For the health condition: Eyes (spots before)
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Zeaxanthin is a carotenoid found in high concentrations within the retina of the human eye, particularly in the macula. Its primary scientifically validated use is for supporting overall eye health and for reducing the risk or progression of age-related macular degeneration (AMD). There is moderate-quality evidence that dietary intake or supplementation of zeaxanthin, often with lutein, may increase macular pigment density and support visual function, especially in older adults or those at risk for AMD.
However, the specific use of zeaxanthin for treating or preventing “spots before the eyes” (commonly known as floaters) is not well supported by clinical evidence. Floaters are typically caused by changes in the vitreous humor of the eye and are unrelated to the oxidative damage or macular degeneration for which zeaxanthin has shown benefits. There are no significant clinical trials or robust scientific studies demonstrating that zeaxanthin supplementation can prevent, reduce, or treat eye floaters. Most clinical research focuses on macular health and visual acuity, not on vitreous floaters.
In summary, while zeaxanthin has a scientifically supported role in general eye health and macular protection, its use specifically for “spots before the eyes” is not well validated. The evidence rating for this specific application is low, reflecting a lack of targeted research and clinical support.
