Finally there is a blue blocker in a reader. When computer glasses are tinted with melanin it blocks the blue rays that are emitted from electronic devices. This has helped so many people that need to spend many hours in front of a computer or tablet screen. We now have this flex frame style in a blue blocker computer reader. The powers available are 1.0, 1.50, 2.0 and 2.50. The frame is totally flexible and comes in either brown or black. Frame Measurements: 5 1/4" x 1 1/4" (temple to temple x height of lens)
