Lesson 2 • Lens Fundamentals

Introduces lens types, optical properties, and basic prescription concepts. Grounds students in lens knowledge before production and finishing chapters.

Lesson 3 • Manufacturing Process Overview

Maps the end-to-end production workflow from raw material to finished product. Orients students to the sequence covered in depth throughout the course.

Lesson 4 • Core Frame Materials

Surveys plastics, metals, and natural materials used in frame production. Links material properties to manufacturing method selection.

Lesson 1 • Supplier Evaluation and Management

Provides frameworks for auditing suppliers, managing lead times, and maintaining approved vendor lists. Supports consistent material quality across production runs.

Lesson 2 • Lens Blank Sourcing

Explains lens blank types, optical-grade standards, and supplier qualification. Ensures students can specify and receive correct blanks for downstream processing.

Lesson 3 • Hardware and Component Procurement

Addresses hinges, screws, nose pads, and decorative hardware sourcing. Links component specifications to assembly quality and product durability.

Lesson 4 • Plastic Material Specifications

Details acetate sheet grades, injection-moulding resins, and nylon formulations. Teaches how to read and apply material data sheets in production planning.

Lesson 1 • CAD Modelling for Frames

Introduces 3D CAD workflows for frame front, temples, and hinges. Models created here feed directly into CNC machining and 3D printing processes.

Lesson 2 • Design Validation and Sign-Off

Establishes the review process for approving prototypes against design intent and regulatory safety requirements. Prevents costly changes after tooling is produced.

Lesson 3 • Ergonomics and Fit Standards

Applies anthropometric data to frame sizing, bridge fit, and temple length. Ensures designs meet comfort and fit requirements before prototyping begins.

Lesson 4 • Rapid Prototyping Methods

Covers 3D printing, CNC milling, and hand-crafted mock-up techniques for prototype creation. Enables fast design iteration before committing to production tooling.

Lesson 1 • Acetate Sheet Cutting

Covers band saw, laser, and die-cutting methods for extracting frame blanks from acetate sheet. Correct cutting technique minimises material waste and edge defects.

Lesson 2 • Hinge Insertion and Temple Assembly

Covers hinge routing, heat insertion, and mechanical fastening methods for attaching temples. Correct hinge installation determines long-term frame durability and function.

Lesson 3 • Barrel Tumbling and Polishing

Details tumbling media selection, cycle times, and polishing compound use for acetate frames. Proper tumbling produces the smooth, glossy surface expected in finished eyewear.

Lesson 4 • Injection Moulding for Eyewear

Explains mould design, injection parameters, and cycle optimisation for plastic frame components. Injection moulding enables high-volume production of complex geometries.

Lesson 1 • Metal Frame Assembly

Covers hinge soldering, nose pad brazing, and screw assembly for complete metal frames. Proper assembly sequence ensures alignment and prevents component damage.

Lesson 2 • Forming and Bending Operations

Teaches CNC bending, press forming, and hand-forming techniques for temples and fronts. Correct forming produces accurate geometry without stress cracking or distortion.

Lesson 3 • Surface Preparation and Plating

Details degreasing, polishing, and electroplating processes for metal frames. Surface preparation quality determines plating adhesion, appearance, and corrosion resistance.

Lesson 4 • Welding and Soldering Techniques

Explains laser welding, resistance welding, and silver soldering for joining frame components. Joint quality directly affects frame strength and long-term reliability.

Lesson 1 • Lens Surfacing Operations

Covers generator cutting, fining, and polishing cycles for producing prescription curves. Each step builds on the previous to achieve the required optical surface quality.

Lesson 2 • Tinting and Photochromic Processing

Covers dye bath tinting, gradient techniques, and photochromic activation processes. These processes expand product range and meet customer prescription requirements.

Lesson 3 • Lens Edging and Glazing

Explains tracer operation, edging machine setup, and lens insertion into frames. Correct edging produces a secure, optically centred lens-frame fit.

Lesson 4 • Anti-Reflective and Hard Coating

Details vacuum deposition and spin-coating processes for AR and hard coatings. Coating quality affects optical performance, scratch resistance, and product longevity.

Lesson 1 • Frame and Lens Integration

Covers full-rim, semi-rimless, and rimless mounting methods for integrating lenses into frames. Correct mounting prevents lens stress, optical decentration, and cosmetic defects.

Lesson 2 • Frame Adjustment Techniques

Teaches temple angle, pantoscopic tilt, and nose pad adjustment for proper fit. Accurate adjustment ensures wearer comfort and correct optical performance.

Lesson 3 • Engraving and Branding

Covers laser engraving, pad printing, and hot stamping for applying brand marks and model information. Consistent branding supports traceability and brand identity.

Lesson 4 • Cosmetic Finishing Operations

Details buffing, polishing, and cleaning steps applied after assembly to achieve final appearance. Cosmetic finishing is the last production step before quality inspection.

Lesson 1 • Regulatory and Safety Compliance

Addresses product safety standards, restricted substance requirements, and conformity marking. Compliance ensures market access and protects end users from harm.

Lesson 2 • Non-Conformance and Corrective Action

Provides a structured process for logging defects, root cause analysis, and corrective action implementation. Effective non-conformance management reduces recurring quality failures.

Lesson 3 • Cosmetic and Dimensional Inspection

Teaches visual inspection criteria, measurement tools, and acceptable quality level sampling. Consistent inspection prevents cosmetic defects from reaching the customer.

Lesson 4 • Optical Performance Testing

Covers lensometer use, prism measurement, and UV transmittance testing for finished lenses. Optical testing confirms that lenses meet prescription and safety specifications.
