A person cannot see distinctly objects kept beyond 2 m. This defectcan be corrected by using a lens of power(a) + 0.5 D(b) – 0.5 D(c) + 0.2 D(d) – 0.2 D
Question
Solution 1
The person is suffering from myopia or nearsightedness, a condition where the person can see nearby objects clearly but distant objects appear blurry.
To correct this defect, we need a diverging or concave lens. The power of the lens is given by the formula:
P = 1/f
Where: P = power of the lens
