• How Does The Eye Focus?

     

    • You focus light with your cornea and lens.

    • Your curved cornea bends the light into your eye.

    • Your lens changes shape to bring things into focus.

    • When you look at things that are far away, muscles in your eye relax and your lens looks like a slim disc.

    • When you look at things that are close, muscles in your eye contract and make your lens thicker.
