What is the unreflective layer of the eye?

The unreflective layer of the eye refers to the retinal pigment epithelium (RPE), which is a layer of cells located between the retina and the choroid. This layer is crucial for supporting photoreceptors by absorbing excess light, preventing scattering, and recycling visual pigments. Additionally, it plays a role in maintaining the health of retinal cells and protecting against oxidative stress. The RPE is essential for optimal visual function.
