Contact lenses are biomedical products designed to help improve vision by being placed directly on the eyeball. Which statement below best explains why a polymer (plastic) should be used over textiles for contact lenses?

• Polymers (plastics) are flexible, do not absorb water and can be clear while textiles are flexible but they absorb water effecting their functionality.

• Textiles are flexible, do not absorb water and will not rust while polymers (plastics) can have a low melting point and tear very easily.

• Polymers (plastics) are not rust resistant and are toxic to the human body while textiles are rust resistant and not very flexible.

• Textiles are flexible and absorb water well while polymers (plastics) will never change shape and can be clear.

Which of the following statements gives the best example of a biomaterial?

• Naturally occurring soil is a biomaterial because it comes from the earth.

• An engineered substance used for a medical purpose is an example of a biomaterial.

• Skin is a biomaterial because it is found on living things.

• Biodegradable plastic can be made into many shapes therefore it must be a biomaterial.
