Ask HN: Do computer-based glasses exist that replace progressive/bifocal lenses?
These computer-based glasses could just vary what you see in each eye rather than requiring you to look up/down to see far/close objects.
- dave4420 2y agoIt feels like “just” is doing a lot of work. Do you mean by dynamically changing the strength of the lens, or something more like Apple’s Vision Pro?
- amichail 2y agoI mean something like the pass-through feature in the Apple Vision Pro but designed for people who need progressive or bifocal lenses. The device would be compact and intended primarily as a replacement for glasses with progressive or bifocal lenses.
- aurizon 2y agoI have seen some people selling a self focussing set of eye glasses that had a sonar range finder a few years ago. Not sure if it ever took off? It seems doable with current self focussing camera tech and 2 small cams above the eye to get range and a hydraulically adjusted lens for each eye that it is doable. I am sure work is being done on this? Google shows a few. Ignore the amazon ones = Chinese junk https://www.google.com/search?q=auto+focus+eye+glasses&rlz=1C1CHZN_enCA1101CA1101&oq=auto+focus+eye+glasses&gs_lcrp=EgZjaHJvbWUyBggAEEUYOdIBCjEyNzc0ajBqMTWoAgiwAgE&sourceid=chrome&ie=UTF-8 https://www.google.com/search?q=auto+focus+eye+glasses&rlz=1...
