Does taking photos affect your eyesight???
I would check the dioptre setting by aiming the camera at a blank wall or sky and adjusting the viewfinder until the etched lines on the screen are sharpest. Then you are focusing your eye on the screen with your eye at comfortable rest.
You might be straining with a basically misadjusted viewfinder and your eye is taking a while to readjust afterwards.
Having said that, if you have a problem with your eye the first person to see is your optician or doctor or both just to check it out.

Luckily, the K20D diopter adjustments affect me a lot less than did the Sony A200 which I sold recently.
I wear milk-bottle bottoms for specs, but after using the Sony, my right eye became as sharp as a pin for about 15 minutes, whilst my left eye got a lot worse!!!

Having switched to a DSLR, i have only taken one shot using live view mode, the rest have all been composed through the viewfinder. I've also used the information in the viewfinder when adjusting settings etc.
The problem i have, is that for a while after i take a few shots, i find it harder to focus my right eye on distant objects. It returns to normal after a while but i'm worried that there might be some lasting effect on my eyesight. Anyone else experiencing this?
