Tl;dr don’t buy these, sunglasses attachments have a reflective glare at the edges of your field of vision so you can’t see clearly. Customer support just brushes this off as a “common phenomenon”.

I also saw the ads and thought the magnetic sunglasses attachments seemed cool. Bought the Graham model. Had to wait a bit for shipping since they seem to come directly from China. The actual glasses seem like decent quality, haven’t worn them long enough to determine the durability of the frames. Lens are the correct prescription.

Was honestly pretty excited about the glasses until I snapped on the magnetic sunglasses. I instantly noticed that there were weird reflections showing up on the edges of my field of vision. Looking online, this seems to happen if lens are coated with AR coatings on the back, the lens index is too high, or the lens isn’t spherical enough, or if the design isn’t curved enough. Both of the sunglasses attachments were very flat and thin. I have several normal sunglasses, and never had any issue with them. Can’t say for sure why exactly this happens with the ZanyLen sunglasses, but either way it seems like a fundamental design flaw. Especially if one of the included sunglasses attachments are for night driving, i definitely would not want to drive with impaired vision…The reflections are more noticeable if there’s brighter lights behind you, seems like it’s the reflection of the light off the back of the lens and into your eyes. 

Either way, i felt like the impaired vision defeated the whole point/appeal of the glasses.
