CAPTCHAs Stop The Blind

I’ve been seeing sites that use CAPTCHAs that are a series of letters or numbers in an image to log into a site or do other things online. Being visually impaired these make it harder for me to do what I’m trying to do. There have been a few that even enlarging the image didn’t help me be able to read it.

Some of them have such poor contrast or are so distorted there’s no way I could read it. At that point I decide the site isn’t worth my time anymore. I know there are some sites that use ones with sound too but in my experiences they seem to be few and far between.
