Single eyelid is a condition in which the eyelid has no crease when the eye is open. This is because there is no attachment of the eyelid muscle to the skin of the eye. When looking at the front, the eyelid will appear as a single flat sheet, without the crease like double eyelids. This condition is common in Asians, especially in East Asian countries such as China, Japan, and Korea.

Single eyelid is not considered abnormal, but is a genetic trait that is passed down from generation to generation. Some people may think that it makes the eyes look small or sleepy all the time.

Symptoms may include eye irritation, tearing, red eyes, and in severe cases, corneal infection.
