I love twenty twenty eyes! I've been a customer for 3 years now, and I have 3 pairs of glasses I've purchased from them. My newest pair has an l.a. Eyeworks "Litebox" model frame. The lenses are digital and they're progressive bifocals. At first, I was hesitant to get bifocals because I heard they'd be hard to get used to. However,during the fitting,Ron showed me how to read with them and how to look through them to see near and far. By the next day, I was used to them. In less than a week, it was as though the bifocals were just regular glasses. Also,with the digital lenses,everything is sharp and clear -- whatever the distance. Ron, the owner of twenty twenty eyes is professional and curteous. He always makes a great pair of glasses. Visit twenty twenty eyes and see for yourself.
