Pardon me if this question seems ridiculous. I am a layman trying to find out as much information as possible about the mysterious world of progressive lenses. When my eyes were examined in the opticians' shop, I was given a prescription for a 1.6 lense. Would the same prescription be valid for a 1.5 lense? Or would the prescription need to be modified?
Here in Spain, they mentioned the possibility of "thinning" a lense. Is this practive advisable, or is merely for asthetic purposes? Thanks.
