Photochromic Clip On Sunglasses,Polarized UV400 Anti Glare Flip up | 60 * 42mm

Brilliant product. Great fit, good polarised filter, and like the hinge option. Now I don't need to choose between being blinded in the sun with my prescription glasses, and being blind in my sunglasses...

My Honda Jazz has something like a 45 degree angled windscreen.A huge slab of grey plastic dashboard, that honda should have painted a non reflective matt black , that in bright sunlight then reflects up off the windscreen, making it a nightmare to see out of the windscreen in bright sunlight.The polarisation on these clip-ons massively cut down the reflections of the huge grey slab of dashboard. So for my issue these work really well. Driving in bright sunlight is now a lot easier. It's almost as if the windscreen isn't there anymore !I did test the polarisation with another polaroid filter. These clips are definitely polarised. See a search of youtube videos on how polarisation can cut down on reflections, and how it's possible to test polarising filters.I don't know how well the photo chromatic bit works and the tint isn't that strong. But then I didn't want a strong tint, I wanted polarisation, with minimal light loss, and to cut down on certain angles of reflected light. So for me, and my situation and use-case, these are pretty close to perfect.

Pros: Lightweight, can be worn indoors, worth the price. Flip up mechanism is helpful, especially when one is driving and need to check something quickly on the phone without taking off the glasses.Cons: Not sure what the nigh vision quality is. Expected it to be darker in the sun (but it does its job)

The flip-up mechanism is too large. It obstructs vision too much whilst driving. They also don't darken/lighten with varying sunlight, as claimed. Fit and quality seem ok though.

Lightweight, comfortable to wear. On first using them, the centre bridge clip seemed to be in my vision. But very shortly after, I didn't even notice it. They cover my prescription specs perfectly. Just dark enough to reduce sun glare whilst allowing good vision.

Brilliant if you have to wear prescription glasses. Very lightweight and very restful on the eyes. I noticed one comment about the bit between the lenses is large and felt it did nothing for the look. So what I can't see that bit

these are fantastic, reflects light on roads , dashboard, water.not very dark lenses but do react to light , I bought some for my parents too and they love them aswell

Used to clip onto a pair of ordinary glasses and does the job well blocking out the sun and also easy to put on and take off. Only downside was the size is a little confusing when ordering as I’m not sure many people know what size their glasses are.
