Question 01. Where is distant light focused in uncorrected myopia with relaxed accommodation? A. Behind the retinaB. At the optic chiasmC. Only on the irisD. In front of the retina

Question 02. Which lens generally corrects myopic blur? A. A converging lensB. A plano lens in every caseC. A prism alone in every caseD. A diverging lens

Question 03. What optical problem characterises hyperopia? A. Insufficient convergence relative to eye lengthB. Complete loss of photoreceptorsC. Corneal infectionD. A retinal tear

Question 04. Astigmatism is associated with what? A. Different refractive power across meridiansB. Identical power in every meridianC. Mandatory optic nerve damageD. Raised pressure in every patient

Question 05. What causes typical presbyopic near difficulty? A. Acute retinal arterial occlusionB. New corneal ulcerationC. Age-related reduction in accommodationD. Sudden loss of the visual cortex

Question 06. Which structure is most associated with detailed central vision? A. Eyelid marginB. Lacrimal sacC. MaculaD. Ciliary muscle alone

Question 07. Why might a child need cycloplegic refraction? A. To measure hearingB. To reduce accommodation during refractive measurementC. To confirm every squint is paralyticD. To replace assessment of ocular health

Question 08. New distortion of straight lines suggests particular concern for which region? A. External eyelid skin aloneB. Lacrimal punctum aloneC. MaculaD. Conjunctival fornix alone

Question 09. What should follow poor acuity despite adequate optical correction? A. Automatic reassuranceB. Repeatedly stronger lenses without reviewC. Investigation of other causes of visual impairmentD. Permanent occlusion without diagnosis

Question 10. Which contact-lens symptom requires prompt assessment? A. Comfortable clear visionB. Painful red eye with reduced visionC. Stable prescription aloneD. Normal blinking
