Introduction to light theory included. With the prescription as the starting point, blanks are selected, computations made, layout determined, marking and blocking accomplished, and the final lens verified. Hand edging as the first skill in fabrication of eyeglasses is developed. First of three courses which develop skills and knowledge necessary for successful contact lens fitting. History of contact lenses and development of each material are considered, as well as indications and contraindications to contact lens wear.
Infection control is introduced.
Emphasis on instrumentation associated with contact lens fitting and diagnostic skills. Proficiency is developed in contact lens verification and evaluation of fit. Bifocal and progressive lens design and fitting emphasized. Law of refraction is presented. In addition to taking proper measurements necessary for making a pair of glasses optically correct, students become well-versed in tool use and basic frame adjusting.
