Welcome to Part 3 of our Eye Anatomy blog series! In this post we are going to talk about the Retina and the Optic Nerve.

The Retina:

The retina is a very important part of sight that senses the light that comes into your eyes. It is made up of many cells, one of which is called a photoreceptor. The center of the retina, which is called the macula, is the most sensitive part of your vision, because it has millions of tightly packed photoreceptors in a small area. This densely packed are of photoreceptors makes visual images detailed, just as higher counts of megapixels in a digital camera allow for HD images.

Some common eye conditions and diseases related to the Retina are:

The Optic Nerve:

The optic nerve is the nerve that connects your eye to your brain. It carries the signals that are given off by light hitting the retina. It is made up of more than 1 million never fibers. The optic nerve can be damaged in diseases like glaucoma, which is believed to be caused by high eye pressures.
