A person can see objects clearly only if they are between 22cm and
82cm away.
Assuming that the person is given glasses which sit 2cm from the eyes, what focal
length should the glasses be to see things far away clearly?
Homework Answers
Hi!
The persons band of vision is from 22-82 cm. This means that this distance will allow him to see clearly. anything above 82 cms is considered far away for the person to see. So the correcting glasses must have a focal length larger than 82 cms to see things at a distance clearly. Since it is worn 2 cm from the eyes, thus the glasses must have a focal length greater than 84 cms to percieve the image clearly.

A person is nearsighted and can clearly focus on objects that are no farther than 3 m away from her eyes. She borrows a friend's glasses but the borrowed glasses make things worse; that is, the person can now focus only on objects that are within 2.25 m away. What is the focal length of the borrowed glasses?

If Mark is unable to see objects clearly when they are placed beyond 0.5m away, (a) is he near-sighted or far-sighted? (b) What should be the focal length of a pair of contact lenses prescribed to correct this problem? (c) If instead he wears eye-glasses, and they are to sit 2.0cm in front of his eyes, what prescription should they be?

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...

Velma is extremely nearsighted, and has difficulty seeing anything which is further away than 1.5 meters from her face if she isn't wearing her glasses. Dexter also wears glasses, which correct his farsightedness; he can only see objects clearly when they are more than 50 cm from his eyes. Assuming that each of them wears glasses which are 1.5 cm from their eyes, and that a person with normal vision has a near point of 25 cm and a far...

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 36 cm and 160 cm away from her eyes. Bifocal lenses are used to correct her vision. What...
