silmäluomelle

Silmäluomelle is a Finnish term that translates to "eyelid" in English. The eyelids are thin, movable folds of skin that protect the eye. They consist of skin, muscle, and connective tissue, and are lined with a mucous membrane called the conjunctiva. The primary function of the eyelids is to shield the eye from foreign objects, dust, and excessive light, as well as to spread tears evenly across the ocular surface, keeping it moist and clean.

Eyelids play a crucial role in maintaining eye health. Blinking, a rapid closing and opening of the eyelids, is an involuntary reflex that lubricates the eye and removes debris. The upper and lower eyelids meet at the corners of the eye, forming the palpebral fissure. Within the eyelids are meibomian glands, which produce an oily substance that prevents tears from evaporating too quickly.

Various conditions can affect the eyelids, ranging from minor irritations like styes and chalazia to more serious issues such as blepharitis (inflammation of the eyelids) and eyelid ptosis (drooping of the upper eyelid). Eyelid anatomy also includes the eyelashes, which help to filter out small particles, and the eyebrows, which direct sweat and rain away from the eyes. The smooth functioning of the eyelids is essential for clear and comfortable vision.
