Bests & Worsts Reviews from Amazon

[PHOTO/VIDEO] on TOP = "Foster Grant Wes" / on BOTTOM = "Gaoye Gy1701" I go through 2-3 pair of Foster Grant multifocus reading glasses every year, because they break or get scratched fairly easily. That gets pricey after a while -- I've bought 8 pair so far, and just ordered more -- so for years, I've been waiting for cheap knockoffs of the Foster Grants to appear, and got excited when I saw these on Amazon. Unfortunately these have awful optics. I have to agree with the other 1-star reviews of this product. 1) The center of each Gaoye lens is distorted like a fisheye. At my desk I look through the center of the lens at a large computer monitor, but the magnification puckers around the center, so the screen is in focus within a tiny area in the middle of the lens. The attached photo and video illustrate the issue (Gaoye on bottom). Imagine working at your desk, looking through that puckered spot in the middle, and straining your eyes due to all the distortion around it. It might appear to be a big enough area to look through, but in practice only small area of the computer screen is in focus -- maybe 5 words of text at a time. You have to move your head in tiny precise movements to keep in focus the words you want to read, while almost everything else in view is blurry. There's no way to get accustomed to that. 2) The middle and bottom of the lenses differ by the wrong amount. The bottom of the lens should have the full-rated magnification, and the middle should be about 3/4 of the full strength, but that's not what I experienced. -- With the Foster Grants, when I look at my laptop screen through the bottom of the lenses, and then look up through the middle of the lenses at my external monitor (which is about 8 inches behind my laptop screen), both are in focus. That's the whole point of having multi-focal glasses. -- With the Gaoyes, when my laptop screen is in focus through the bottom of the lenses, then everything else above it is blurry, including the external monitor. Then if I adjust my head so the external monitor is in focus through the center spot of the lens, then laptop screen is blurry. In order for me to use these Gaoye glasses, I'd need to rearrange my desk, but even then the optics are so distorted I don't think it'd help. 3) The distance portion at the top of the lens isn't great either. The optical distortion reaches nearly to the top center of the lenses (see the photo+video), so there's only a thin slice above it which is good for viewing distant scenes. I hope in some future iteration, they fix the optical problems. But seeing how Gaoye/Livho seem to be paying reviewers to leave 5-star reviews, they may more interested in scamming customers than improving the product. Positive aspects of Gaoye glasses: A. Half the price of Foster Grant or Sightline B. Very lightweight C. Blue light blocking seems effective D. Stylish, in the sense that nowadays it's more fashionable to have large lenses (although it's not my taste) If you want plain lenses with no magnification, then I'm guessing they'd be fine. But then you might as well buy those "Livho blue light blocking glasses" that all these 5-star reviewers also reviewed. You might go look at the "AOO Keyboard Cleaner" too, seeing how it's getting such good reviews from these same reviewers. BTW, I also bought a pair of the FEISEDY multifocal glasses and almost everything about them was identical to the GAOYE ones. You can look at the product description of the FEISEDY glasses to see a little more information about the optical design. In the end, I returned both the Gaoye and Feisedy glasses, and bought more Foster Grants. P.S. Sorry the video resolution was lowered so much after upload that it's very difficult to see the fisheye effect.
