Treating Monitor-Related Eye Strain?

bergeron76 asks: "Like many of you, I look at CRT and LCD displays constantly when I'm at work and when I'm at home (and even when I'm in my car). As a result, I was wondering if any of you have any neat ideas or ways to help reduce eye strain and dryness while looking at displays continuously? I've tried vitamins, eye drops, increased blinking, and combinations of glasses / contacts with little success thus far. People make assumptions about me because my eyes are constantly blood-shot, and I'm wondering what I can do to heal my eyes? I recently heard about Punctum Plugs and was wondering if anyone has had any experience with them and if they're worth the cost. They're little plugs that reduce the size of your tear ducts so your eyes retain more fluid and stay 'lubed'. Does anyone have any experiences with these or have any other recommendations for reducing eye strain and dryness (aside from not computing)?"

    Get your refresh rate on your monitor up as much as is reasonable - even the slightest flicker can cause trouble after a few intense hours.

    Also, if you can, find a way to get rid of fluorescent lighting in your work area. It makes a big difference.

    You may have eye problems because you aren't eating well, aren't fit or don't get enough sleep on a regular basis. My eyes are still recovering from a late night (20 hours awake) - it usually takes a few days. Also note that near the end of your twenties you will find your body doesn't heal from such activities as quickly. If you stay up for more than 16 to 20 hours at a time more than once a week I wouldn't expect you to ever recover.

    But you are talking about two seperate (but related) things - eye strain, and dry eyes. There are two seperate remedies if you have taken care of health, fitness, and sleep. First, look away from the screen at a far away object for 30 seconds or more at least every 10-15 minutes. There are programs which cover the screen and force you to do so for periods of time. Second, make a program that flashes something large on your display every 10-30 seconds extremely briefly. Your eyes will instinctively blink, and you will not be distracted after getting used to it - much less distracting than a beep, or other stimulues, and uses your reflexes so you don't need to take your mind off what you're doing.

    I find that reading and coding cause me to keep my eyes open for far longer than they should be. I would be surprised if you were actually blinking enough when you were trying to blink more frequently.

    My response is going to echo a lot of posters here for this question. These are things you can do while you're (say) writing code.

    First and foremost, don't be afraid to take yourself away from the problem. Side effects: you can sometimes focus more on a problem when you distance yourself from it.

    Second, fluorescent lighting will contribute to the problem. They are HORRIBLE for your eyes. If at all possible, use halogen - it's closer to the sun's lighting than even incandescent. Keep in mind that there is a latent flicker in fluorescent lighting that only becomes very obvious when the bulb or ballast starts to go bad. It will strain your eyes, and no polarized or UV protected lens will stop this. This is why people wind up doing the bifocals thing after years and years in office environments.

    Third, don't be afraid to go outside into the big room. You know, that room outside the installation with the bright blue ceiling during the day, or buncha pinprick lights at night? It's good for you, and...well, see my last paragraph regarding halogen lighting.

      It is rare that productivity actually benefits from a long wide-eyed zombie session. I mean... it does happen, when a large solution comes through and you are so excited to do it that you can't think of anything else anyway. Most of the time, you can keep working productively without your fingers on the keyboard and your eyes on the screen more than maybe 10% of the time.
      Note: If your typing sucks, you'll get less rest time. One day, a friend came by my cube and looked over my shoulder. He apologied, explaining that he was annoyed by my "playing" with the keyboard, thinking that I was just drumming my fingers on the keys, but was surprised to see that it was all accurate text. He said I'd be dead silent for a couple of minutes, then maybe 20 seconds of a sort of "ripping" sound. Spend some time thinking between console sessions. I go maybe 10 minutes, then force myself to stand up. I either do a couple grass pickers, a pushup or two, or take a fastwalk lap around the office. Regardless, I do a few focus shifts - infinity to nosetip and back.
      Here's an setup change for you, though... Get your monitor down as close to desk level as you can. It seems like everybody wants their monitors up high, but unless you're posing for an office products catalog, it forces you to open your eyes wide. That can be disastrous when you're "becoming one with" a screenful of code, and you forget that you're even made of meat. The less of your cornea that's exposed when you're an unblinking zombie, the closer exposed sections are to the wet edge of your eyelids, and capillary action has a fighting chance against evaporation.
      Set up to have the monitor as far away as practicable. I gave up some density for range... 21" monitor, at only 1024x768. It's nice to get more info on the screen at one glance, but rarely necessary.

      The best analogy I can give is to compare how you feel after crouching for an hour versus walking, standing, sitting, and laying down for 8 hours. Let your eyes move around, internally AND externally.
      Oh, and don't plug your tear ducts. You make a place that stays warm and wet, without getting rinsed. Unless you're trying to grow bacteria in your tear ducts, that's not a good thing.

