I have used blue light blockers from various suppliers for 2 years now. When I got my VivaRays 4-1 prescription glasses, I felt like I got the Farrari of blue blockers. They are perfect. The prescription is spot on, and the magnetic "clip-ons" are convenient and easier to use than traditional clip-ons. The customer service is above and beyond. They answered every emails quickly and put a rush/priority on my order as my old glasses had been smashed and were superglued in 2 places. Thank you VivaRays!!! Thanks for everything!
