A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in ...
The top and bottom images produce a dent or projection depending on whether viewed with cross- () or wall- () eyed vergence.

His videos are captioned with language like “this is making you ugly,” “stop ruining your skin,” and “get a smaller nose.” The makeover advice went, and continues to go, viral.
Cone cell. Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in ...
