CHB Ultra lightweight polarized pilot sunglasses for men 100% uv protection

These are a nice shape, the lenses being more 'rectangular' than most other 'aviator' style glasses but the arms may be a bit short for me. These are 5.39 inches (137 mm), they reach my ears but do not curve down behind them very much. It's probably the angle of curve more than the length but I don't want to attempt bending them down so I'm hoping i will get used to the (looser) feel as otherwise they are great.
