- 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…One of the inevitable consequences of aging is a decrease in the flexibility of the lens.

(Express your answer to three significant…An internal lens may now be used to replace the eye's cataract-clouded lens. You may choose this intraocular lens so that you have flawless vision in the distance. Without glasses, will the individual be able to read? Is the power of the intraocular lens more or less than the power of the lens that was removed?
- A person is nearsighted, and the relaxed eye focuses at a distance of 50 cm. What is the strength of the desired corrective lens in diopters? thats the full questionWhen you use a microscope, you may have noticed that you can rotate a "turret" to choose different objective lenses. Explain why the high-powered (magnification) lenses are also in larger mounts.A nearsighted man wears contact lenses of -3.00 diopters. With these lenses, his corrected near point is 25.0 cm. What is his uncorrected near point?
