I'm browsing Flikr images, and small pics are making my eyes strain.

So I have increased the size, and moved my eyes further away, but the image is now working out as the same size as when I had my head nearer the screen (Obviously)  But It got me thinking, the pic is still the same size going through my eyes, yet no eye strain...
So what about when outside, if you englarge a tree leaf, so it is the same size as when you had your eyeball right in the leaf giving you strain...
Am I making send

Your eyes will have to focus on the screen in either case, so you may have a problem with properly focusing at a closer distance.

This does make a difference. Eye strain doesn't usually have anything to do with the apparent size of an object.

It's quite interesting though isn't it  
I mean when I've been on the computer a few hours, I go outside and see car Number Registrations a bit out of focus so takes a while to get my eyes back to long distance

Yeah... it's probably the muscles being a bit stiff which push the lenses back into a different focus which you hadn't used for a while.

Or you should get your eyes examined. That is always a good start if that change in ergonomics that you've made is not cutting it.
