If you’re really serious I would first recommend you familiarize yourself with the needs of blind users generally. Like try using the internet with your eyes closed and a screen reader to understand how a blind person would interact with a website. Maybe you can ask around or Google some tips for getting started with that.

I had a former coworker who was a UX designer and he taught himself to use a screen reader for this reason since he was required to ensure anything he designed was accessible.
