If you need stronger in one way, and weaker in another way....isn't that meaning your prescription is even further apart then before? Maybe it is the gap is too wide in strengths? I am no expert, lord knows, I can hardly keep 'far sighted' and 'near sighted' straight, and have worn lenses for WAY longer than I care to admit...LOL.

I am glad you posted this, though, as I want to get a new rx and buy these glasses!!
