Abstract
A composition according to an embodiment of the present disclosure includes a banaba leaf extract, a guava leaf extract or a mixture thereof. The composition inhibits photooxidation of A2E due to blue light, inhibits a death of retinal pigment epithelial cells induced by blue light, and inhibits a damage to outer nuclear layers of visual cells in an animal model with blue light-induced macular degeneration, and thus can be beneficially used as a composition for preventing or treating macular degeneration and as a health functional food for preventing or alleviating macular degeneration.
