The "dont sit close to the TV," thing is objectively truth and is even worse today.

I used screens a lot growing up, including a laptop and various portable games like the Gameboy and PSP

This led to my eyes slowly developing the need for prism on my lenses, because they over-correct now focusing on close objects.

Nowadays smart phones are this problem but way worse too, if you sit in the dark holding it way too close, especially with glasses on, you are slowly deteriorating your eye muscles.

Unless you exercise them of course, every 20-30min. But most people dont do that.

I now am having to do constant daily exercises to slowly undo my prism, a year and a half ago I had a prism of 5.0 on each eye, this month I finally got it down to 2.5, which is solid progress!

However VR doesnt have this issue, its a virtual image that appears to be 2 to 10 or more meters away, so your eyes are focusing like looking at something far away.

    It's not objective if you're only citing personal experience, though. I've been sitting up close to monitors for almost 30 years now, and my sight is as good as it ever was, except for my left eye seeing slightly worse from that one time I actually did go outside and some dumb kid threw a brick in my face.

    Used to be as people got older and their lenses lost flexibility they'd develop farsightedness (presbyopia) and need reading glasses, now it's common to become shortsighted instead, due to screens. VR may help, or at least let you choose your own adventure.

    Prism is neither near nor far sighted issues.

    Prism is a muscle problem, where the actual muscles of your eyes get weaker because you arent using them as often to focus on objects far away, so they lose flexibility.

    Akin to how if you sit in a chair all day and arent actively stretching purposefully, you lose flexibility in the rest of your body too.

    As far as I know, focusing on objects has no impact on eye shape changes, its just genetic on which way your eyes start to squish/stretch as you get older. Thats just a byproduct of the fact our face and tissues change as we get older.
