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?
