Power of lens = +1.5
As power is positive, hence the focal length will also be positive .
Therefore the lens is convex lens and the defect of eye if hypermetropia.

power = 1.5 D , D = Dioptres
It is positive means the lens is a double convex lens or plano convex lens.
The eye muscles are not able to focus the images of faraway objects on the retina. The image is being formed behind the retina. The defect is Long sightedness. or hypermetropia or hyperopia. The objects at short distances cannot be seen clearly.
