Computer Screen

[Rich H]

I'm not sure about if it should go here, but I have had a couple of migraines recently, could it be anything to do with the monitor? I do spend quite a lot of time on the computer after all.
It's a 19inch in size, and I think I'm running it at 75Hz?

First question - do you wear glasses?

Interesting thread. I am near sighted and I cannot read a document on paper at 20 inches without using my bifocal glasses. But I cannot use my screen at 20 inches WITH glasses. Must be the clarity or font size. Some GIF images irritate my eyes so I scroll them out of the screen to read the post. I don't get eye strain headaches, however, if I use backlighting so as the screen is not the brightest thing in the room.

Most of the time I don't need glasses, but my "Vari-Focal" spectacles are handy for protecting my eyes, and makes all round vision when driving, slightly clearer....
My long range vision is fine, but as I get older my close-up vision (reading, etc) is getting difficult.
During my recent eye test I told the Optician that I was having problems with with my close-up vision from 9 Inches, (book reading), to 2 Feet distance...(the Computer Monitor Screen), so they modified a pair of Vari-Focal Lenses to gradually magnify an area in the centre and bottom of the lenses when looking down at objects, and looking at the Computer screen from a sitting position....
...they work perfectly...!
"Vari-Focal" Lenses provide a gradual transition in clarity depending what part of the lens you look through...
Bi-Focals only provide two areas..long range, and short range.

I think Folks who regularly suffer from "Migraine" will suffer from headaches for whatever reason...they are generally stuck with it!...

Paul...a Pint Glass for me...please... ...!

I've had Varifocal lenses in my specs for a long time. They took a bit of getting used to when I first tried them but I'm quite happy with them now. I don't think they're ideal for using with a computer as I have to hold my head up to look at the monitor. I have the same problem with the bottom shelves in supermarkets.

I used to suffer terribly with migraines. Came on all of a sudden when I was in my early 30s. Scared the living daylights out of me. Nothing to do with my eyesight or computers, although staring at a monitor for hours on end can't be good for you. It's more likely caused by diet, too much cheese, chocolate, coffee - that sort of thing. Fortunately I grew out of it just as the 'experts' said I would. I occasionally get the zigzag visual effects but haven't had one of those blinding headaches for years.

One of my lovely Daughters-in-Law suffers from Migraine, but knowing her as I do, I think most of it is caused by stress and worry, often in her Managerial job, etc...

Paul.... ...!

Doug...does you regular; "lying down in a darkened room" help?... .... ...!

I was forgetting stress which I suspect can be a big factor. I used to get migraines mainly at weekends which I put down to a temporary relief from the stress of work. This had the effect of ruining my weekend. I'm sure there must be a medical term for it.

Sometimes it was the only option. Fortunately I no longer suffer from it.

Wearing my glasses seem to help, probably a combination of tiredness as well I guess.
Thanks all.

I never needed glasses, but I occasionally had migraines when working hard at the computer for too long... I know for a fact that CRT monitors give me headaches if set to 60hz... I can see the flicker and it bothers me to no end... setting it up to 75-80hz solves that though...

Also, I have always left the gamma/brightness settings low enough so that the screen isn't, as Steve M said it, the brightest thing in the room. Too bright a screen is a bother to me, and I try to set it to a brightness akin to that of a sheet of paper under room lighting (not as easy at it seems). Also, I never use the pc without a light on.

If it's recently... do you get a new chair? I used to get headaches until I realized they started in the back of my head and I related it to the chair I was using... caused me to sit incorrectly because I had the chair too high.

75Hz should be just fine. 60Hz should be ok too. Do you have florescent lighting? I remember reading about a study where the lighting caused visual problems.
