Monitors for People with Poor Eyesight? 258
tuxbeej writes "Just recently I've been told that I may be developing keratoconus, a non-inflammatory eye condition in which the normally round dome-shaped cornea progressively thins causing a cone-like bulge to develop (thanks, NKCF!). As a result, my eyesight will get worse and it's getting harder to see on a 15" monitor. Being 22 years old and studying MIS, I've been hoping to keep my eyesight for a long, long time. Anyway, I was in the market for a new monitor and I was curious to know if anyone has done shopping for a monitor intended for someone with bad eyesight? Are there any recommended sizes, features, brands? It seems like a generic question, but I'm curious to know if certain technologies have any advantages over another or if there is a site out there that handles info like this." We had an older article about CRT's vs. LCD's.

The flatness of the monitor works very well, since it cuts down on glare. And the nice size of the monitor lets you put some distance between you and it. If you run that big bugger in 1280x1024, you'll be doing fine.
Make sure you don't use the monitor in a darkened room often, that'll cause you problems, and if you wear glasses, it has a pretty good chance of giving you a headache. And if you sit near a window, you might want to get an anti-glare screen. Having bright spots, (either the monitor in a dark room, or glare on the screen) can cost you some vision, given enough time.

Do not be tempted to just run your video at low resolution. I would instead suggest running at a higher resolution, and use better fonts at a larger scale to read; this way they won't look so ragged. Also, anti-aliased fonts might be easier to look at as well.

go for at least 19" and use 1280x1024 res... 21" would probably be better if you can afford it. I seem to be able to read better off my laptop if the text is antialiased properly (a big "if" on linux, unfortunately--the new kde is awesome for this), but i haven't had the chance to compare to a flat-panel monitor that was worth a shit. I think part of the laptop's appeal (aside from portability) is that the screen is much easier to tilt and has a wider range.

I first tried hard contacts (to try to flatten the cornea) but just couldn't handle them, so I've stuck to glasses. I'm going to get a new perscription after I move (next month), after 4 years I definately need them. In my case at least having a lot of light helps.

i have found the website http://www.surgicaleyes.org to be a good (although somewhat scary) source of info for all sorts of visually-impaired folks - ranging from surgically-induced blindness to keratoconus to corneal transplants.
check out the site - and the bulletin board - and dig around for some links on keratoconus sites and PK (corneal transplant) information.
there is a consensus that keratoconus can be put-off with a good pair of Rigid Gas-Permeable Contacts for quite some time.
also keep in mind you will bump into information about up-and-coming treatments for keratoconus - things like Keraform (an enzyme being developed to re-shape the myopic cornea) and other strange stuff.
anyhow, check it out (and dig around on their message board for strings like 'keratoconus' as well)
good luck!
(and by the way, i'm using RGP contacts to help read a 21" monitor set to about 1280x1024 - so don't rule out the well-fitted contact lens solution!)

Kerataconus (Score:4, Informative)
Anyway, since the transplant I have had to make adjustments to my computer using environment in order to keep my eyes sane - the single biggest improvement is using really, really big fonts that are anti-aliased. For some reason, I've also found that varying the hue of things (dark green text against beige backgrounds, etc) seems to make things easier to read. Also, though I'm sure this won't be an entirely popular suggestion, ever since I switched to Mac OSX from Linux, my eyes have improved dramatically. I have attributed it to the entirely antialiased environment, but it could easily be coincidence.
Good luck.
PS. The good news is that cornea transplants are among the most successful of transplant operations, with an average success rate of 92%. (should you need one).

Brightness adjustment is important, too! (Score:5, Informative)
I can't stand when people crank the brightness control up all the way on their monitors, thinking "brighter is better".
To get the maximum clarity and contrast possible with a given monitor, I recommend turning up the contrast control to around 100%. (Some monitors will draw small fonts a bit too thick or blocky like this. If so, back it off to 95% or even 90%, but probably not any lower than that.)
Then, when you have an image on your screen, you want to turn down the brightness control just far enough so the border around the image appears to be black/not lit up at all.
This combination should be much easier on the eyes. (Especially important when you're at the command line on a full screen text mode, where there's lots of black background.)

I've got the same condition the article submitter has. With KC the treatments are either rigid contact lenses or cornea replacement surgery. Obviously the former is preferable to the later. (I actually got lucky and dont need any treatment yet). Glasses wont do a thing and you'll end up changing your prescription every other month.
Lots of good information (including a great forum) at www.kcenter.org [kcenter.org] but of course take everything you read online with a pinch of salt
Things to try (Score:2, Informative)
Figure out just how far you sit from the monitor. Ask your ophthamologist to write you a prescription for glasses optimized for that distance. Explain exactly what you're using them for; he may have a better idea of what to use.
If you're having problems with chromatic aberation, which shows up as red, green, and blue colored bands around letters, get a monochrome monitor. It isn't enough to set your software to display in black and white; this has to be done in hardware.
Get a big monitor. You may want to run it at a lower resolution than it's rated for. This is especially true if you have a hard time seeing thin lines. Many programs will insist on using one-pixel thick lines; it helps if the pixels themselves are larger.
Good luck!

