Great quality frames. I would actually say on par or better than my prescription Maui Jim's.The are almost exact replicas. The lens i found out was nowhere close to Maui's. Maybe because i need a slight corrective lens to see my sharpest but have used other non prescription Costas and Sun Clouds that are pretty sharp. I would say if you have good eyes and want a pair of Maui's for a fraction of the cost and need them to be readers this is probably a good choice. Remember they are only 30 bucks the same price a cheap pair from a retail store.
