Summary Introduction
Introduction:
The eye is a sensory organ that detects the light and converts the image into electrical signals, and these signals are transferred to the visual cortex of the brain. The different parts of the eye include sclera, pupil, iris, cornea, lens, and retina. The specialized cells called photoreceptor cells receive the light and convert it to the neural signals.
