Macular degeneration is associated with long-term exposure to light radiation from tablets, cell phones and computer screens. I already have to wear readers to work on my computer, so having readers that block blue light kills two birds with one stone. Comfortable and stylish, these qualities are very good. Eventually I always manage to scratch the coating or one of the levers breaks at the hinge. I usually change them every 6 months or so. The manufacturer or packer has become a little cheaper over time. Would have preferred if they went back to the ones originally broadcast. Good thing I still have some left to use.
