szemek
Szemek are paired sensory organs that detect light and enable sight. They are part of the visual system and work with neural pathways to produce visual perception. In humans, two eyes provide overlapping fields of view, allowing binocular vision and depth perception.
Anatomy: The eye has three layers—the sclera, choroid, and retina. The front segment contains the cornea, iris,
Function: Light is projected through the cornea, lens, and vitreous body onto the retina, where photoreceptors
Health and variation: Vision can be affected by refractive errors such as myopia, hyperopia, and astigmatism.
