I have had my new 3DS since Christmas and I've been playing on it for like 2hrs a day since on mario 3d land. But recently i started getting this problem. Every time I play on super mario 3d land on my 3DS for an hour or two with the full 3d effect on. My eyes seem fine while playing, but when i turn it off and i find something else to do like go on my pc and start browsing the web, every page i look at my eyes are still trying to adjust and everything i see on my monitor looks like 3D mode still! This problem lasts for at least an hour or two after play. Should i go to the doctors and explain to him or should i just stop playing my new 3DS because the last thing i want is permanent eye damage.
