Ophthalmic Optics II

At the end of OPT 306 (Ophthalmic Optics II) course, the students should be able to: 1. explain the different type of bifocal and multifocal lenses and their functions; 2. identify different types of coats, tints / dyes and mechanism of absorptive lenses; 3. explain the reason behind dispensing tinted, photochromic and protective lenses; 4. explain and differentiate high power lenses such as lenticular lens, high index lenses and many others; 5. discuss about the manufacturing of lenses both glass and plastic lenses; 6. identify different parts of ophthalmic frames, and concept of impact resistance; 7. obtain interpupillary distance measurements; 8. discuss the concept of lens and frame specifications; 9. explain facial measurements of presbyopic patient for proper lens fitting; and 10. describe the principle of vertex power in the optics of both contact and spectacle lenses.

Bifocal and multifocal lenses; base curve and near ADD; types and specifications of bifocal segments; trifocals; absorptive lenses; coats; tints and dyes; optics of contact lenses and low vision devices; impact resistance.
