Cornea and The Lens BY Lana, Lee, Ross, Bridget and Tasha!

Examples Below there is a detailed picture of the lens and the Cornea.

Introduction The eyes are perhaps the most amazing organs we posses. They are responsible for four fifths of all the information our brain receives.

Lens The lens is located just behind the iris. Its purpose is to focus light onto the retina. In young people, the lens changes shape to adjust for close or distance vision. We are going to do some experiments to show how the lens focuses light onto the retina.
