Statement one focuses on contacts while statement two focuses on glasses. The first statement gives a few examples of why contacts could be more beneficial than glasses (don't fog up/move with your eye). The second statement does not go into details about how glasses could be more helpful, but instead describes different types of glasses that exist.
hope this helps!
