Anearsighted eye. a certain very nearsighted person cannot focus on anything farther than 36.0 cm from the eye.
consider the simplified model of the eye described in exercise. if the radius of curvature of the cornea is 0.75 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described in exercise, what is the distance from the cornea vertex to the retina? what does this tell you about the shape of the nearsighted eye?
exercise:
curvature of the cornea. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40 and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea's vertex is focused on the retina?
