() Avishka 40 Berenice 30 300 Chadwick 25 500 Danya 25 Edouard 80 200 Francesca 50 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 different people. Which, if any, of these people arenearsighted (myopic)? List the first letter of all correctanswers in alphabetical order. For example, if Avishka and Edouardare the only nearsighted ones, enter AE. Which, if any, of these people requirebifocals to correct their vision? List the first letter all correctanswers in alphabetical order. For example, if Avishka and Edouardare the ones needing bifocals, enter AE. Which, if any, of these people's vision canbe corrected using only converging lenses? List all correct answers inalphabetical order. For example, if Avishka and Edouard are theones whose vision can be thus corrected, enter AE.

Explanation / Answer

Farsighted would be: Edouardo, Berenice, Francesca, and Avishaka. Farsighted means >25cm
So that means Danya and Chadwick are nearsighted.

I don't think any require bifocals

The converging lenses would help Chadwick because he has the biggest difference.
