a. A corrective lens for nearsightedness with a focal power of -6 diopters is constructed from the material
which has an index of refraction of 1.6. In order to see the effect in the eye, calculate the change of
image distance when the corrective lens is placed 5 cm in front of the eye model. This distance is not
b. Because the material can also be used in contact lenses, calculate the change in image distance if the
distance between the eye model and corrective lens is negligible. Since we are correcting
nearsightedness, consider the object being seen as far away from the eye....
