Don't know what you mean by 'serious.' Do you mean 'serous' as in fluid-filled?
The membrane that can cover over a frog/toad's eyes (and other amphibian, reptile, even mammal species) is known as a 'nictating' membrane. It is there to protect against fluid and debris from coming into contact with the corneal surface of those eyes.

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.
The nictitating membrane is part of a frog's eye. It is just above the lower lid and acts as a protective third eyelid.
The nictitiating membrane protects the eye so frogs can see in water.
The cornea is located in the middle of the eye. It covers the iris and pupil. It is transparent and allows light into the eye.
The nictitating membrane is the transparent layer the covers the outside of a frogs eye. Frogs have a so-called Nictitating membrane, which they can slide over their eyes for protection. They do this while jumping and swimming.

The frog's eye has a nictitating membrane that covers the eye and allows the frog to see underwater with ease.
A mucous membrane covers the inner surface of the eyelid. It is moist and since it makes mucous, the eyelid moves easily over the eye.
The conjunctiva is a thin, clear, mucous membrane that covers the sclera, or white part of the eyeball, and lines the inside of the eyelids. It lubricates and protects the eye.
They have a transparent membrane that covers the eye when they submerge.
The medical term for the mucous membrane that lines the inner surface of the eyelids and covers most of the anterior surface of the eye is "conjunctiva."
Most frogs have a nictitating membrane. It's a sturdy film that covers and protects the eye while the frog is underwater.
The sclera is part of the eye and is better known as the white part of the eye. The iris is the colored part of the eye. The sclera is actually a membrane that covers the outside of the eye.
The membrane is called the haw (or third eyelid) and helps to clean and lubricate the eye. It is not normally visible but, if it is, may mean that the cat is under the weather and should be checked by a vet. Hope this helps.
The name of the membrane that covers the organs of the abdomen in a fetal pig is the peritoneum membrane.
