Bifocal Lenses

What are Bifocals?

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.

Dear TSO Patients,

We will continue taking precautions at our office.

-Our staff will be wearing masks. We also ask that any patient coming to our office wear a mask.

-Patients will call our office when they arrive to check in. Patients will be asked to stay in their cars until we are ready to start the exam.

-Patients’ temperature will be taken upon entry, and they will be asked to sanitize their hands.

-To reduce the amount of people in the office, only the patient is allowed into the exam room unless the patient is a minor or need additional assistance.

-Exam rooms, credit card terminals, counter tops, etc. will be wiped down between patients.

-Patients should call when they come for pickup of glasses and contact lens orders, we will deliver to them curbside.

-Frames that have been handled in the optical will be placed into a tray, and sanitized before they are returned to the frame board.

-Our office will continue to do curbside dispensing for eyeglasses and contact lenses.

Thank you for your support.

Drs. Hassett, Noorali, and Your TSO Staff
