A member asked:

I can blur my vision on command. is this normal?

A doctor has provided 1 answer

Accomodation: There are neurological inputs to the eye which can cause the lens to alter it focus. You probably are calling into play 'accomodation' which can do this. This is a normal reflex and like many controllable reflexes, can be exercised more with practice although i don't think it has a practical value.
