  1. True
  2. False
Explanation

Answer: A

Extended-wear contact lenses are available for one to six nights or up to 30 days of continuous wear. Soft contact lenses are typically used for extended wear. They are made of flexible polymers that allow oxygen to reach the cornea. A few rigid gas-permeable lenses are also manufactured and authorized for overnight usage. The lens type and tolerance for overnight wear determine the length of continuous wear.
