Cheat Sheet
- Refraction Fundamentals and Snell's Law -
Review the core formula n·sin θ = n₂·sin θ₂ to predict how light bends through different ocular media (Source: HyperPhysics, Georgia State University). Note that as refractive index increases, light deviates more toward the normal - crown glass (n≈1.52) bends light more than water (n≈1.33). Use the mnemonic "Air to Dense Bends In" to lock this principle into memory for your optician test.
- Corneal Topography & Lens Fitting -
Understand how corneal curvature measurements, expressed as base curve radius and sagittal height, guide proper contact lens selection (Source: American Academy of Optometry). A flatter base curve yields looser fit while a steeper one increases vaulting - key for lens comfort and corneal health. Remember "Flatter Follows, Steeper Stands Off" when choosing trial lenses during an optical quiz.
- Spherical vs. Cylindrical Correction -
Differentiating sphere (S) and cylinder (C) power is vital: sphere corrects uniform myopia or hyperopia, while cylinder addresses astigmatism at a specific axis (Source: Journal of Optometric Vision Development). Convert cross-cylinder data using J0 and J45 vectors if you encounter complex prescriptions. A quick trick: "Sphere Shapes, Cylinder Aligns" to recall their distinct roles on the optometry practice test.
- Pupillary Distance (PD) Measurement -
Accurate PD, typically 55 - 65 mm in adults, ensures optical centers of lenses align with the eye's visual axis (Source: American Optometric Association). Use a millimeter ruler or a digital pupillometer and verify monocular PD for precise bifocal or progressive lens placement. In your eye care knowledge quiz, remember that a 1 mm error can introduce prismatic imbalance and visual discomfort.
- Optical Aberrations and Corrections -
Familiarize yourself with common aberrations - spherical, chromatic and coma - that degrade image quality (Source: Optical Society of America). Aspheric lens designs reduce spherical aberration, while high-AD lenses and anti-reflective coatings minimize chromatic dispersion. Think "Aspheric Adapts, Coatings Cancel" to boost recall during vision science trivia.
