For lazy eye,glasses along with patching will help.
Patch right eye atleast 4hrs /day along with 1 hour of near work with left eye
Chances of visual recovery are there till 17yrs of age. But speed of recovery is slow as age advances.
Lasik will help you to get rid of glasses but will not treat lazy eye
Having said this,-2.5D can't induce lazy eye.
Kindly send me your glasses prescription along with reports of your doctor so that I may guide you better
