Laboratory in Contact Lenses and Optical Technologies I

Course Code: DOPT 2113
Faculty: Science & Technology
Department: Dispensing Optician
Credits: 6.0
Semester: 15
Learning Format: Lecture, Lab
Typically Offered: Fall
course overview

This course introduces students to the lab skills for quality control of contact lens materials, solutions, and their ocular applications. It also provides students with the ability to calibrate, maintain and implement the usage of the equipment and tools associated within the contact lens dispensary. Students will gain further experience with the use of automated refraction equipment. Students will practice the skills required to assimilate information collected on contact lens materials, solutions, as well as techniques for ocular application and refractive error correction.
