Polycarbonate Clip-on Flip-up Bright Orange Enhancing Driving Glasses -58mm Wide X 47mm High (131mm Wide)

Although I don't think they are "all that thick", my lenses are too thick to put these on easily. It's hard to open up the clips far enough. I did use them a few times and they seemed to block the blue light, but I didn't use them enough to really know how it will effect my sleep. Seemed fairly sturdy. I'm going to try some fit over type.

Useful for people who dislike bright lights and find that nighttime TV use interferes with sleep. Sturdy mechanism clips onto glasses. Easy to put on and remove. Very satisfied.

serves a purpose but wouln't purchase again.

Gos on easily and stays in place. I bought the clip on for shooting trap over my bifocals love em.

Good and durable but I would prefer to have known that green traffic lights are hard to see with them.

Great for use during a sunny day or at night to block glare. I would recommend these for all who perfer clip on's

I ordered three colors of these clip-on sunglasses, orange, yellow, and brown. Haven't had a chance to use them yet, but appear to be well made. I am happy with my purchase, and will buy more in the future.

I purchased these for trapshooting to brighten the target and eliminated most of the background color. They work very well for that purpose.
