Show HN: I'm color blind, so I built a way to show people how I see

I'm color blind and for as long as I can remember, the first question people always ask me after finding out is: "what color is this?"

So I thought it could be cool to build a color blind simulator where I can point my phone's camera at anything and show people live what it looks like to me.

Once I built that, I thought it would be interesting to also see how other people with different vision issues see too. So there are also 20 other conditions you can experience, along with a short color blind test if you want to check your own eyes & share a link to how you see.

It all runs in the browser and your camera feed never leaves your device. Thanks for checking it out

This is awesome, thank you. Few observations from my own experience: floaters are smaller, less hair like and more blood vessel like, and they are always on the move. I have three more temporary conditions to suggest that might be interesting: 1.) PVD - Posterior Vitrous Detachment: considered harmless, milions of dark speck floaters all moving due to eye movement inertia, clears out naturally after a week, 2.) Retinal Detachment, considered a medical emergency: dark shadow in random corner slowly becoming bigger and bigger day by day, can be stopped only with a surgery, leads to complete blindness if left untreated, 3.) Gas Bubble, a temporary consequence of a retinal detachment surgery, lasts about a week, starts as fully blurred vision which is gradually being replaced by perfectly focused vision in a horizontal line that falls down like a curtain. In reality the eye is absorbing the gas and replacing it with vitrous liquid slowly, but due to camera obscura optical properties this is perceived as upside down, so the liquid surface line is not rising up from the bottom, but falling down from the top.

Hi, would love to try this out. However, i can't seem to find the link!
