7. Assume that a person's lenses have a refractive power of 2.75 diopters that allow the person to focus on an object that is 25 cm from the eye. The glasses are 25 cm from the eye. The glasses are 2.00 cm in front of the eyes. a) Is the near point of this person greater or less than 57.0 cm? What is the distance from the near point when the glasses have a refractive power of 2.53 diopters? Explain b) find the near point of this person.

A person's prescription for his new bifocal eyeglasses calls for a refractive power of -0.0600 diopters in the distance-vision part and a power of 1.05 diopters in the close-vision part. Assuming the glasses rest 2.00 cm from his eyes and that the corrected near-point distance is 25.0 cm, determine the near and far points of this person's uncorrected vision.

Contact lenses are placed on the eyeball, so the distance from the eye to an object (or an image) is the same as the distance from the lens to the object (or the image). If a person can see distant objects well, but has a nearpoint of 53.0 cm instead of the usual 25.0 cm, what power of contact lenses are needed (in diopters)? The same person now wants to wear glasses instead; they are 1.90 cm in front of...

2. Correcting vision: quantitative. Corrective lenses work because the lens bends light such that it, combined with the eye itself, light forms a clear image on the retina. Another way to think about this is that the corrective lens (glasses) form an image of the object at a location where the eye can see clearly without corrective lenses. For a nearsighted person viewing an object very far away (object at infinity), the lens corrective lens creates an image at the...
