Hi,

My eyes often get hurt and red. I want to protect them, how? I have a 60 Hz LCD 22" Wide I cant make Hz any higher. I'm trying to sit as far as possible, I tried dropping brightness and contrast. What now? I'm sitting only like 5 hours in a row.

[Vikingod]

Do you have trouble with all LCD monitors or just this one?

It might be the monitor itself. I've had similar troubles with one specific monitor (it was giving me headaches, eye trouble, dizzyness, etc.). Once it was replaced, I've not had any trouble since. You may also want to check the lights in the room in which your computer is located, especially if they are fluorescent.

Then again, it might have nothing to do with the monitor at all. Five hours in front of a screen can be hard on many people.

Well I never heard that LCD's would cause this. It's more CRT users problem. I got two LCD's both @ 60Hz and I don't get any problems. But they are connected via DVI-I cable to the gfx card. But the best solution to your problem would be natural... Like going out with your mates to see the Girls in Lahti... I know that there are some nice girls out there

Ahahah, yea sure.. I recently met one nice girl

But I am a coder and I don't like the fact that a couple of hours hurt my eyes... but surely the best thing to do is to let eyes rest...

Are there widescreen LCDs with >60 Hz?

Nice to hear, do spent some more time with her

Not all of them are. Some screens can do 75Hz. Anyway what connector you are using and what is the monitor model?

DVI cable. ASUS 22 LCD VW222U is the monitor.

[temeteus82]

Hmm... Now it sounds like that problem would be some where else than in the monitor. You don't get the same thing from any other activities?!

It's just sounds that your eyes are getting dry from the coding stuff...

Yeah... I guess so, they are betraying me.

i agree, i have the same problem... except that i have a CRT monitor... i don't like LCD or TFT monitors... but i don't sit in front of the PC more than a few hours, at least i try to...

i do wear glasses... so i bought a pair of glasses with a CRT radiation filter, and let me tell you kaisellgren... they are great . if your vision is just fine, you could get ones with no diopter... just plain simple plexiglass ... yes, the lens are plastic... no glass . i guess it could work with LCD monitors too... or you could downgarade your LCD monitor to a CRT one and get the glasses, that way you will know that they will work for sure... hahahahahha

believe me, i know the frustration you are going through, i'm an electronics and telecomunications engeneering student (still have some exams left...), and most of my work is with simulation programs or PCB editors (like OrCAD, Matlab, Protel), so i spend most of the working time in fornt of the PC, so the advice above is the best one i could give you...

Try taking breaks more often and some basic non-prescription eyedrops, especially now during winter when the air is dry. But the only common problem with LCD's is that many are unnecessarily bright at the full brightness level that they are shipped with. The 60Hz is not a problem because there's still no flicker like on tube monitors, unless the LCD panel is damaged. The lighting around the workstation is also important. Perhaps even the desktops visual theme/color scheme isn't helping either.

[Mousey]

Have you tried wearing sunglasses? Really odd suggestion i know but i've got a 30" CRT at the end of my bed with a pretty low refresh rate and a late night gaming binge hurts my eyes usually unless i wear sunglasses then i'm fine.
Give it a shot before you go buying anything else

[craig5320]

You could be suffering eye strain, it can take weeks and weeks to heal, and if you continue using screens for that length of time it probably won't go away.

I was having eye problems but after a few weeks of taking regular breaks it eased off, aim for at least 5 minutes in every hour or something.

[BlueMak]

If you use monitors a lot, especialy CRT monitors, don't forget to drink milk every day.

You might want to see a eye doctor, you might have a dry eye condition, very common.

[Judas]

Do you blink often enough?


LCDs are one of the best if not currently the best solution on the planet that is the easiest on ones eyes....

The reason for this is by the way they work, with smooth transitions from one shade or color to another, unlike CRTs and even Plasma displays that essentially "strobe" light at you.

The hz doesn't matter really.

Now the only reason you would get eyestrain is:

a: The resolution is possibly to high which is causing you to put effort into seeing what it on the screen. Obviously this would suggest your to far away, or are in need of glasses.

b: Perhaps the games your playing are running below the acceptible frame rate causing stuttering which has usually nothing to do with the monitor, but the capabilities of the computer your using. Video card or other parts could be affecting your frame rates, perhaps even the settings of the game or video you playing. See if you can adjust things to better suit what it's capable of.

c: Running anything at the non-native resolution of your LCD? I've come across a number of people that said they were getting headaches or eyestrain, only to find out because they were staring at a fuzzy out of focus or not quite right display, the reason being they were running at none native resolution.

d: Do you blink often, it's been a known case that a considerable amount of eyestrain or headaches can be caused by simply not blinking often enough. Now you'd think this is one of those cases where you should automatically blink. But it doesn't, people have gone many minutes without batting an eye, specially playing games or watching videos, this happens more often then some people will even realize. It's worth paying attention to yourself while doing this, and forcefully blinking..... sounds weird, yes.

e: Vsync, it's worth it, even on lcds, and you CAN still get "tearing" specially noticable on the faster responce time lcds that are becoming more and more like CRTs..... turn it on and see if it improves anything while playing games.

f: While it's typically unlikely to be the case, it's possible, and it's been stated so already. The monitor could be the root cause, not the lcd tech specifically, but the monitor. Not much can be suggested other then to "try" another one if you can manage that somehow.



just a Fyi,

60hz is the lcd standard, there isn't any monitors that i'm aware of that runs 75hz or higher natively (excluding the 120hz and 240hz models)

How does milk help? Sounds like a myth to me...

