They are so sturdily built. I cannot live without them, so I have a few pairs just in case I forget one in a hotel or somewhere else, but so far, I haven't. I take them with me wherever I go as I love to watch TV with them. I have a great way to avoid those awful, bright, blinding hotel lights. With these glasses, my evening at any hotel is so COSY now. I find that I can sleep so much better since I got them, and I have had them for years already. My husband loves his pair as well. We both use the same size, and they mysteriously fit us both so well, even if our faces are very different in shape and size. I have dropped mine a few times, and they are still working great. My oldest brother used to tear at night while watching TV, and I gave him a pair of these glasses, and it corrected his problem. No more blue light damaging our eyes and our emotional self. I find that I feel so much calmer and happy at night when I wear them. Review: Great for long hours at a computer - I got these specifically for use when working on the computer for long hours. The blue blue coming from the computer monitors was really making my eyes tires. So put these blue blocker glasses on and that eye tiredness just isn't there any more. I can work on my computer for hours at a sitting when I need to with almost no strain thanks to these glasses. ## Features - FIT OVER DESIGN: These glasses fit over top of prescription and reading glasses, allowing you to convert your existing eyewear into blue light blocking glasses. They can also be worn on their own - SUPERIOR BLUE LIGHT BLOCKING: The best selling Spectra479 amber lenses can now turn your prescription and reading glasses into anti blue light glasses for computer and nighttime tv use - BRIGHT & CLEAR LENSES: These are designed to pass as much non-blue light through as possible. There is no dark tint and they are not polarized. You can still make eye contact with loved ones and even forget you are wearing them - TECHNICAL SPECS: Tested to block 99.9+% of light from 280 - 510nm (this includes UV). The wavelengths between 450 - 510nm are the most disruptive wavelength of light at night.
