Lutein and Zeaxanthin
These carotenoids' concentration in the macula is well-documented in nutrition science. See our full Lutein deep dive and Zeaxanthin article.
Bilberry Extract and antioxidant vitamins
Bilberry Extract, Vitamin C, and Vitamin E all contribute antioxidant support, a well-established category in general nutrition. See our Bilberry guide.
Where the science is strongest — and where it's still general
The presence of Lutein and Zeaxanthin in the macula is well-documented, but how strongly any individual experiences noticeable benefits varies based on baseline nutrition, age, and consistency of use. You can explore the primary literature yourself via the National Eye Institute.
Bottom line
Clear Gaze's formula reflects a reasonable, transparent approach built on nutrients with genuine documentation in eye-health nutrition — not a "miracle" claim, but a defensible ingredient stack. See our overall worth-it review for the full picture.
