They work great, fit great and are well made. Not sure what other people are talking about (cheaply made??). I've been wearing BlueBlockers for years but can't find them anymore so I was happy to find something similar. These work just as well for 1/3 the price. They reduce glare and everything is very clear, not dark like most sunglasses. I have very light sensitive eyes & cataracts, these are the only kind of glasses that work for me.
