Can a myopic person have the far point of his eye less than 25 cm? if not why? if its far point is less than 25cm then the person should become presbiopic? Please explain with proper reason.

myopia is short sightedness.
person is unable to see far objects.that is far point shifts from infinity to nearer point.
but if nearpoint shifts nearer than 25 cm. that means person is also suffering from hypermetropia.
so person can not see far objects as well as near objects.
so he has to use bifocal lens to correct this defect.
upper one should be for seeing far objects:convex lens.:plus power
lower one is for seeing near objects:concave lens: minus power
