The far point of a myopic person is 120 cm in front of the eye. Calculate the power of the lens required to enable the person see distant object clearly.

Explanation

To solve the problem of determining the power of the lens required for a myopic person whose far point is 120 cm, we can follow these steps:

### Step 1: Understand the Condition of Myopia
A myopic person can see nearby objects clearly but struggles with distant objects. Their far point is the maximum distance at which they can see clearly. In this case, the far point is given as 120 cm.

### Step 2: Identify the Required Image Distance (V)
To enable the person to see distant objects clearly, we need to create an image at their far point. Therefore, the image distance (V) will be -120 cm (the negative sign indicates that the image is formed on the same side as the object, which is typical for virtual images formed by diverging lenses).
