Apple of my Short Sighted Eye

After our discussion in class about the dynamics of the eye and how they are able to see color, was interested in learning more about how eyes work. I learned that eyes can be different sizes and this leads to short and long sightedness. When eyes are too short, light goes through the lens and focuses behind the retina. This means that they are long sighted and have to focus more than they should do, especially on things that are close up. When eyes are too long, light goes through the lens and focuses in front of the retina. This means that they are short sighted and that they cannot see things clearly if they are far away. Normally light is focussed by the lens to form a sharp image on the retina. Long sightedness and short sightedness can run in families and be genetically passed on. Long sightedness and short sightedness can be corrected by glasses or contact lenses. They act as an extra lens, besides the lens in the eye, that focus the light correctly to the retina. The many parts of the eye work together to allow us to correctly see and observe the world around us.