Me too... My specialist told me that the rigid contacts dont actually flatten the cornea as such (which is what I thought too) but rather combine with the cornea and the tear fluid inbetween to act as a sort of super-cornea
Luckily I dont contact lenses at all yet (the cone caused by the KC is below the center of my cornea and so doesn't affect my vision yet).

My interest here is *not* in asking people for medical advice - that's why we have doctors. I wanted to find out if anyone had seen studies or had suggestions for display technologies that would be easier on my eyes. Since I had not found anything on my own, I posted the question here, since I believed there's probably a lot of people in the tech community who are young, have bad eyesight, and are seeking the same kind of solutions I am.
You're aboslutely right, though - don't take any medical advice from a forum. Always take that advice to your doctor and get their opinion. Then get *another* opinion. Especially when it comes to your eyes. We only get two, and we don't get any more.

To the original poster: As for advice on monitors...well, first I'd suggest checking with your optomitrist, as several others have said. They're best equipped to tell you at least how to avoid things that could strain or damage your eyes more than neccesary. Beyond that, I'm not sure how much advice I can give you, since I don't suffer from your particular condition.
Personally, I suffer from pretty serious nearsightedness. I'm not legally blind, but my vision is pretty bad without glasses. Anything up to a foot away is fine, after that, it degrades pretty quickly. I can read my jumbo alarm clock from across the room if I squint right. At work, I wear glasses when on the computer, but at home, I usually do without and just sit closer to the screen. Eyestrain has never been a problem for me...dunno why, though.

Another oddity I've noticed is that I cannot stand dark screens. Most people I know like darker screens and say that brighter monitors make their eyes hurt. I've always been the opposite way; dim monitors give me a headache, but bright ones are just fine. Go figure...

1. Lighting is VERY important. make sure you have ambient light.
2. the size of the monitor is also very important, but CRISPNESS is more important. You must make sure that the monitor is CRISP. You cannot really tell if a monitor is CRISP without looking at it. Two monitors with the same pitch distance can be very different when you actually look at them.
3. You MUST get them with full 3 year warranty. Monitors are so fragile, that it may be already broken during shipment, before you open the box. Monitors, especially big ones, have an extremely high lemon rate. If you spend money on a monitor and you are not satisfied with the image quality, insist on taking it back. You must move it *very* carefully.
4. LCD vs. CRT. Well. LCD technology is simply not there yet. When IBM shows me the 300dpi monitor I'll take a close look and maybe change my mind. The truth is, For the price you pay for a LCD with high quality digital signals, you'd be so better off with two beautiful 20" high end monitor. Another thing is, in Linux, you can configure 10 different resolutions, all the way from 1200x1600 to 400x600. LCDs cannot scale good. When a LCD is displaying any size that is different from it's own, it interpolates. This anti-aliasing kills your eyes because your eyes tend to think that it is out of focus.
5. Video card counts. You must get a Matrox. Make damn sure that it doesn't get under 85MHz. Better get higher rates. Hand tune your monitor carefully.
6. Monitor cables counts a lot, too. Best is high quality BNC cables, they are about $100.
7. Do yourself a favour, use OPERA as your browser. you can zoom in any size you want with your numeric keypad. Right now I'm typing in half-inch letters.
8. one thing great about two huge monitors is that you can set one of them at really low resolution, so when you switch to windows. *shame* like VC++ you can see BIG letters.
9. Picking a monitor is likely shopping for fruit. You must hand pick yours. Even the exact same model have different crispness. Pick a good one.

My school have 20" Trinitron monitors everywhere, but they tire my eyes. If you set up your monitor configuration correctly, you are not likely to be tired for a long long time.

I'll bite.As a M.D., heavy computer user, and having gone through eye surgery myself, I've put a lot of reading into precisely this. I get this kind of question asked on a daily basis.
Short version: This is false. Monitors do not worsen your eyesight.
Long version: Computer display devices do not have, and they are not, light bulbs. LCD displays carry a small fluorescent tube to provide backlighting. In a CRT, as probably allThere are, however, certain things that can give you the idea that your eyesight's getting worse. Your eyes naturally focus at infinity, which means that the muscles which stretch the lens for focusing rest when you look at a far-off point (20 feet away or more).
As you grow older (and I mean from 15 years on), the lens becomes more and more rigid, and your focusing muscles must work harder to focus nearer. Ultimately, you just can not focus close enough to read (which is a normal condition) and must wear eyeglasses to do it (at 50 yrs approx).
This means that, as time goes by, you have to strain more and more to look at the screen, will see it blurry from time to time when your muscles get tired and can't focus properly (and yes, they do get tired), and might get headaches from the effort expended.
Is this is the case, an optometrist can provide eyeglasses to look at the screen with your eyes focused at infinity. Sitting farther from the computer will also help.
