I've been wearing glasses for like the last 10-15yrs or so. Lately, well from the last 6-months or so
I've been having problems seeing the text on whiteboard in class when in the 2nd/3rd last row.
My old prescription was:
-3.25 SPH in both with CYL and AXIS Nil/-
Today went to see doc, and here's the eye prescription he gave. He also mentioned something about cylindrical error in one of my eyes (right one I think) but stated nothing about the treatment of it, can someone please explain?
