Good Look with Progressive Polarized Lenses
4 months ago
Zenni has always provided excellent products at a lower price. I've been buying glasses from them for years. Best low priced perscription readers available. I've never had an issue with thier build or lens's. This purchase was for polarized progressive sunglasses for driving. The progressives with the wider view are fantastic. So much easier to get used to. I may have misordered. since the bows are a bit wide for my head when not in use. When I put them up on top of my head when not in use they slip down easily. However, they are a secure fit when in use. The frames seem a bit flimsy. Maybe I'm just used to metal frames or thicker plastic frames. Overall, very nice glasses when used as progressive polarized sunglasses for driving.

The frames fit great and look good. They are super light weight and comfortable. You also nailed the prescription perfectly. I can see again!
