I have very bad eyes - nearsighted. So my lenses cost a shit load b/c they have to make them using the thinner material to avoid Coke Bottle Look. So I know about bad eyes. I recently visited my ophthalmologist b/c I was complaining of eye strain from using the computer too much, and he suggested the blue light filter. https://www.zeiss.com/vision-care/en_us/better-vision/understanding-vision/eye-and-vision/blue-light-the-good-and-the-bad.html It's like night and day. I went to Costco and ordered new frames with the blue light filter and progressives (indoor/outdoor use). so reasonable compared to what I'm used to paying at an optical store. Go, Costco! But my main point was about the blue light filter. I don't have the headaches I once did! |
