An Evaluation of Popular Online Eye Health Products on Amazon Marketplace.

BACKGROUND AND OBJECTIVE

To investigate popular eye health supplements available on Amazon Marketplace to increase awareness about their efficacy, safety, and the validity of their purported benefits.

MATERIALS AND METHODS

An observational quantitative and qualitative analysis of the top 100 eye health products was performed in March 2019. To determine the popular online eye health products on Amazon Marketplace, eight keywords were used for the search: "Eye Health," "Eye Health Supplements," "Eye Health Vitamins," "Retina Vitamins," "Macular Degeneration," "Macular Degeneration Vitamins," "Macular Health," and "Vision Health." The active ingredients, cost, and customer rating were all recorded.

RESULTS

No statistically significant association was found between product type and price of the product, number of supplements, average rating, number of customer reviews, or number of verified customer reviews. The average daily cost of the eye health supplements was $0.72 ± $0.55 (range, $0.05 to $2.67).

CONCLUSION

This study evaluated popular eye health supplements publicly available on Amazon Marketplace. The findings of this study help both patients and physicians better understand the safety and efficacy of these products so they may make more informed choices when supporting their eye health with commercially available supplements. .
