Single Vision – lenses used for simple prescriptions when a patient still has full range of focus, or targeted for a specific focus such as reading or computer work.
Bifocal – Allow clear vision at two distinct distances, such as distance and reading. A line seperates the two parts of the lens. Otherwise known as “lined bifocals” or “Flat Tops.”
Trifocal – Allow clear vision at three distinct distances, such as distance, intermediate (computer or dashboard distance), and reading. A line seperates the three parts of the lens.
Progressive – These lenses have a smooth transition from distance to near allowing clear vision at any distance. There is no line making the lens appear as if it were single vision. Otherwise known as “no lines.”
Occupational – Custom lenses designed for specific visual requirements.
