These are amazing, and not just for the up front use as sunglasses. If you are stuck in a wheelchair and have to navigate the real world in the urban jungle during the summer these are life savers. The neck strap keeps them from falling / getting lost , as well as being able to hang them up ( so as to not scratch the lenses ) instead of laying them on a table. Desert summers are brutal, but these will protect your eyes and help you navigate through 110 degree days like no other. They do not 'feel' like regular sunglasses but that is because you are getting protection , fit and function. You may not win any fashion contests, but you will cross the finish line in first place and with your eyes intact.

Glasses did come with the strap other than that they look good

If you have a thin face and/or a deviated septum like I do, you probably want to pass on these. While solidly made, the fit is not great. The frames are very ridgid and the nose piece is part of the hard frame. They do not seal under my eyes and leave about an ⅛in gap where dust can get in. If you try to tighten the strap to flex the frames slightly you just end up digging the hard plastic into your nose which causes a lot of discomfort. If you have a wider face with some meat on your bones, they would likely work very well, but for us thin boney faced folks probably better to look at a different brand.

I got these not for working, but to use instead of ski goggles. The optics are not bad all things considered, but the gasket fitment is poor and uncomfortable, causing sharp pain in my nose bridge.Also they lag fog treatment, so they instantly fog in cold weather.

I ordered these because they were said to be anti-fog. Well, they are. But, they build up moisture inside like rain on a windshield with the wipers off. But, hey, they don't fog.The interchangeable arms and strap are super. The foam-ish piece around the eyes isn't a perfect seal, but it does its job well, and it pops out and back in easily.Aside from the moisture issue, these are some great glasses.
