The Ophthalmic Lenses and Dispensing II Lab is an essential component of the comprehensive course curriculum, designed to provide students with hands-on experience and practical skills in the dispensing of ophthalmic lenses. This lab course focuses on mastering advanced techniques in lens dispensing, frame measurements, lensometry, lens marking, edging, and tinting, equipping students with the necessary competencies for professional practice in optometry, ophthalmology, or opticianry.
Students will engage in a series of structured laboratory sessions covering the following topics:
Dispensing Glass and Frame Measurements: Students will learn how to accurately measure frame dimensions, including Inter-Pupillary Distance (I.P.D.), Frame Pupil Distance (F.P.D.), and apply the Boxing System for proper frame fitting. Practical exercises will enable students to dispense glass lenses effectively, ensuring precise alignment and fit within frames.
Review Lensometer and Lens Marking: Through hands-on demonstrations, students will review the operation of a lensometer and practice marking lenses for monocular, bifocal, and progressive prescriptions. Emphasis will be placed on accurate interpretation and marking of lens powers, cylinder axes, and prism corrections.
Decentration and Blocking: Students will explore techniques for lens de-centration and blocking, essential for ensuring optimal lens alignment and stability during the edging process. Practical exercises will reinforce concepts of lens de-centration and blocking for both single vision and multifocal lenses.
Edging Lens: Through demonstrations and hands-on practice, students will learn both manual (hand) and automated (auto) edging techniques. Techniques for edging rimless and three-piece lenses will be covered, enabling students to produce accurately edged lenses for various frame styles.
Tinting Lenses: Students will explore the principles and techniques of lens tinting for enhancing visual performance and protection. Practical exercises will cover the application of tinting solutions to lenses, ensuring consistent coloration and UV protection properties.
By actively participating in the Ophthalmic Lenses and Dispensing II Lab, students will develop proficiency in advanced dispensing techniques, lensometry, lens marking, edging, and tinting. Through hands-on practice and guided instruction, students will acquire the skills and confidence necessary to excel in their professional careers within the optical industry.
