I have a very high prescription (-13) and want some new vairfocals.
I want the lenses as thin as possible, and was looking at 1.9 glass lenses, but am being told they will be incredibly heavy.
I'm a bit disappointed at this, as I've read that glass lenses also give sharper vision.
Please can anyone with experience of this type of lens advise me of their experience, especially whether they are noticeably heavier to wear?
