Explanation

(a) Vasantha was suffering from an eye defect called hypermetropia (long-sightedness or far-sightedness) in which a person cannot see the nearby things clearly (though he or she can see the distant things clearly).
(b) (i) Low converging power of eye lens (because of eye lens being less convex or less thick).
(ii) Eye-ball being too short (because of which the distance of retina from the eye lens is less than normal).
(c) The doctor recommended convex lenses for the spectacles of Vasantha. This is because convex lenses are converging lenses which will increase the converging power of the convex eye lenses.
(d) No, Vasantha does not have to wear these spectacles all the time. She has to wear these spectacles only while reading, writing, sewing, etc. (because only her near vision is defective).
(e) Mrs. Sharma displayed the values of (i) Awereness, which means having knowledge of a situation or facts (because she knew that Vasantha's eye defect can be rectified by a using sepctacles) (ii) Concern for others (to mitigate their suffering), and (iii) Kindness and generosity (because Mrs. Sharma bought spectacles for Vasantha by spending her own money).
