    Refractify – Optical software against myopia▲174

    Last summer there was an Ask HN[1] about a Nature article that said bluring the blue and green color channels on screen may be good against early myopia development. The OP wanted such software and there was none available. So I quit my job and implemented this software, did a short video with a 3D artist about it. Turns out marketing is expensive, so I made an open source browser extension version too. How it works?

I tested my website with a MacBook camera. Any comments, questions, or suggestions are greatly appreciated! blog: https://blog.andykhau.com/blog/eyesite check it out: https://eyesite.andykhau.com/ github:…
