Q. An old man cannot see objects closer than 1m from the eye clearly. Name the defectofvision he is suffering from.
Should the answer be hypermetropia or presbyopia?
Iwrote the answer as prebyopia. Ijust want a confirmation.
presbyopia is also a special kind of hypermetropia. It is old age hypermetropia. It is that defect in which an old person cannot see nearby objects dueto loss of power of accomodation of the eye. It is mentioned in the question that the man is old, so i wrote prebyopia.
You are partially correct but you will not get any mark for your answer. The correct answer is hypermetropia.
Hypermetropia: It is the defect of the eye because of which nearby objects cannot be seen clearly. Image is formed in behind the retina. It is also called Farsightedness.
Presbyopia: It is the defect of eye in which a person cannot see further as well as nearer objects clearly. This defect of vision commonly occurs to old people.
