulfill deadlines. Because you forget to take a second for yourself. 

The symptoms do not end here. Sometimes,  you feel dizzy, and fatigued like your head is not in pain, pain located between the eyes. Even though you may feel a sudden sharp pain in the neck and shoulder, they go after you take a rest. It's different from a muscle strain. 

Individuals also get visual disturbances if screen time continues and they ignore symptoms. It is essential to have a good posture too when working on a computer screen, so that there are fewer issues in your health. 

Tip no 1: Follow the 20-20-20 Rule

How much time do you spend on screen? The more you engage on screen your chances of eye strain is there. That's known as computer vision syndrome in medical terms. 

When you are only a few feet away from digital devices, this can in fact tax our eye muscles and cause pressure between our eyes. This can cause pressure in the forehead and also cause shoulder and back pain, with the sitting posture and eye strain thing. 

Our eye muscles cramp up when they are put on exercise for a long time to focus on a computer screen or mobile. This phenomenon of cramps in eye muscles is called an accommodative spasm. 

To help prevent eye strain, we take a 20-second break after 20 minutes of screen exposure and focus on the object 20 feet away from the device. That’s the 20-20-20 rule (20 seconds, 20 minutes, and 20 feet). Here’s how you can do it, 

• Set alarms or indicators of your break to give your eye a rest. 
• Shift your focus to the object and watch it for 20 seconds to regain focus. 
• Stay hydrated, take a water break, and reduce fatigue in your body. 
• Stand up, stretch, and walk around every hour

On top of that, eye refocus is a key factor to help you prevent the chances of developing dry eyes. Try to blink your eyes frequently as much as you can. Even a 15-minute break after two hours of continuous computer use is suggested. 

Tip no 2: Adjust your screen position and settings 

Position matters when we tilt our screen, this can cause the glare intensity to increase or decrease throughout exposure. Make sure how your computer screen is tilted to adjust the right direction

There are symptoms of physical discomfort like aching or burning sensation in the eyes that follow with a headache. Sometimes your neck and shoulder may show tantrums, but above all, you need to be mindful of your screen time.  

Will just adjusting our screen help you prevent eye strain? 

My friend, there are many causes, like refractive error, prolonged exposure to bright light or glare, and looking at digital screens for hours, that cause eye strain. Among those, if you adjust your screen, you can only prevent the symptoms from developing in your routine office job or habit of excessive screen use. 

Without a pause or rest, your eyes are to suffer. Looking hours in a row at the same focus on screens is a real trouble, if not taken care of early. You feel unpleasant. In fact, the poor contrast of the computer screen is cruel to your eyes. 

When watching a movie or playing a video game, have the screen at your eye level. The Middle of the screen is where you should be looking rather than the edges. Squint your eyes to focus, you dont want that so, blink about 20 times a minute.

What ergonomic Screen Placement can I do to stop eye and back strain? 

• Place the monitor at arm’s length in an ideal location to eliminate the reflected glare.
• Glare and bright light behind your screen worsen the symptoms, so adjust at the right angle. 
• The top line of the monitor shall be slightly bent at eye level at an acute angle (up to 30° at max.) 

Tip no 3: Wear Protective Glasses (blue light-blocking) on extensive time on screen

The whole process impacts the body’s internal clock, which is known as natural circadian rhythms. Meanwhile, those who scroll close to bedtime have more trouble sleeping and eye strain, unlike daytime users.
