Why is my computer giving me headaches?

Hi,

So I keep getting terrible headaches from looking at my monitor, even if it's just for a few minutes.

I use a TV screen as my monitor. What's weird is that when I watch TV on it I have absolutely no problems, but when I use it as a computer I get the headaches.

This suggests that there is nothing wrong with the screen, but what could be causing the headaches?

I have never had a problem looking at any other screens/ monitors before.

Any suggestions would be greatly appreciated, thanks.

You've answered your own question. TV Screens are not designed to display text crisply. You are straining your eyes trying to focus

Ensure the computer graphics are set to 60Hz refresh. If lower it might be the cause.

When you watch TV you tend to sit further from the screen than when you are using a computer.

Because you are sitting so close you need proper glasses for working on computers hence the headaches.

They say normal reading glasses will do but that is not the case. You have to measure how far your eyes are from the screen when buying glasses. My eyes are approximately 22inches from the screen so the optician would take that into account when making glasses for computer work.

if you do not normally wear glasses you need them now.

Govan1x may have hit your nail right on the head. I wear glasses routinely and use varifocals for most things, however, for the computer I have single vision lenses with the focus distance set for the job. Makes things much easier and avoids eye-strain.

Also consider whether there is any noticeable flicker from your tv screen, it will be much more apparent when you are closer to the screen.

Thank you all for expanding on my first answer

I use an old pair of reading glasses for computer work as my eyesight shortens, for the above reasons.

Make sure you act on Alan's advice and ensure the monitor refresh rate is 60Hz. If it's lower then the screen will flicker and can easily cause the problems you describe.

Before I retired I worked in the Netherlands and had a 4 screen workstation. My company paid for a special pair of "triple" vary focal size, the top for distance, the middle to focus on the monitors about 45 or so cm away, and the lower zone for reading. Don't bother at home but I wonder if special vatyfocals are used in U.K.?
