Good vision depends on the lens, retina, optic nerve, and brain all successfully working together. Visual disorders such as short- and long-sightedness, which can usually be corrected with spectacles, are extremely common. Eye disorders range from mild conjunctivitis to serious disorders such as glaucoma (“green star”).
