Retina

The retina is a layer of light-sensitive tissue in the back of the eye, containing photoreceptors that detect light before sending signals to the brain to produce images. It plays a fundamental role in vision by allowing us to see in all directions and at different levels of brightness. The retina is also involved in detecting motion, light, and colour. It is essential for proper vision and is used to diagnose and treat a variety of eye conditions, including macular degeneration, retinal detachment, and glaucoma. It is also used in the development of digital cameras and other imaging technologies.
