Your survey refers to people with vision loss in the third person. If you are asking someone with vision loss you fill it in, it would be slightly more polite to ask directly. (Example, Fourth question says "What kind of work arounds do *they* currently use to address these pain points?", rather than "What do *you* do?").

You may also want your survey to find out at the start if someone is totally blind versus low vision. Many people who are low vision use screen magnifiers, while someone who is totally usually uses screen readers. Web inaccessibility affects them in different ways, and it would be useful to know what their situation is. Also, someone who is low vision can use both a screen magnifier AND a screen reader, but someone who is totally blind usually can't use the magnifier.
