the eye strain you must be getting with the amount of time on the comp. I know my eyes went from better than 20/20 to wearing reading glasses of 150 power (and climbing) within a few years I started to work with computers.
I now have some hand/finger exercise gadgets on the computer desk and use them to relaxe the tightening muscles. I have also noticed I am putting more frequently used hotkeys on the right mouse button - My index finger is getting stronger
Good Luck!
