Lens

(En español: Cristalino)

Say: lenz

The lens is the part of the eye that focuses on what you see. Even though you can't feel it, the lens moves and changes, depending on what you're looking at. When you look at a boat way out in the ocean, the lens gets thinner, and when you look at a page in a book, the lens gets thicker.
