How Does the Retina Process Images?

The retina is among the many important parts of the eye. It is the light sensitive, innermost tissue layer that works together with the eye’s optics such as the lens and cornea to create the various images we see in our everyday lives.

Despite being a thin layer of tissue, there is a fascinatingly intricate process involved in how the retina processes light and images. The retina is packed with numerous cells that are each sensitive to light and fall into one of two categories: rods and cones. The former is responsible for processing monochrome (black and white) vision, particularly under poor lighting conditions while the latter process color and are responsible for visualizing finer details. The cones are tucked away in a part of the retina known as the fovea, which plays a role in keeping your central vision sharp.

When the rods and cones of the retina are exposed to light, the light goes through a conversion process where it becomes an electric signal that is sent over to the brain through the optic nerve. It is then up to the brain to process the information received by this signal and turn it into the various images an individual will come across throughout his or her day.
