One focal point to provide visual acuity for distance, reading or intermediate vision (i.e. computer)
Often referred to as a "lined bifocal", these have two focal points for distance and reading. The bifocal portions come in varied widths, from 28mm, to 35mm to the full width of the lens
Often referred to as "no-line bifocal", these lenses are progressive multifocals, providing increasing power for intermediate and near viewing as the wearer drops their line of sight down the lens. Progressives provide a more youthful appearance and more function.
Ophthalmic lens production recently entered a new age - the digital age.Sophisticated software programs and equipment create more complex lens designs producing prescriptions with pinpoint accuracy. This translate into lenses that correct higher order aberrations (coma, quadrefoil) yielding a higher level of visual performance unattainable with the traditional process.
