| ...recently i brought Luxor for my PSP, and i really like that game...however, after playing it for about 45 minutes, i notice that my right eye went out of focus a bit so i see blurry image instead of normal...i never had any issues with my eyes, so i drop PSP and leave it for a while and my eye came back to normal for about 10 minutes...i tried again, for purpose of testing, and same thing happen again....now i got curious, since thats happening only when i play Luxor on PSP, everything else is just fine...so...i asked my gf Yoshi to give it a try, and poop...she got same thing as i did...then we asked her bro, he got same thing...im wondering whats that thing? Have you guys ever had such thing? Or it is some weird color phenomena with Luxor and all colored balls around in motion? |
| i get the same problem when i play games for 5+ hours in a row. |
| I sometimes get that, among other things, when I stay up for 36+ hrs. |
| Never had a problem like that. However, I can adjust the focus of my eyes very easily- helps when nearby fat or ugly people. |
| I haven't experienced that with games but if I spend an hour or more taking lots of photographs with an SLR camera, one of my eyes sometimes ends up out of focus for a while from squinting into the viewfinder.|
Slightly off-topic but I've also noticed that if you wear 3D anaglyph (red/cyan) glasses for a long time, your brain (knowing that the colour information from each eye should be the same) actually starts to 'correct' the colours. When you take off the glasses, your view through the eye that had the blue filter in front of it has a red cast and vice versa with the other eye. So I guess if you spent some time wearing the glasses upside down, when you took them off you might be able to see anaglyph images in 3d with the naked eye for a while. I don't recommend trying it though.
| the guy afaik only known as "3D" from back to the future must have had one hell of a headf**k each scene break|
derek jacobi in twin peaks had red/blue tinted glasses but a wearer of tinted glasses myself just cos they look as dark on the outside as 3d glasses dont mean they are going to be as dark looking out
id love to have a pair just to see how real an assumption that really is
mine are sort of an opaque black/brown but white is still white just a bit dimmer
my brother had blue (more cyan) tints i couldnt wear them as i had a different pescription but although blurry the world wasnt cast in a cyan tint ... he was colour blind though so god knows what he saw :))
i found wearing my "going out" glasses at work was handy as i was nigh on eyeball level to a strip light for most of the working day and it kinda difused it somewhat
i can cycle safely in the dark wearing them as i no longer wear 'normal' glasses
but i do get the "it aint sunny enough for shades" comments ... and these have no uv coating no matter how much like sun glasses they look
and no i dont think ive f**ked up my vision even more by wearing them ... im almost blind without em (ok a stretch) but its safer for me to wear em than not at all

my dad used to wear an eye patch for long term camera use* ... i found it hard keeping the other eye closed and without my glasses on the open other eye would be too out of focus to really help trying to focus with my short sighted camera eye
tis another reason why i use the lcd for framing on my digital slr-esque camera how can you tell its in focus when the eye your looking through is naturally out of focus and glasses get in the way
*this also came in handy for snipers he told me
but when removed the patched eye would be ultra light sensitive comared to the normal one
but when removed the patched eye would be ultra light sensitive comared to the normal oneThis happens to me when I wear my eyepatch. Sure confused me the first time.
| I sometimes (fairly rarely) get this phenomena when i have been coding the whole night straight and am tired the next day. Both eyes go out of focus until i shake my head and it goes away. Only happens when i am thinking of something else (daydreaming on the job) |
| I think it's fairly well documented that you should take a break from a screen every hour or so. I would suspect the PSP thing is probably due to it being a small screen and focussing on a small object for 45 minutes straight.|
Anyway, for you own health, I would suggest taking a break from the screen more often.
| D4NM4N: Same here, but I'm less tired now and healthier and it happens less. |
| It's possible to screw up your vision by doing any sort of repetitive task, sitting at a PC screen is bad simply because your eyes are focusing up close for long periods. After a day's coding I often have blurry vision if I happen to drive, for about 5 mins till my eyes get used to long range again. Reading a book is just as bad, if not slightly worse.|
It's of no surprise the nerdy book worm stereotype who is wearing glasses and the overweight truck driver who isn't wearing glasses. Driving for long periods is great exercise for your eyes, continually focusing on traffic at different lengths and directions, speedometer etc, lots of flexing for your eye lense muscles constantly.
(Of course not good for the waist though sitting for long periods and eating convenience foods out on the road)
I recommend setting your computer up near a window, preferable so you can move your eyes around your monitor and look into the street/back garden easily. That way you can continually be looking outside like say when your code is compiling or when something flashes past. Good eye exercise without needing to take a break. I like to look down the corridor or the posters at the other end of my room.
Sure it's a bit of distraction but what's more important a bit of loss of work, or your eye sight?
