13(b)(i) A student in a lecture theatre can not read comfortably from a book at a normal distance without a pair of spectacles. What eye defect has this student?
Model answer
The eye defect the student has is long sightedness (hypermetropia). The lens is unable to adjust itself to become thick enough for looking at close objects, so rays are not bent inwards enough to reach the retina before meeting.
