6 lucruri surprinzătoare despre ochi. Ce nu știai despre modul în care funcționează vederea

The human eye is a complex organ that transforms light into electrical signals for the brain to interpret. It begins with light entering through the cornea, which focuses it onto the retina. The retina converts light into signals sent via the optic nerve to the brain, where images are processed. Eye health is influenced by nutrition, particularly vitamins and omega-3 fatty acids. Eye size increases significantly in early life and reaches maximum size in early adulthood. Eye muscles are among the fastest in the body, allowing for quick movements. The retina contains millions of color-detecting cells, enabling the perception of around 10 million shades. Eye color varies due to genetic factors, with brown being the most common. Images are inverted on the retina, but the brain corrects this automatically. Tear production changes with age, often decreasing over time, leading to dry eyes.
