Yellow Night Vision Polarized Clip-on Flip up Metal Clip Sunglasses Driving

Not useful. Leaves marks on the primary spectacles.

The clip is fiddly. my old ones did a better job as anti-glare and as a night vision

Good

cumple la funcion

I'd like to give this more stars, but it's a bit to clunky for total comfort when flipped up. PRO - the true flip up feature is essential. I need to choice to raise or lower, this works great for that. The tint is good enough to reduce the glare of most HID or pick up truck headlights, and not too dark that it reduces night vision. Fits well beyond the size of my prescription glasses, a bit of overlap is good. CON - when flipped up, they feel a bit clunky and you are fully aware that there is something hanging off your forehead, HOWEVER, they do the job, if you are ok with looking a bit dorky
