Sighted

Sighted refers to the condition of being able to see. It is the opposite of blindness, which is the absence or severe impairment of vision. The ability to see is a complex process involving the eyes, optic nerves, and the brain. Light enters the eyes and is focused onto the retina, where specialized cells called photoreceptors convert the light into electrical signals. These signals are then transmitted through the optic nerve to the brain, which interprets them as images.

The degree of sight can vary greatly. Some individuals have perfect 20/20 vision, meaning they can see clearly at a distance of 20 feet what an average person can see at that distance. Others may have refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism, which can be corrected with glasses or contact lenses. Vision impairment can also occur due to various eye diseases or conditions, such as glaucoma, cataracts, or macular degeneration, which may not be fully correctable.

Maintaining good vision involves regular eye check-ups and protecting the eyes from injury and excessive UV exposure. Nutritional factors, such as consuming foods rich in vitamins A, C, and E, and omega-3 fatty acids, are also considered important for eye health. Understanding one's own vision status and seeking appropriate care are essential for individuals who are sighted.
