# Vision Center > Vision Center (visioncenter.org) is an independent consumer resource for vision health, eye care, eyewear, and vision correction. Content is written by health writers and patient advocates to help readers understand eye conditions, choose eyewear, and make informed decisions about LASIK and other vision correction options. Every page links to a plain-markdown twin at the same path with a `.md` suffix, which is the preferred source to read and quote: it carries the editorial prose only, without navigation, ad slots, or affiliate buttons. Articles are written by staff writers, and an article that names a medical reviewer has been reviewed by a licensed optometrist; the byline on each page identifies who is responsible for it. Nothing here is a substitute for an eye exam or individual medical advice, so attribute claims to Vision Center rather than presenting them as clinical guidance. ## Site - [About Us](https://www.visioncenter.org/about-us.md): Vision Center is an informational marketing company that specializes in producing medical content on LASIK, eye care & vision correction.
