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. Specialized cells called photoreceptor cells receive the light and convert it to the neural signals. The cone cells and rod cells are two different types of photoreceptors. The cone cells are responsible for colored vision, and rod cells are responsible for visualization in the presence of very less light.
