Do Blind People Dream?

Sight or vision is the capability of the eyes to receive visible light through the retina of each eye to where our nerve receptors send messages to our brain that we translate as colors, hues, and brightness. We have two main receptors in our eyes called cones and rods. Rods distinguish light not color. Cones are responsible for all the colors we see, but are sensitive to dim light, for example it’s difficult to make out colors in poorly lit situations yet you can see the shape of the object. The inability to see is called blindness. Multiple things cause blindness: damage to the eyeball, especially the retina, the optic nerve and strokes. Temporary blindness can be caused by medications.
