Questions are based on the following passage: The human eye is the organ that reacts to light. The outer layer of the eye is called the cornea. The cornea has a refractive index (n) of 1.38 and a radius of curvature (R) of 7.8 mm. Air has a refractive index of 1.00, while water has a refractive index of 1.33. The average distance from the cornea to the retina is 17.0 mm. Myopia, or nearsightedness, occurs when rays are focused before they reach the retina, while hyperopia, or farsightedness, occurs when light rays focus behind the retina rather than directly on it.
