Eyelid

The eyelid is a protective formation that lies in front of the eyeball and covers it from above and below, and when closed, closes the eye. Each eye has two eyelids covered with thin skin. In the thickness of the skin of the eyelids lies a dense connective tissue plate that gives hardness and shape to the edge of the eyelid (tarsus), the age-old part of the orbicularis oculi muscle, as well as modified sebaceous glands (meibomian glands) of the cartilage of the eyelids. Each eyelid is lined from the inside with conjunctiva and bordered along the edge by eyelashes. Irritation of pain receptors located on the cornea of ​​the eye causes the eyelids to reflexively close. Inflammation of the meibomian gland can cause the development of a chalazion. Anatomical names: eyelid (blepharon, palpebra).

The eyelid is a protective formation that lies in front of the eyeball. It covers the eye from above and below. When the eyes are closed, the eyelid completely covers the eye.

Each eyelid has two layers of skin that cover it. Under the skin there is a dense connective tissue plate that gives the edge of the eyelids shape and firmness. The inside of the eyelids are lined with conjunctiva, and along the edges they are bordered by eyelashes.

Inflammation of the meibomian glands can lead to the development of chalazion, a condition that causes discomfort and pain.

Thus, the eyelid is an important element of the eye protection system and plays an important role in maintaining the health of our eyes.

The eyelid, or Eyelid, is a protective formation that lies in front of the eyeball and covers it above and below. It serves to protect the organ of vision from mechanical damage and infections. The eyelid consists of two layers: epidermis and dermis. Beneath the epidermis is thick connective tissue that gives the eyelid its rigid shape. The epidermis also contains sebaceous and sweat glands, which secrete secretions that protect the skin from drying out and
