Goji berry (Lycium barbarum), also known as wolfberry, has a long-standing history in traditional Chinese medicine for supporting eye health. Recent scientific research provides some validation for its use in this context. Goji berries are rich in antioxidants, particularly zeaxanthin, a carotenoid that is concentrated in the macula of the human eye and plays a protective role against age-related macular degeneration (AMD).

Several clinical and preclinical studies have investigated goji berry's effect on eye health. A 2014 randomized controlled trial published in Optometry and Vision Science found that dietary supplementation with goji berry increased plasma zeaxanthin levels and protected against hypopigmentation and soft drusen accumulation in the macula of elderly participants, suggesting a potential role in AMD prevention. Animal studies also indicate that goji berry extract may protect retinal cells from oxidative stress and apoptosis.

Despite these promising findings, the body of evidence remains moderate. Most human studies are small and of short duration, and not all results are conclusive. Nevertheless, there is a reasonable scientific basis—supported by both the presence of key nutrients and some clinical research—for the use of goji berry in supporting eye health, particularly in the context of age-related ocular changes.
