Saffron contains unique antioxidants called crocin and crocetin that can cross the blood-retinal barrier—something many common supplements struggle with. Several human trials (including double-blind studies conducted in Italy, Australia, and Iran) have explored how small daily amounts affect visual function.
Here is science in simple language:
-
Improves contrast sensitivity and visual acuity in 90 days (University of L’Aquila trial in 2021)
-
Increases the density of macular pigment — the eye’s natural « sunglasses » (Meta-analysis 2024)
-
Supports healthy retinal blood flow
-
Helps reduce oxidative stress due to exposure to blue light (University of Sydney laboratory study, 2023)
-
Appears to support tear film stability and comfort (Iranian clinical trial)
Most participants in these studies used only 20 mg of high-quality saffron per day — roughly the amount found in 6 to 8 top-quality threads.
