Course description
This course provides students with the laboratory skills required for quality control of lenses, and also with the ability to layout and prepare lenses for edging. Students will learn how to maintain the equipment and tools associated with the edging and finishing laboratory. This course provides students with the skills needed to insert and mount lenses into various frame materials and designs.

Learning outcomes

Upon completion of this course, successful students will be able to:

  • spot check lenses for surface quality
  • verify the power of a single vision lens with the lensometer
  • mark the optical centre and major reference point of a single vision lens
  • calculate horizontal and vertical lens decentration
  • calculate lens blank size requirements
  • use equipment for dispensing eyeglasses including the lensometer, pupilometer, distometer, lens clock ruler and thickness callipers
  • perform the process of lens edging
  • perform lens insertion and mounting with various frame designs and materials
  • verify completed eyewear
  • define ophthalmic terms pertaining to frame materials, designs, fitting and adjustments
  • perform frame fitting and adjustments
  • incorporate cultural safety and humility in opticianry practices
  • discuss the history and ongoing effects of colonization on the Indigenous Peoples of Canada, including disparities of power in patient-provider relationships
  • identify situations where informed consent may be problematic and take appropriate steps to ensure patient understanding
  • adhere to infection prevention and control measures established by jurisdiction and national regulatory bodies
  • recognize significant signs and symptoms in relation to the patient's eyes to identify the need for referral
