Hello
A. I assume your friend must be of your age,so glasses power does not increase at this age.It usually becomes stable at age of 18-21 yrs of age
B. Is 0.2 his glasses prescription? I need little more information about this... Kindly share his glasses prescription and case file so that I may guide you better regarding eye sight and power of glasses
Regards
