I am a school nurse and I looking for free eye exam for children with a low income families I do have a resource for free eye glasses but they need a prescription first.

Id contact your local health provider, Over here in UK (sorry don't know where your from) all children in full time education in uk are entitled to one free eye exam every 1-2 years depending on their eyesight and one pair of free glasses every 1- 2 years, that's the one good thing about the NHS. Hope this helps. Sorry if not x

Unfortunately here in America health care isn't free. Please take a peak at my sticky note on this subject, if you still have any questions please feel free to ask. https://www.askmehelpdesk.com/vision/free-glasses-free-eye-exam-218963.html
