I wear progressives. As a carpenter I wanted safety glasses for work. I got a wrap around plastic safety glass with a optical insert (metal frame mounts on four small posts and held in place with a rubber nose piece). I have a dark pair and clear pair. The great thing is when the safety lenses get scratched up they are only 12 bucks to replace. The important part (prescription) is protected behind them. My wife says I look like "Bubbles ''. O well I can see great and my eyes are protected.Mike.
