Find the power of the lens necessary to correct an eye with a far point of...
(a) Find the power of the lens necessary to correct an eye with a far point of 26.1 cm (b) Find the power of the lens necessary to correct an eye with a far point of 46.0 cm.
(a) What power lens would you prescribe for a patient with a far point of 38.6 cm? (b) Repeat, assuming an eye-corrective lens distance of 2.00 cm.
A very myopic man has a far point of 16.9 cm. What power contact lens (in D, when on the eye) will correct his distant vision?
1.) 1.)A nearsighted eye is corrected by placing a diverging lens in front of the eye. The lens will create a virtual image of a distant object at the far point (the farthest an object can be from the eye and still be in focus) of the myopic viewer where it will be clearly seen. In the traditional treatment of myopia, an object at infinity is focused to the far point of the eye. If an individual has a far...
The lens-to-retina distance of a woman is 1.92 cm, and the relaxed power of her eye is 54.6 D. (a) What is her far point? How is the refracting power of a person's eye for distant vision related to their far point and lens-to-retina distance? m (b) What eyeglass power will allow her to see distant objects clearly, if her glasses are 1.80 cm from her eyes?
A person’s vision is myopic; without correction, the far point of her eye is a modest 40 cm. This does come with a benefit of having a near point of 8.0 cm. If she wears a lens that correct her distance vision, what power lens is required? With this lens in place, what is her near point?
What power lens is needed to correct for the farsightedness of a person whose near point is 58.0 cm? (Assume that eye-lens distance is negligible and the normal near point of the eye is 25.0 cm). Answer in diopters please.
Without corrective lenses, a person's far point is 17.2cm and the power of their relaxed eye is 51.2 D. A lens is placed 1.85cm away from the eye. What power will the lens be to allow them to see objects at a distance? Can you explain why the relaxed eye has a power of +51.2? When they are nearsighted shouldn't diopters be negative??
An eye has a lens-to-retina distance of 1.95 cm. The power of the relaxed lens is +52.53 diopters. Calculate its far point distance in METERS. Tip: Be sure to do any algebra and units conversions as needed before submitting your answer.
A relaxed eye has a focal point of 18.3 mm causing nearsightedness. What power of lens is required to correct the person's vision if the distance from the lens to the retina is 2 cm?
