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? There is a small neural network on the retina that tries to detect if the eye is far-sighted(most people are born far-sighted), and it is producing dopamine to slow or increase…

I wanted Apple Vision Pros, but I don’t have $3,500 in my back pocket. So I made Apple Vision Pros at home. This was just a fun little project I made. Currently, the website doesn't work on screens less than 1200x728 (Sorry mobile users!) It also might struggle on lower end devices. For best results, have a webcam pointing right at you. 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:…

A simple mobile web app inspired by Fuzzy-Search/realtime-bakllava that uses llama.cpp server backend with multimodal mode to describe and narrate what the phone camera sees. I built this thing in a few hours using a single ChatGPT thread to generate most things for me and iterate on this project. Here's the workflow: https://chat.openai.com/share/ea84ec69-5617-45e8-8772-ac2dcf...

The difference in cost between products that are developed as accessibility tools compared to consumer products is huge. One example is camera glasses where the accessibility product costs ~$3000 (Envision Glasses), and the consumer product costs ~$300 (Ray-Ban Meta). In this case the Ray-Ban Meta is getting accessibility features. The functionality is promising according to reviews, but requires the user to say "Hey meta what am I looking at" every time a scene is to be described. The battery life seem underwhelming as well. It would be nice to have an cheap and open source alternative to…

Hey everyone, If you're anything like me, you spend a good chunk of your day (and night) on your computer. I often find that when I'm zoned in, my posture gets worse and worse and my face ends up being really close to the screen. And over a course of a workday, when I finally unplug, my eyes have a hard time focusing on things that are far away. This has become a big enough problem for me that I decided to create an app to help me keep my face far enough from the screen. Now, I could've gone with a simple notification with a timer built into it but, as with all reminder notification, they…
