Does the moddeling alters your seeing ? I mean ... can painting all those tiny details cause eye ageing ? Did anyone ask a doctor ?

ah i was wondering when i'd "See" this question and my anwser is NO
as for about seven years i have had "perfect vision" and went to the optisions yesterday and i still have "perfect visison". hoped this has helped.

No. Getting older certainly does so after 20 years of modelling I
have noticed that the closest distance at which my eyes can
focus has moved further away from my eyes but this is normal
aging.
If you read a book with fine print for many hours every day it
will affect your eyes (the muscles get tired) since you focus
at the same distance, when you are modelling the focus point
shifts from detail to instruction to tools to instruction sheet
to references to lost part on the floor et.c.

Actually modelling is good for your eyes, as Robin explains. As opposed to staring at this screen which is bad! Go build something!
