See What Customers Are Saying
"I love the FL Blend lenses; when I was working, the FL Pro saved me from the eye sensitivity I was experiencing; now that I am retired the Blend works well for me on those days when I need it most. I love them!"
"I tried a new kind of lens, the blue ones, and it is a terrific addition to my eye protection. I look through them and everything relaxes in my vision and brain. My new favorite."
"Their options for those [with] light sensitivity surpass other companies offering far more expensive alternatives. We have gotten great feedback on their newest FL-41 Blend option from our patients. Can't recommend their FL-41 products enough!"
