szemhéjat

Szemhéjat is a Hungarian word that translates to "eyelid" in English. The eyelids are folds of skin that cover and protect the front of the eye. They are essential for maintaining eye health and facilitating vision.

There are two eyelids, the upper eyelid and the lower eyelid. They are composed of several layers, including skin, muscle, connective tissue, and a thin membrane called the conjunctiva. The muscles within the eyelids allow for blinking, which is a rapid closing and opening of the eyelids. Blinking helps to spread tears over the surface of the eye, keeping it moist and clear of debris. It also protects the eye from foreign objects and bright light.

The eyelids play a crucial role in regulating the amount of light that enters the eye. In bright conditions, the eyelids can partially close to reduce light exposure, while in dim light, they remain more open to allow more light in. They also protect the eye from dust, dirt, and other irritants.

Various conditions can affect the eyelids, including inflammation, infections, and growths. These can range from minor irritations like styes to more serious issues that may require medical attention. The appearance and function of the eyelids can also change with age.
