Let's put aside harmful affects of staring at computer screen, is there any advantage of looking at computer screen for long time ?

The reason that I ask this question is this: My mother and father both did not use computer when they were young and they had sight has problems when they were around 22-23 years old, and started using eyeglasses.

On the other hand I have been looking at computers since I am 6 years old, I became a computer engineer and my life is looking at computers. Now I am 31 years old and I don't use glasses and don't have any problem with my eyes.

Even though I am genetically prone to, I did not suffer any problems. Could there be a relationship ? Or am I genetically lucky?

    Without having any expertise or conducting research in this area, I'd say no. My parents do have glasses, and so do I, but my vision is a lot better. This is more likely to be the case because myopia et al. is diagnosed earlier and treated earlier, and therefore eyesight doesn't decrease as quickly. I suppose that something similar might be the case with your Szenario as well. Correlation, not causation. – Narusan Aug 9 '17 at 21:38
  • +! for correlation not causation statement. Actually I meant +1 but the ! does appropriately relay my sentiments in seeing you say that, so I'll keep it. – DoctorWhom Aug 10 '17 at 7:08

People who look at computers frequently, (in particular those that look at a computer for more than three hours a day), may experience symptoms such as:

Eye discomfort


Itchy eyes

Dry or watering eyes

Burning sensations

Changes in color perception

Blurred vision

Difficulty focussing

Despite the potential eye problems caused by looking at a screen too frequently, research carried out in the US has actually found that some screen viewing can be of benefit to the eyes.

Specifically, they found that playing video games can improve vision.

This is because playing video games gives the users chance to improve their contrast sensitivity.

Contrast sensitivity refers to how faded an object can be before it is impossible to differentiate it from the same field of view. It is something that is affected by ageing.

Contrast sensitivity is particularly important for activities such as driving in poor visibility, like in fog or at night.
