If you’re looking for clinical evidence, save your money. But if you’ve been taking neem and noticed that your vision has improved, please let us know.
I made a comment last month about my eyesight improving to the point where I no longer need glasses (after 40 years of wearing them) and posted a review from another customer who’d seen the same thing. We got so many questions about it that I promised to do a deep dive into the research and see what I could find.

After spending two weeks with “Dr. Google,” I couldn’t find much research, and absolutely nothing by the usual standards of the peer-reviewed documentation that we try to report on. The lone peer-reviewed report on improved vision came from the Journal of Chemical and Pharmaceutical Research but it didn’t list the citations you would expect so we couldn’t go back to the original research. It did recommend neem leaf juice applied topically for night blindness and conjunctivitis with no supporting documentation.
I’d expected to see something that tied back to neem’s antioxidant properties because antioxidants have been linked to reducing the risk of serious eye diseases like macular degeneration and cataracts. That makes the most sense to me, but I couldn’t find any credible links, so we’re back to assuming not proving they’d be effective. (On top of that, some researchers are questioning the value of all antioxidants in terms of improving vision or preventing illness.)
Some reports mention neem as an antibacterial and antiviral, but that wouldn’t explain why some people are able to give up glasses after decades of wearing them. And there were a number of generic reports (mostly from international websites selling neem) saying that “research has shown that neem can improve night vision, relieve visual fatigue and protect the eyes from glaucoma, cataracts and macular degeneration.”
Again, no documentation, so we’re pretty much back to where we started. I probably wouldn’t have published this article if we hadn’t gotten so many comments on that first mention so we’re tossing it back out there!
Anybody else who has given up their glasses after decades of wearing them?
Ironically, the only article on neem and vision at the National Institutes of Health library reports on an Indian woman who drank five ounces of neem oil in a suicide attempt and temporarily lost her eyesight so there is some connection between the active ingredients in neem and vision.
