Review on Sportex AR4145 Gray Reading Glasses for Men – 30.8mm US Size by Lori Allen

The optics of these glasses are perfect, but the fit is very loose. The arms are very soft and flexible, which can make them comfortable, but they just don't hold tight. Even if you try to flex the frame a bit to get your arms closer to your head, the flex in it keeps them loose. The levers are rubber and do not hold the bend themselves. If you're still sitting and reading, that's fine. For example, if you look down at the project you are working on, they fall down. For reference, my hat size is 7-1/2, which is larger than average head size. upset.
