What is the object distance when a myopic person with a far point of 155 cm, can see near images clearly at 20 cm from the eye?

Ex2: A very myopic person has a near point of 8 cm, and a far point of 20 cm. What power lens does he need to see clearly at a distance? What is his new near point with this vision correction?
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?
(1.) Nearsightedness (a.) A nearsighted person has a far point that is 323 cm from her eye. Her lens in a pair of glasses is 2 cm in front of her eye. What focal length is required to cast the image of a far-away object at her far point? (b.) If these glasses are used to view an object 525 cm from her eye, where do her glasses cast the image? In both cases, quote your distance as measured from...
The near point (the smallest distance at which an object can beseen clearly) and the far point (the largest distance at which anobject can be seen clearly) are measured for six differentpeople. near point () far point () Avishka 40 Berenice 30 300 Chadwick 25 500 Danya 25 Edouard 80 200 Francesca 50 a) Which, if any, of these people are nearsighted(myopic)? b) Which, if any, of these people require bifocals to correcttheir vision? c) Which, if any, of these...
1. When a nearsighted person looks at an object that is in the distance with their glasses on, the image that is produced should be Select one: a. at infinity b. at their eye' s near point c. at their eye's far point d. approximately 25 cm from their eye 2. The power of a lens Select one: a. the same as the magnification of the lens b. is the reciprocal of the focal length (when f is in meters)...
If a hyperopic eye has a near point of 200 cm and a myopic eye has a far point of 200 cm. Which eye requires a focal length of greater magnitude ? - Myopic - Hyperopic - Same Please show full solutions.
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?
A myopic man has a far point of 190 cm. Randomized Variables do = 190 cm What power contact lens in D (when on the eye) will correct his distant vision?
A near-sighted person has a far point of 80 cm. A) What kind of corrective lens the person will need if the lens is to be placed 1.5 cm from the eye? The answer is not 78.5, 80 or -1.27 B) What would be the power of the contact lens needed? Assume distance to contact lens from the eye to be zero.
A child's far point is 129 cm and her near point is 15.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the child's eyes are identical, with each retina lying 1.80 cm from the eye's "thin lens." (a) What is the power, P, of the eye when focused upon the far point? (Enter your answer in...
