    Not sure what you mean by computer glasses.

    If you mean eyeglasses to wear while using your computer, you should talk to your eye doctor.

    That said, I have 3 pair of glasses. My regular pair are trifocals for distance, medium and reading. Then I have a pair of prescription sun glasses that are bifocals set for distance and medium. Then my 3rd pair are my "computer glasses and they are set with a focal length that is out to the end of my fingers when I stretch out my arm in front of me - which is right where my monitors sit.

    Yes, I was meaning the eye glasses for computers.

    I don't know if it really needs a doctor to wear them, but I am still confused about all of their 'features'.

    Features? They are just eyeglasses. What features are you talking about?

    Computer glasses (at least the ones I am talking about) are just like reading glasses except they have a focal length of about 24-26 inches where reading glasses are for up close, around 12 inches.

    Maybe you should provide a link to what you are talking about.

    Also note that you can typically buy inexpensive ready-made glasses at your local druggist/pharmacy. But typically, most people who need corrective lens need different prescriptions for each eye. The pre-made glasses you buy at the store have the same correction for each eye. This can lead to eye strain and headaches. So you really should have your eyes checked by a professional. At least then you can get a prescription and maybe then, buy ready-made glasses.

    Your eyes are pretty important and they need to last a long time. Take care of them.

    If you are taking about "Gaming Glasses" the most popular brand (Gunnar) claims such benifits as prevents dry eyes (any non prerscription glasses would do this), and glare,their main claim is they reduce the negative effects of blue light that causes eye strain, "visual stress",and eye fatigue, and increases clarity. These "Gaming Glasses" are so designated for the reason that it is assumed that a lot of gamers spend hours dail looking at brightly colored content. These are the only type of computer glasses I know anything about.

    If you enjoy watching a yellow tinted monitor buy them. They do seem to increase clarity somewhat, however they produce a noticeable heavy yellow tint on viewing the monitor. I have owned a pair of Gunnars for about a year and have worn them approximately 30 minutes total. That yellow tint is unacceptable to me. You can't remove a lot of blue from an RGB color setting and have an accurate color.

    Non Gaming glasses are designed to put the optimum lens power for viewing your computer screen right where you need it for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures.

    That article is a good read. Thanks.

    I think it important to note even those Gunnar computer glasses require a prescription. And the article does emphasis having your eyes professionally checked.

    As for anti-reflective coating, I have that on my sunglasses and it is great for driving or just being outside. But they are horrible for viewing any sort of LCD display screen like a cell phone, ATM, cash register PIN pad or even my computer monitors. It makes it seem like I am looking through a layer of oil or something - often totally obscuring any text.

    And yeah, I would not want any glasses that filter out any colors - no matter how slight. I guess if all you did was look at text all day, that would be fine. But computer tasks tend to be very graphics oriented. We buy monitors to display "true colors". "Color accuracy" is a quality we look for when buying monitors. It seems counter productive to me to wear a lens over our eyes that distorts those colors. But, to each his own, I guess.

    Gunnar also sells non-prescription versions of their gaming glasses at stores such as Best Buy. But yes, they also make prescription glasses also.

    Good point. I was not thinking of non-prescription. Except for sunglasses, 3D glasses, or safety glasses, non-prescription glasses are not something that comes to mind - at least not for me. Thanks.

    I have Computer Glasses via a Prescription from an Optometrist and it's much better on the eyes as it has Anti-reflective coating as well. Most of the middle is for Computer and a bit at the bottom for reading and the top is normal but others might need a bit of distance or whatever.

    Well I don't feel alone anymore, I'm set up about the same way. :argh: Except for the trifocals, didn't get there yet. I'll give it a few years before I do. I remember when I was young may years ago and didn't need glasses.
    Now we are all showing our age on the thread. :argh: :argh:

    Yeah, technically, I don't need glasses for distance (or driving). But I have a slight astigmatism so that correction is there for distance. I had better than normal vision until I was about 35. I probably needed glasses for reading and up-close work by the time I was forty, but my ego/vanity refused to admit it until I was 45. Now, nearly 20 years later, I have to wear my glasses for anything closer than 6-8 feet.

    Not to run this off topic further, but my sister wore glasses most of her life. Then when she was about 50, she had the surgery done on both eyes. But fascinating (to me anyway) was one eye was corrected for distance, and the other eye for up-close. It took about two weeks to train her brain to reprogram itself to automatically switch and set the specific eye as the "dominant eye", depending on if she was looking at a distant object, or something up close. The brain's a funny thing.

    Yes, go to a qualified optician.
    Explain to them your usage pattern for display devices, get an eye test.

    Also don't underestimate how much a good quality CALIBRATED display helps, as well as take recommended breaks away from the screen.

    I think this a problem these days. People see brand new 24" monitors going for $110 with a decent 3 year warranty, then wonder why they should spend more?

    I say if you are going to be staring at something for hours per day up to 7 days a week for nearly 365 day a year, do your eyes a favor and buy a quality display.

    The eye glasses will become important to us when we get older. I myself am lucky that i still don't need any for my computer monitor. Going out yes to see far and also when shopping to get a receipt to know what i have payed, the slide multifocals or what they are called are good. Not bifocals, they are a nuisance.

    But for reading, looking at computer if needed, I suggest only a lense that is optimum for that distance, well a 4-5 inch phone display might also work with multifocals. But for general reading we need simple lenses. "1 power only".
    My advice.

    I note that article is over 7 years ago. I believe current research suggests extended use can damage your eyes and cause other visual problems - if necessary precautions are not taken. So I believe a game "designed" to improve peripheral vision may help, but not sure it is safe to say "in general", computer games help with such improvement.

    Yes the current LED light technology. Some blue light radiation on displays or them light bulbs might be harmful to eyes. My new display has some IPS thing that is supposed to reduce that. I did not know if some glasses existed to filter that?
