The meibomian glands are sebaceous glands located along the eyelids where the eyelashes are found. Their purpose is to create the oil that makes up a key component of the tear film.

The retina is a thin tissue layer found at the back of your eye. This thin inner lining is located near the optic nerve, which connects your eyes to your brain.

The retina contains photosensitive cells that perceive vision and color at both low and high light levels. An unhealthy retina can affect how you see and process visual information.
