pelisilmä

Pelisilmä, also known as "eyeball" in English, is a term used to describe the visible part of the eye that is not covered by the eyelid. It is a crucial sensory organ responsible for detecting light and enabling vision. The pelisilmä consists of several distinct structures, including the cornea, iris, pupil, and retina.

The cornea is the transparent front surface of the eye that protects the inner structures and helps to focus light onto the retina. The iris is the colored part of the eye that controls the size of the pupil, the central opening that allows light to enter the eye. The retina is a light-sensitive layer of tissue at the back of the eye that contains photoreceptor cells, which convert light into electrical signals that are sent to the brain via the optic nerve.

Pelisilmä health is essential for maintaining good vision. Conditions that affect the pelisilmä include cataracts, glaucoma, and macular degeneration. Regular eye examinations are recommended to detect and manage these conditions early. Proper eye care, including wearing protective eyewear and avoiding excessive screen time, can help maintain the health of the pelisilmä.
