Research suggests that saffron extract and its active constituents, particularly crocin and safranal, may support eye health across several conditions, including age-related macular degeneration, glaucoma, diabetic retinopathy, and retinitis pigmentosa. The evidence base consists primarily of narrative and systematic reviews alongside a smaller number of randomized controlled trials, with the reviews drawing on both preclinical data — showing antioxidant, anti-inflammatory, and neuroprotective effects in laboratory and animal models — and early human trial data suggesting improvements in measurable visual function outcomes such as retinal response density and flicker sensitivity. Studies indicate that saffron's proposed mechanisms include reducing oxidative stress in retinal tissue, protecting retinal ganglion cells from damage, and, in the context of glaucoma, offering neuroprotective effects that may complement but do not replace standard pressure-lowering treatments. The overall direction of the literature is supportive, but reviewers consistently note that the existing clinical trials are limited in sample size and duration, and that larger, longer, well-controlled trials are needed before firm conclusions about efficacy can be drawn.
