A certain very nearsighted person cannot focus on anything further than 36 cm from the eye. Consider the simplified model of the eye where the vitreous humor and the lens all have a refractive index of 1.4, and refraction occurs at the cornea, whose vertex is 2.6 cm away from the retina. If the radius of curvature of the cornea is 0.75 cm, when focusing on an object 36 cm away from the cornea vertex, and the index of refraction is as described above, what is the distance from the cornea vertex to the retina? What does this tell you about the shape of the nearsighted eye?