    • Get a high quality monitor
      If you can't get one at work, at least have a good one at home. I went looking for a 19" monitor that could do 1600x1200 four years ago, and while I could have paid $450 (prices in USD), I instead opted for a $600 model (I used pricewatch for these prices). Why? Because any eye care and related discomfort to me wasn't worth $150. And the monitor really should be able to do at least 70Hz at the resolution you use, I can't tell you how many people I know who've had monitor-related headaches that were fixed by upping the refresh rate.
    • Balance your color settings
      I've used Macs for a long time, which come with excellent color-balancing software. But PCs don't have this, and I'll often notice they present an image onscreen that is horribly out of whack. A lot of monitors allow you to adjust the strength of the color outputs, and I assume there's some software to do the same (try Adobe?). You shouldn't notice any adjustment in your eyes between looking at the monitor and the real world (such as if you putting on or taking off tinted glasses). That's not good for your eyes either.
    • Don't sit too close to the monitor
      You're supposed to have your eyes 2 feet from the screen. I don't know anyone who actually does this, but most people are at least 1 foot away. If you're sitting closer, or finding that you often have to lean in to see things (such as small text), you should probably get a larger (physically) monitor, or run at a lower resolution (or, adjust the sizes of how all your fonts display). This will make a big difference, and you'll see results almost immediately.
    • Align your monitor with your eyes
      Your eyes should be even with the top of the screen (not the bevel). Ok, this doesn't have to be precise, but if you are constantly looking down or up it's going to suck for not only your eyes, but your neck and back, too. It's easy to fix, too, mostly people have monitors that are too small, so they stack books or bricks or whatever underneath to raise it up.
    • Eliminate glare
      Almost forgot this one. If you're getting too much glare from windows or overhead lights you're going to be squinting constantly while using your monitor. You probably don't even notice it, as (like all of these things) your eyes just adjust to it automatically and you don't notice until they're bloodshot or you've got headaches. But if you find that you're squinting, get a filter on your monitor, or buy one that has some sort of anti-relectivity technology built-in. Well worth it.
    Ok, that's not going to solve everyone's problems, but it will help. And most of the adjustments you make once, and then forget about. Seriously, you really don't want to cheap out when buying a monitor. $50 more spent on a monitor is going to affect your life significantly more than $50 on any other part of the computer.

    • when you take time to think of your code look out a window or at the farthest possible distance you can in your office. Do this often. I mean very often.

If I drink three Canadian beers one evening I've got blurred vision for two days, fat meals such as French scalloped potatoes do the same as well). As a rule of thumb anything poisonous (nicotine, alcohol, THC) is bad for your vision.
    • use a black background for your code. I find it rests my eyes a lot more than a white one
    • use halogen rather than neon lights and ask to sit by a window to get as much natural light as possible. If they ask you why show them your red eyes.

    She determined that I needed a little bit more power in my mid-range vision, i.e. the range at which a typical computer monitor will be from your eyes. She recommended a prescription with progressive lenses. (Thats the prescription terminology for lenses with invisible tri-focal features. The brand name for most such lenses is 'Varilux'). She prescribed lenses with a very slight amount of additional power in the mid-range focal area.

    She also highly recommended anti-reflective coating on the lenses. (The brand name for the AR coating they use is 'Crizal', from the same company)

Despite the price, I was so happy with those glasses, that when they finally broke a few weeks ago, I went back to the same place and spent roughly the same amount for a new pair.

    I have had 15/20 vision all my life, and I've also been a heavy user of computers since 1979. People ask how the heck I have maintained my eyesight. It is really simple: turn the brightness down!

    Here are my tips for adjusting your computer monitor:

    • Display an image that contains a lot of BLACK, not grey, but black image. A perfect example is your boot loader, like lilo, if it doesn't have graphics. The black background should be black, not a shade of grey. If it is, turn down the brightness on your monitor. That is the dial that usually has a picture of a sun (or a circle with lines coming out from it).
    • Now turn down the contrast all the way. That is the dial with the half-filled circle. Turn it up until you can read the text without straining.
    • Now, if your monitor supports color temperature, adjust it to the 6000 or 6500 setting. This has a bit of a yellowish hue to the white, but you'll appreciate it later.

    That's it. Note that if you are working on computer graphics, this will NOT make the colors bright and pretty, so you'll probably have to go back to the eye-killing settings. But if you're a coder who is just doing text and web browsing all day, USE THIS. Your eyes will thank you for it.

    Even better: do the same thing I mentioned above, but with an LCD screen. CRT monitors are worse for your eyes than LCD.

    If you're playing first person shooters like Quake, you will probably have to crank up the brightness dial. Just remember to turn it back down later!
