I love these clip on sun glasses!  They work great in terms of filtering the sunlight and making your eyes feel more comfortable on those very sunny days.  With winter and the snow coming soon I will be using these clip-ons even more than during the summer months.  When the winter sun glares on the brilliant white snow that covers the ground and roads, these glasses give me the comfort I need.

I searched the local stores for these "old fashioned clip ons" because they clip on to the frames on top of your glasses near the nose piece.  They do not mar or scratch the glass on your glasses whereas the newer models of what they call clip-ons actually clip onto the optical glass and have in the past actually scratched my glasses.

I highly recommend this product.
