NEED HELP ON #2 A nearsighted pharmacy student has eyes who have a relaxed refractive power of 49 diopters and her retina is 2.3 cm from her lens. 1). If she is nearsighted, what is her far point? If she is far-sighted, what is her near-point? .1804 m 2) Let's say she wants to be able to focus clearly on objects that are from 150 m to 6.5 cm away. What is the power of the corrective lens she should...
A nearsighted person wears contact lenses of refractive power -6.0 D. What is her far point? 17 cm 6.0 cm -17 cm -4.0 cm -6.0 cm
(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...
A person has a near point of 14 cm and a far point of 82 cm. Is the person nearsighted or farsighted? What focal length corrective lens will allow this person to read the whiteboard from the back of a large classroom? Are the corrective lenses converging or diverging? What is the power of the corrective lenses?
3) (20 points) A nearsighted person has a far point located only 521 cm from the eye. Assuming the eyeglasses are worn 2 cm in front of the eye, find the focal length needed for the diverging lenses of the glasses so the person can see distant objects.
The far point of a nearsighted person is 6.9 m from her eyes, and she wears contacts that enable her to see distant objects clearly. A tree is 14.8 m away and 2.8 m high. (a) When she looks through the contacts at the tree, what is its image distance? (b) How high is the image formed by the contacts?
The far point of a nearsighted person is 4.9 m from her eyes, and she wears contacts that enable her to see distant objects clearly. A tree is 23.1 m away and 1.6 m high. (a) When she looks through the contacts at the tree, what is its image distance? (b) How high is the image formed by the contacts?
