After playing with it for around an hour and turning it off my vision feels really blurry and I don't feel my eyes focus all that well.

In a few minutes they seem to go back to normal, but still kinda strange to me.

Anyone else?

Out of curiosity, what have you been playing? Also, could it be that you're not used to focusing up close for long periods? (Like, do you play other handhelds)

Haven't had any problems myself, but trying to play Super Stardust Delta while lying down is really disorienting.

no, no problems at all

Lumines, Katamari.

Guess I'm the only one, maybe I'm getting too old.

I actualy have " gaming glasses" that i use for handhelds. you should look into that, or just glasses in general

Nope. Hell, coming off of the 3DS my vision has probably gotten significantly better over the last week.

@Evil_Alaska: I've been wondering the same thing after I felt sharp pain in my left eye. It happened suddenly and went away after 5 seconds. I use an iPhone and a 3DS all the time, but I've never experienced something like this before.

@Evil_Alaska: That's all I've been playing. I haven't had any issues with the Vita itself, but sometimes my eyes do get tired in the way you're describing. It's probably just old age...:C

Haven't experienced that.

I noticed some more eye tiredness from looking at a screen all day long. I am at a computer a work, computer at home, and vita in between. It's simply hard on the eyes. Also, focusing on something up close and bright is normal to cause your eyes to have to adjust back to normal afterward.

I'm pushing 40, and this has started to happen to me in the last couple years, with just about any mobile device. I find it's more acute with high DPI displays, e.g. recent Androids, iPhones, and the Vita.

Nope. I had troubles getting used to the 3DS but I've been fine with my Vita.

This happens with my 3ds, but not the vita.

This happens whenever I play any portable for a lengthy amount of time. Happened with my PSP, DS, DSiXL, 3DS, iPod Touch, and now my Vita. Also happens if I read things on my cel phone for too long. I assume it's just my eyes focusing up close and getting used to it. It goes away after about 5-10 minutes for me.

@Evil_Alaska: You should check your eyes, I started to have the same problems with my PC screen.. next thing I know: I'm using glasses

That exact thing happens to me if I play a handheld for an extended session without my glasses on. With the glasses on, though, I don't have any issues.

Sorry for kicking up a dead thread, but my husband just got a Vita and this happens whenever I play Katamari. It isn't that I'm not used to handhelds (my 3ds has never given me problems), I can use my phone or tablet to excess and this never happens, and I send a fair amount of time on computers for work with no issue. It's just the Vita. Is the display just that different?

I've had zero issues with this. I did notice that I would get slight eye strain when doing 3D for certain titles on the 3DS but that's about it in regards to issues with mobile gaming.

Played countless hours on the Vita and I never encountered this issue.

No, of course not. I have 20/15 vision. My hands do cramp up a bit after an hour or two since the damn thing seems is made for tiny Japanese hands.
