If Ram, a myopic person uses spectacles of power $-0.5 \mathrm{D}$ then what will be the distance of far point of his eye?

Mala can see the objects lying between $25 \mathrm{cm}$ and $100 \mathrm{cm}$ from her eye. Her vision can be corrected by using the lens of power $-1.0 \mathrm{D}$. Is the statement true or false?
