The retinal pigment epithelium (RPE) is indeed located in the outer layer of the retina. This layer plays a crucial role in maintaining the health and function of photoreceptors, which are the cells responsible for detecting light. The RPE absorbs excess light to prevent scattering within the eye, which enhances visual acuity. Additionally, it is involved in the process of phagocytizing the outer segments of the photoreceptors, thereby helping to regenerate visual pigments and contributing to the overall photoreceptor functionality.

This layer is essential for the metabolic support of the retina's photoreceptors and helps to maintain the blood-retinal barrier. The importance of the RPE in protecting and supporting photoreceptors underscores its classification as the outermost layer in the retinal structure.
