Optometrist Registration study guide
Optometrist Registration · Work through your exam, one topic at a time.
The Optometrist Registration Examination is the assessment pathway tied to registration with Singapore's Optometrists & Opticians Board (OOB). Under the Optometrists and Opticians Act framework administered by OOB, all optometrists and opticians providing services to the public in Singapore are required to be registered with the Board and to hold a valid Practising Certificate. The examination exists to satisfy the Board that a candidate's knowledge and competence meet the standard expected of a registered optometrist before registration and, subsequently, a Practising Certificate are granted. The published scope is divided into two equally weighted domains: Optometry (about 50 per cent) and Opticianry (about 50 per cent). Topics on this exam: Optometry and Opticianry. The Optometrist Registration study guide has 2 sections and about 908 words.
01Optometry: Refraction, Binocular Vision and Clinical Decision-Making
The Optometry domain tests whether you can turn a measurement into a defensible clinical decision: convert findings into a prescription, interpret binocular status, and recognise when a patient must be referred rather than refracted again. Registration papers weight applied optics and ocular health roughly equally, so a correct calculation attached to the wrong management plan earns little credit. A prescription can be written in plus-cylinder or minus-cylinder form; both describe the same lens. Transpose by adding the cylinder to the sphere, reversing the cylinder sign, and rotating the axis by 90°.

Opticianry tests the translation of a written prescription into a wearable, standards-compliant pair of spectacles. Questions favour small dispensing decisions - decentration, vertex distance, fitting height - that alter the prismatic effect or the cosmetic result the patient actually experiences. Distance and near PDs differ; using a distance PD for a near-only pair induces base-out prism in both eyes. Prismatic effect by decentration follows Prentice's rule: P (Δ) = c (cm) × F (D).
