Bifocal Lenses

Sometimes our vision fails us at two or even three distinct distances, especially as we age. Bifocal lenses—lenses with two distinct viewing areas—have traditionally been a reliable solution to such a dilemma. (A lens with three distinct viewing areas is called a trifocal.)

By distinct, we mean there are noticeable lines separating the two different fields of vision within a bifocal lens surface. A slight adjustment to the angle of the head allows wearers to choose which lens area to look through based on the distance of the object they’re trying to see.

A farsighted person who also has trouble reading may be prescribed a pair of bifocal reading glasses, for example. The upper section of the lens would correct difficulties seeing objects at distance, and the lower section would assist in reading. (Bifocal glasses date back to the days of Benjamin Franklin!)

While wearers quickly adjust to the line separating the multiple vision fields, it is a noticeable distraction within the lens itself. This line can be eliminated using a newer lens technology called progressive lenses.

Progressive lenses incorporate two, three, or more fields of vision within a single lens without noticeable lens lines. Bifocal, trifocal and progressive lenses are all considered “multi-focal” lenses—lenses that provide correction to multiple vision problems.

Our Restart

Following the governor’s latest guidance, we will be here for preventative and urgent eye care beginning Monday, May 4th by appointment only. We are committed to quality eye care, and we have put in place the following precautions to keep all of us safe:

  • Staff will wear masks and we ask each patient to wear a mask.
  • If possible, please complete the online history form @ Drarbow.com prior to your examination time.
  • Companions will be asked to wait outside unless needed for mobility or cognition issues.
  • As with staff, patients will have a temperature check and be asked screening questions before they are taken back to the exam room.
  • We have established a schedule to facilitate a “no wait” policy, and we will make every effort to seat the patient upon arrival.
  • We will limit the number of patients in the dispensary. Each frame will be disinfected if handled.
  • UV-C air filters and sanitizers have been placed throughout the office.
  • Enhanced and more frequent cleaning of surfaces and touchpoints has been implemented.
