Hi all, sorry to post this litte off topi not photography related.
I'm goin' to buy a graduated mask, i'm a little shotfocussed and outside the water i have -1.75 and -1.25 (very little astigmatism that i can think about not correcting) i've been told that i have to decrease the correction of 25% while on my beliving air whater interface is a positive lense so i was thinking about increasing the correction.
Anybody that can clarify this point ?
P.S.
I can't use contact lenses.
