The abnormality shown in the picture is a larger than normal eyeball, which is a typical characteristic of nearsightedness (myopia). Nearsightedness occurs when the eyeball grows too long from front to back, causing light to focus in front of the retina instead of on it, leading to blurred distance vision. Farsightedness (hyperopia) occurs when the eyeball is too short, causing light to focus behind the retina instead of on it, leading to blurred close-up vision. Astigmatism occurs when the cornea or lens has an irregular shape, leading to distorted vision at all distances. Cataracts and glaucoma are conditions that affect the clarity of the lens or damage the optic nerve, respectively, but they do not cause the eyeball to enlarge.
