Problem 25.16: Ordinary eyeglasses. ? Item 1:? Constants ? Part A Ordinary glasses are worn in front of the eye and usually 2.0 cm in front of the eyeball. Suppose that a nearsighted person with a far point of 110 cm uses ordinary glasses to correct her vision of faraway objects What eyeglass power will give her a sharp image of objects at infinity? (Do not ignore the distance between the eye and the glasses.) Express your answer in diopters...

Sometimes a person cannot clearly see objects close up or far away. To correct this type of vision, bifocals are often used. The top half of the lens is used to view distant objects and the bottom half of the lens is used to view objects close to the eye. A person can clearly see objects only if they are located between 44 cm and 194 cm away from his eyes. Bifocal lenses are used to correct his vision. What...

An optometrist tests a person and finds that without glasses, he needs to have his eyes 15.0 cm from a book to read comfortably and can focus clearly only on distant objects up to 2.75 m away, but no farther. A typical normal eye should be able to focus on objects that are between 25.0 cm (the near point) and infinity (the far point) from the eye. (a) What type of correcting lenses does the person need: single focal length...

please help with part 2
A pair of glasses is designed for a person with a far-point distance of 5 m so that she can read street signs 32.5 m away. (The far-point distance is the distance from the eye at which you are just able to properly focus a distant object.) (a) If the glasses are to be worn 1.0 cm from her eyes, what is the needed focal length? -5.90 m You are correct. Your receipt no. is...
