Review on SIGVAN Blocking Eyestrain Lightweight Computer Vision Care and Reading Glasses by Robert Hickey

The glasses came quickly and were exactly what I wanted. good size Fits good. Good quality. The blue light block works. I bought them on a prescription switch so my eyes had to adjust for the first few days, but after a week I find my eyes feel a lot better and are less strained and tired after a full day at the computer. I'm glad I bought them. And there are enough of them to leave in every room. Also included was a cloth carrying case and cleaning cloth.
