Affiliate Disclosure

Updated 2026-10-08 · NatureSphere Editorial Team

NatureSphere is reader-supported. Some links on this site, including buttons that lead to official product websites, are affiliate links. If you click one and make a purchase, we may earn a commission from the retailer, at no extra cost to you.

Which links are affiliate links?

The buttons that lead to the official websites of OptiPlax, EyeFortin, Visium Plus, TheyaVue and SharpVision are affiliate links. Orders for these products are processed by the retailer BuyGoods. Links to health organizations such as the National Eye Institute or the NIH Office of Dietary Supplements are ordinary links and earn us nothing.

Does this affect what we write?

Commissions do not change how we describe products. We report what each official page states, point out missing information and contradictions, and include cautions and drawbacks for every product. Some products we track have no buttons at all because we could not verify enough information about them.

Your choice

You are never required to buy anything. Please read the official product page, check the refund terms and talk to your doctor before ordering any supplement.

This disclosure is provided in line with the U.S. Federal Trade Commission's guidance on endorsements.
