Joopin 1 Pair Clip-On Driving Glasses Rimless Flip Up Style Anti-Glare Night Vision Sunglasses for Driving

I lost my last clip-ons and with summer coming up, decided to try these. This brand provides very good blockage of sun and glare but still maintains crisp vision. These not only clip-on to your glasses but have a hinge that allows you to flip them up which is handy if you're going in and out of the sun. I live in a heavily wooded area and so part of the road will be sunny but some will be heavily shaded---too much for sunglasses %26 transitional lens can't change quickly enough. The clip-on and flip-up sunglasses solve this problem.
