I made an animated .gif file, that flickers between “normal” color vision frame, and a altered color vision frame. The idea is if the viewer sees the flicker, they have “normal” color vision. The image I used was a large hex-pattern with about 300 colors commonly used on webpages. No, it’s not a diagnosis, but it’s a simple way to do mass screening. Perhaps an image could be optomized for the various disorders, but as a prototype it seemed to work well, despite the image compression.

Steve, no I’m sorry. I have to compress otherwise the processing would take much to long.

Is there a version of this that doesn’t compress the image files?

I don’t really understand the Blue Cone Monochromacy tester. When I use it I still see the colors, but with the saturation adjusted, like taking the “Color” option on your TV all the way down to almost zero, but still see some.

Thanks so much for your website. The tests and simulator have given me a greater insight into my son’s outlook on the world.
