Optical Technician Course

Lesson 1 • Vergence and Wavefront Concepts

Introduces vergence as the foundational metric for lens power. Students use vergence calculations to predict how lenses redirect light.

Lesson 2 • Reflection and Refraction Principles

Examines how light bends and bounces at material boundaries. Connects Snell's law to real lens behaviour students will encounter daily.

Lesson 3 • Optical Aberrations Overview

Identifies common aberrations that degrade image quality. Prepares students to recognise aberration symptoms in finished lenses and instruments.

Lesson 1 • Refractive Conditions and Correction

Explains myopia, hyperopia, astigmatism, and presbyopia in terms of focal point errors. Each condition maps directly to the corrective lens powers students fabricate.

Lesson 2 • Posterior Segment and Visual Pathway

Describes retina, optic nerve, and visual cortex pathways from light to perception. Understanding the visual pathway contextualises refractive and neurological conditions.

Lesson 3 • Common Anterior Segment Conditions

Identifies dry eye, conjunctivitis, keratoconus, and cataract as conditions affecting optical management. Technicians recognise symptoms requiring practitioner referral.

Lesson 4 • Glaucoma and Posterior Conditions

Covers glaucoma, macular degeneration, and diabetic retinopathy as conditions with optical and low-vision implications. Technicians support monitoring and low-vision aid dispensing.

Lesson 1 • Multifocal and Progressive Lens Design

Explains bifocal, trifocal, and progressive addition lens (PAL) construction. Students identify design zones and understand power progression across the lens.

Lesson 2 • Lens Coatings and Treatments

Surveys anti-reflective, scratch-resistant, photochromic, and polarised coatings. Students match coating options to patient lifestyle and prescription needs.

Lesson 3 • Lens Forms and Geometry

Describes spherical, cylindrical, and toric lens surfaces and their curvatures. Provides the geometric vocabulary needed for all lens fabrication tasks.

Lesson 4 • Lens Materials and Properties

Compares optical glass, CR-39, polycarbonate, and high-index plastics by refractive index and impact resistance. Material selection directly affects lens performance.

Lesson 1 • Lensometer Operation and Calibration

Teaches manual and automated lensometer use to measure sphere, cylinder, axis, and prism. Calibration routines ensure measurement accuracy across all lens types.

Lesson 2 • Retinoscopy and Refraction Basics

Introduces retinoscopy principles and phoropter use for objective refraction. Students understand how technicians support optometrists during refraction procedures.

Lesson 3 • Keratometry and Corneal Measurement

Covers keratometer use to measure corneal curvature for contact lens fitting. Accurate K-readings guide base curve selection and detect corneal irregularities.

Lesson 4 • Instrument Maintenance and Troubleshooting

Establishes cleaning, storage, and routine maintenance protocols for optical instruments. Proper care extends instrument life and preserves measurement reliability.

Lesson 1 • Frame Anatomy and Sizing

Identifies frame components, sizing notation, and material types. Understanding frame anatomy is prerequisite to all fitting and adjustment tasks.

Lesson 2 • Paediatric and Special Population Fitting

Adapts fitting techniques for children, low-vision patients, and occupational needs. Special populations require modified measurement and adjustment approaches.

Lesson 3 • Facial Analysis for Frame Selection

Applies face shape, feature proportions, and skin tone to guide frame recommendations. Systematic facial analysis improves patient satisfaction and optical alignment.

Lesson 4 • Frame Adjustment Techniques

Demonstrates pantoscopic tilt, face-form wrap, and temple bend adjustments. Precise adjustments align the optical centre with the patient's visual axis.

Lesson 1 • Lens Edging and Rimless Mounting

Operates edging equipment to cut lenses to frame shape with correct size and bevel. Rimless and semi-rimless mounting requires precise drilling and notching.

Lesson 2 • Lens Blocking and Surfacing

Explains blocking alloy application, generator operation, and fining sequences. Proper blocking and surfacing produce the prescribed base and cross curves.

Lesson 3 • Lens Verification After Fabrication

Uses lensometer and ruler to confirm power, axis, prism, and optical centre placement. Verification catches errors before lenses are dispensed to patients.

Lesson 4 • Tolerance Standards and Rework

Applies industry tolerance standards for power, axis, prism, and centration. Students identify out-of-tolerance lenses and determine appropriate rework actions.

Lesson 1 • Fitting Assessment Techniques

Applies slit-lamp evaluation, fluorescein pattern assessment, and over-refraction to judge fit. Systematic assessment identifies poor fit before complications arise.

Lesson 2 • Contact Lens Types and Materials

Compares soft hydrogel, silicone hydrogel, rigid gas-permeable, and specialty lenses. Material properties determine oxygen transmissibility, comfort, and wearing schedule.

Lesson 3 • Contact Lens Care and Solutions

Explains multipurpose, hydrogen peroxide, and saline solution systems and their compatibility. Correct care system selection prevents lens deposits and ocular infection.

Lesson 4 • Patient Education for Contact Lens Wear

Structures insertion, removal, and hygiene instruction for new contact lens wearers. Thorough education reduces complication rates and improves patient compliance.

Lesson 1 • Patient Records and Privacy

Covers prescription record retention, patient data privacy obligations, and release protocols. Proper records management supports continuity of care and regulatory compliance.

Lesson 2 • Regulatory and Safety Standards

Applies impact resistance testing, UV transmission, and occupational safety eyewear standards. Compliance with applicable standards protects patients and limits liability.

Lesson 3 • Scope of Practice and Ethics

Defines the optical technician's scope relative to optometrists and ophthalmologists. Ethical boundaries protect patients and maintain professional credibility.

Lesson 4 • Continuing Education and Certification

Outlines certification pathways, continuing education requirements, and professional development resources. Ongoing learning keeps technicians current with evolving optical technology.
