II. Catalog Description
This course will cover computations and theories concerning basic lens formulas; preparation of prescription lab orders; operation of the lensometer/vertometer and the neutralization process; and operation of lens fabrication equipment including the automatic lens edger, blocking, marking and hand bevel edgers. Fabrication of eyeglass prescriptions involving spherical and compound lenses in plastic and metal frames; interpretation, computation and creation of prismatic prescriptions through decentration will also be addressed. The course will include lecture time on appropriate optical principles. (Students will be required to supply their own tools.)
If the student is registered with the State Board as an apprentice, Ophthalmic Materials I must be successfully completed to be eligible for the State Board Qualifying Technician Exam.
III. Statement of Course Need:
This is a required course for both the Ophthalmic Science degree and apprentice students. This course is also required by the Commission on Opticianry Accreditation (COA).
