You can’t see clearly underwater with the naked eye, but you can if you wear a face mask or goggles (with air between your eyes and the mask or goggles). Why is there a difference? Could you instead wear eyeglasses (with water between your eyes and the eyeglasses) in order to see underwater? If so, should the lenses be converging or diverging? Explain.

One of the inevitable consequences of aging is a decrease in the flexibility of the lens. This leads to the farsighted condition called presbyopia (elder eye). Almost every aging human will experience it to some extent. However, for the myopic person, at some point, it is possible that far vision will be limited by a subpar far point and near vision will be hampered by an expanding near point. One solution is to wear bifocal lenses that are diverging in the upper half to correct the nearsightedness and converging in the lower half to correct the farsightedness. Suppose one such individual asks for your help. The patient complains that he can't see far enough to safely drive (his far point is 120 cm) and he can't read the font of his smart phone without holding it beyond arm's length (his near point is 81 cm)! Prescribe the bifocals that will correct the visual issues for your patient. 1)Calculate the power of the upper half of the bifocals. (Express your answer to three significant…

(b) A second positive lens is placed to the right of the first. Light emerges from the second lens in a parallel beam of diameter dy 3.6 mm. Thus the combination of lenses acts as a beam expander. Find the focal length of the second lens. Find the distance between the lenses.
A student's uncorrected near and far points are at 9.0 cm and infinity, respectively. She looks through a meniscus-shaped lens as shown in the figure. The absolute value of the radius of curvature is 2.4 cm on the side of the lens near her eye, and 2.6 cm on the side away from her eye. The index of refraction of the lens is 1.4. What is the closest an object can get to the lens and still be clearly visible to the student? [You may assume that the lens is very close to her eye.] eye 3.5 cm 78.0 cm 10.2 cm 8.1 cm 2.3 cm
