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.

Dear Valued Patient,

At The Eye Studio, the health and safety of our patients and employees is our top concern. Based on the recommendation from the Alberta College of Optometrists, our practice has decided to close for six weeks.

During this time, we will be available for emergency care, and we will arrange for patients to come pick up their glasses or contact lenses. You can leave a voicemail or email us here.

If you need to order contact lenses, please call our office for assistance.

While we hope to return to normal business hours starting May, please refer back to our website for updates as this situation is developing.

The Eye Studio Team
