3 PACK, Clip on Flip up Polarized Lens For Prescription Glasses, UV Protection Sunglasses Over RX Eyeglasses

I really got these for driving. They are indeed polarized and do a great job knocking down the sun / glare. So far I have only worn the blue ones around the house and around town and driving into the bright sun for a week or so. The clip-on mechanism holds on to the glasses well, and the flip-up action is nice - the lens holds up and basically out of sight no problem. I apparently got used to it because my (teenage) daughter said, "Dad, are you gonna take those things off already?" Score one for Dad.The metal clip-on framework arrived slightly offset from the axis of the lenses. So the first time I clipped them on they were skewed a little, but a few tweaks with some needle nose pliers and voila- perfect. One star deducted here.Finally - my Rx glasses are significantly smaller than these clip on lenses and so the bottom of the clip on lens would touch my nose (annoying) in the down position. I got some sharp scissors and was able to easily trace and trim the lenses to match my Rx glasses. No stars deducted here, in fact - I should add one star back because the plastic material allowed me to easily trim it to custom size without cracking or shattering. Very nice.

The plastics very light and thin, but they were not packed very well. So much so that they were somewhat dirty. They came with a lens cloth that I used to wipe the lens. So I tried them on and I think that I got a case of pink eye or the flu ! Wow, make sure that you that you wash them first before trying them on!

There’s probably glasses and faces out there that these will work for but my glasses and my face aren’t among them. The problem is the clip by which they attach to my specs. The arms of the clip simply protrude too far into the space between my glasses and the bridge of my nose. That means I can’t put my glasses all the way onto my face. The quality of materials and construction is reasonable enough for the price but I think most people will have the same problem I did.

Great value for the price. Product flips up, out of the way, when you want to see without the Lens in place. Recommend buying, because I've had good consistent results and I clean them with a mild soap. Haven't had trouble with scratching, but I take good care of them. Recommend buying them.

I especially like the yellow lens for driving at night. Compliment well with my prescription glasses. The black lens' clip is a Lil crooked and loose but it's OK. Would give it a 5 if not for that

Since I wear glasses, I normally never use sun glasses. When driving long distances in sun shine, eyes become tired. Tried these since they were clip on and eyes were not tired due to eye strain. I haven't tried the the yellow and blue ones yet, but happy with the dark one.

The blue and black were way too dark to use. The only one usable was the yellow, and I'm not so sure if it actually helped. The two darker ones made me feel blind, not enough light. YIPES!

These work very very well. However they were much bigger than my glasses. The bridge was just right, though. So I went to work to make them fit. First, I covered each clip-on lens front and back with masking tape. Then I attached them to my glasses and from the “inside”, and I used a sharpie to trace the outline of my glasses. I took them OFF my glasses and I used an exacto knife blade to trim away excess masking tape outside the original sharpie line only on the inside of the lens.Plug in the dremel with a sanding drum and grind away the excess plastic up to the sharpie line. This part got quite messy, of course.Finally I changed the dremel from the sanding drum to a smoothing tip and cleaned up my wiggly lines. I removed the masking tape and washed as usual. Made a perfect fit, with about 15 minutes of work for each set of clip-ons!
