Probably not, but earthworms have eyes like snails that is only sensitive to light and darkness as how did they know that where they are at the particular place, even on ground (light) or in the ground (darkness). During rain the climatic condition changes to wet and almost dark so, earthworms have eyes just like snails which are sensitive to light and darkness. Some earthworms have eyes like insect so from their protection but they cannot see clearly as they always use to live underground.
