If you are a front-end developer, and don’t understand why building accessible interfaces is important, I highly encourage you to read Laura Kalbag’s Accessibility For Everyone: https://laurakalbag.com/book/
There’s this misconception that accessibility means making sites work for blind people. Accessibility is so much more than that! (And even if it wasn’t, 🖕 if you think those with vision problems shouldn’t have access to the web).
