This article is about the development of artificial retinas and ways to make someone not have to succumb to macular degeneration. There are different ways that scientists are attempting to make this happen. Some are using signaling molecules while others are trying to put broken genes into retina cells to get it to work again. The most bizarre is putting a camera in the eye.

Knowledge Issues

1. How practical is this new technology that is using cameras? It is very expensive and still in the just beginning stage.

2. To what extent could the process of obtaining artificial retinas be harmful to the patient? There could be radiation from the glasses that use wifi to connect with the camera in the retina. There could be other hamrful things.
