Question

A myopic person has a normal near point. He/she uses spectacle, of appropriate type and focal length, to correct the defect but, needs to remove the spectacles while -

• A. driving a vehicle.
• B. observing the moon.
• C. reading a book.
• D. doing all of the above.

Answer 1

The correct option is C reading a book.

For driving a vehicle, it is required to see other vehicles which are at far distant.

Also, the moon is at far distant.

Therefore, the person must use the spectacle as he/she is suffering from myopia(nearsightedness) in which he/she finds difficulty in observing far objects clearly.

The person has a normal near point and so, the person can read without any help from the spectacle. Rather, if he/she uses it, he/she won't be able to read clearly as this will cause a lot of strain on the ciliary muscles.

Hence, option $\left(C\right)$ is the correct answer.
