Phillips Shade 3 Flip Ups For Over Didymium Sunglasses

These are the 3.0 shades that clip on at the center very easily. I use the 3.0 lenses over my didymium glasses myself, but for long hours and tired and sore eye's, I recommend the 5.0 Shades. (Very Lightweight) I Love Them!! Clip-on Flip-up Shade 3.0. If you are using didymiums instead of the proper borosilicate glass eye protection and you are not ready to purchase a proper pair, you can use these clip-ons temporarily. Should be replaced periodically.