No I have not tried sunglasses, I'll give them a try

I don't take breaks, but I do try to watch elsewhere every now and then. Like when my PC is loading something, I'll watch somewhere else.

Maybe I am not blinking enough often :O I'll try to force myself to blink from now on and let's see if it helps. I also set my monitor to use less brightness and contrast, I'm running at native 1680x1050 resolution and the monitor is roughly one and half hand away from my head. Sometimes I get closer and it's one hand away.

And I do have backlights on my room. Full lights everywhere, desktop lamp, four ceiling lamps.

I'll guess I'll have to get my eyes more wet, blink more often and take small breaks every now and then. I'll also try to use some glasses, but my vision is almost excellent. I can see far and near.

[Judas]

i'd also like to mention that the "correct" position is to be sitting where your eyes were to be even with the top 1/4 of the monitor (this would basically cause you to look slightly down at the monitor)... this could release a little stress as well.

As for sitting distance, it shouldn't matter ALL that much.. but typically at least a foot away is normal... Course i've seen some people sit no more then 4 inches away.....

[BlueMak]

Milk doesn't have anything to do with your particular problem. Milk is good for you and you should drink it.
Also, it sort of helps against radiation or something, but I don't know the details. So, in conclusion, milk is good, drink it.

[Zelig]

Like some other guys mentioned, take some breaks, walk around and do some push-ups or something, sitting for 5 hours straight staring at a light isn't healthy.

For reference, there are very few monitors that operate at 75 Hz properly. Using DVI, no monitors operate at 75 Hz, and even over VGA, with 75 Hz set in the OS, most monitors tend to just skip the extra frames.

I had a good link for this, but can't seem to find it atm...

Use larger fonts and increase viewing distance.

Hz definitely does not matter, as LCD is buffered.

Do not use a stippled background or colour, as the matrix architecture of LCD can produce some odd effects. It may be best to keep to 24/32 bit colour, as even the quantization to 16 bit can prodice visible artifacts.

Redo the LCD autoset, to ensure it is well matched to the signal.

Get the Cleartype tuner, if Cleartype is in use and set for the wrong alignment (BGR versus RGB) then it makes the text fuzzy, rather than clearer.

[Dyre Straits]

After I get some hefty bills paid off [medical, auto repairs, etc] I want to invest in a nice LCD monitor for myself.

How much does the ms response time have to do with eye strain? If any?

Thanks. I'll take your advice. I setuped 120 DPI in Vista Personalization window and I applied RGB Cleartype with TuneUp Utilities. I'll also try to take some breaks. I've been out from the PC for roughly 24 hours and now my eyes are fine except for some minor reddish.

I'm also interested in this.

from what i can tell.... even with the heavy ghosting of lcd monitors... it didn't give much of any eyestrain....

values below 16ms has always been preferred though.

but some of the best monitors quality wise are down in the 2-6ms range now... which is lightning fast.... faster then what 60hz would need.

actually i think it's 4ms where 120hz will work... the newer displays they are designing are sub 1ms for 240hz (it's coming)... 2010ish perhaps will be when those displays arrive.... I think most companies are skipping 120hz for our current standard monitors due to the lack of support for higher frequency capabilities of current dvi and i think the initial design of display port....

[dawgXdenta]

Point well noted lads

[kaisellgren]

I actually solved the problem

I didn't understand why I was suffering from eyes being hurt. I have my PC on the table right next to me and I have three case fans (fast ones) blowing dry hot air right into my eyes and that made my eyes go bone dry really fast and my eyes started to hurt. I have now moved my PC under the table and everything has been cool so far

[mkk]

That will do it. It's probably quieter from down there too. Just sweep the floor from dust now and then.

[Robert McClelland]

I have View Sonic 1932w LCD HDTV I have no issue with my PC HDMI cable hook up to it and mine always at 60 Plus I watch tv with my HDMI from my direc tv with my 3way sitch hehe. no issue with eyes at all.
How man m secs is it? mine is 5m Maybe yours is like 3 or something?

Nail hit on head.

The air blowing has got to have been a revelation too - that must have been most of it for you though. Do you have any allergies?

[Robert McClelland]

Or it could be dry in your room do you have humidifier?

[kaisellgren]

My last post explains the issue, I solved it

[Kizo]

As a suggestion to a fellow programmer ( or coder, as you wish )... black background, with grey and custom colored code make all the difference. (at least they did for me)

I made that modification when I started programming several years ago, when I noticed my eyes were getting tired after several hours of work, and found that it is much better for them. Never changed back to white background.

Cheers
