Silmad

Silmad are the Estonian word for eyes. As sensory organs, eyes are responsible for sight, allowing individuals to perceive light, color, and depth. The human eye is a complex biological structure that functions much like a camera. Light enters the eye through the cornea, a transparent outer layer, and then passes through the pupil, an opening in the iris. The iris, a colored muscular diaphragm, controls the size of the pupil, regulating the amount of light that enters.

Behind the pupil lies the lens, which focuses light onto the retina at the back of the eye. The retina contains photoreceptor cells called rods and cones. Rods are responsible for vision in low light conditions, while cones detect color and detail. Signals from the rods and cones are transmitted through the optic nerve to the brain, where they are interpreted as images. The intricate interplay of these components enables the remarkable sense of sight.
