An Alligator's eyes are adapted to see underwater because half the time they live underwater. They catch their food underwater, bathe themselves underwater, and they can sometimes nap there. An Alligator has an extra eyelid on their eyes that is clear (almost like a contact lense) to see clearly underwater without letting any fluid gettting into their eyes.

What is the protective cover on the frog's eye that helps it see underwater?
Crocodilians have a transparent nictating membrane which serves as a secondary eyelid. This inner eyelid moves from the sides while the outer eyelid moves up and down. When this transparent eye-lid is engaged, it does limit visual ability somewhat, especially in muddy, darker water. However, it protects the main eye from damage that may be caused by debris in the water (or even during scuffles with fellow crocodilians). When visual ability is limited, crocodilians have a keen sense of smell to help back them up.

The nictitating membrane is a translucent membrane at the bottom of the eye that can be pulled up right across the eye. It is not an eyelid because the frog can still see when the membrane is raised. It is used when swimming or when insects are swarming around the frog's eyes, and also for keeping the eyes moist when it is windy.

Platypuses have two eyelids for protection. One is used the same way as humans use theirs, to help moisten the eyeball, but the other one is used for protection specifically when the platypus is hunting underwater. Platypuses close their eyes underwater and the second eyelid helps protect the platypus's eyes from sediments they stir up as they shovel in the mud for invertebrates and crustaceans.
