About NatureSphere

Updated 2026-10-08 · NatureSphere Editorial Team

NatureSphere is an independent research site about eye health and vision support supplements. Our goal is simple: help readers see what a product's official page actually says, what it leaves out, and how its ingredients line up with public research, before they spend money.

Who runs this site?

NatureSphere is run by a small independent editorial team. We are not doctors, optometrists or pharmacists, and we do not present ourselves as such. We are not owned by, or paid to write by, any supplement manufacturer.

How do we research products?

For each product we:

1. Read the official sales page and, when available, its text version, FAQ and order page.
2. Record only facts stated in text: ingredients, directions, prices, shipping and guarantee terms. Anything shown only in an image, or not shown at all, is reported as not disclosed.
3. Note contradictions on the official page instead of choosing the more flattering version.
4. Compare ingredients with information from the National Eye Institute, the NIH Office of Dietary Supplements, the NCCIH, MedlinePlus, the FDA and the American Academy of Ophthalmology.

We do not buy or test products, publish ratings or stars, or use customer testimonials.

How do we keep pages up to date?

Supplement offers change often. We recheck official pages periodically, update prices and terms when they change, and show the last update date on each page. If an official page stops working or no longer matches what we described, we revise or remove the content.

What this site is not

NatureSphere does not give medical advice. Nothing here is meant to diagnose, treat, cure or prevent any disease. Please see an eye care professional for any change in your vision, and talk to your doctor or pharmacist before starting a supplement.
