a. A 6 year-old boy with accommodative esotropia has an objective refraction
of +5.00DS in each eye without cycloplegia. If atropine were instilled
before the refraction, what would happen to the objective refraction?
b. An eye has a visual acuity of 6/9 uncorrected. A +1.25D lens improves
the vision to 6/6 and it remains 6/6 with +1.75D. A +2.00D reduces the
vision to 6/9. What is the:
i. value of the manifest hypermetropia? ii. value of the facultative hypermetropia? iii. value of the absolute hypermetropia?
