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.

∙ 10y agoThe nictating membrane is a translucent membrane on the eye of the frog that closes over the eyeball when the frog is underwater. This helps the frog greatly as it allows it both to see underwater and to protect the eye from debris or bacteria.

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.
