LIYANHU 4 Pack Clip-on Sunglasses for Prescription Glasses, Polarized Flip-up Sunglasses with 4 Bags, Suitable for Men and Women

Perhaps it was a mistake to try these out with my young granddaughters in attendance, but they were described as "cool" by one of them ( to the great amusement of the rest of the family). They other one was hugely amused by the flip action. It's a heck of a lot quicker than photochromics though and probably just as effective.

These fit my glasses perfectly and have improved my sight driving in sunshine. Not tried night vision yet. Love being able to lift up - far better than reactolight as have instant change from dark to light which I prefer.

Bought these to have a dark set in each car , each pair comes with a bag . Easy on and off

Range of shades

Perfect,the best I have had

Great for reading outside in strong sunshine

weak and flimsy

Needed some in a hurry, so gave these a go. To my surprise for the price, they are a good fit, easy on/off and can fold up while wearing them. So nice my wife took a pair off of me.
