Peripheral Vision is the ability to see movement and objects outside of your direct line of vision. It is the work of rods or nerve cells located outside the macula of the retina. These rods are responsible for your night vision and low-light vision but are insensitive to color. Peripheral Vision is broken down into 3 parts; far-peripheral vision, mid-peripheral vision, and near-peripheral vision. These segments are pretty self-explanatory. Far-peripheral vision is your vision at the edge of your field of view; mid-peripheral vision is your view in the middle and near-peripheral vision is the vision just next to your center gaze.
Most people do not value their peripheral vision until they start to lose it. The loss of peripheral vision is called tunnel vision. Peripheral Vision is weaker in humans than any other species. This is due to the thickness of the receptor cells on the retina. The retina is a coating of tissue located in the back of the inner eye that converts light images to nerve signals and sends them to

Another common eye disease you could get is Retinitis Pigmentosa. Retinitis Pigmentosa is a genetic condition, meaning it travels down through generations. The condition of Retinitis Pigmentosa varies on each person. Some symptoms of Retinitis Pigmentosa are the loss of night vision or night blindness, or problems with color vision. Some people may have trouble seeing the difference in some colors with Retinitis Pigmentosa. Night blindness means you take longer to adjust to the dark, you may fall over objects or have trouble driving in the dark. You may also find it difficult to see in movie theaters or dim rooms. Retinitis Pigmentosa is diagnosed and measured by a few simple test such as genetic testing, electroretinography, Visual field testing, and Optical Coherence Tomography. Genetic testing is a test that looks at your blood and other tissues to see if you have genes that are linked to a disease. It may also help decide how crucial the disease
