ive never heard of that. it kinda worries me...haha. bc im infront of a computer probably 75% of my day. thats one a boring day. i know i had to get glasses again bc im infront of the computer too much and i was squinting which was straining my eyes.
i've never heard this one either. i know that uv rays go through windows so you should always be aware of incoming light and the effect it can have even while indoors.
but i have no idea about pc screens giving off uv rays...?
