Multifocal Eyeglass Lenses

Multifocal lenses technically refer to any lens that provides more than one zone of corrective power and would therefore include bifocal, trifocal and progressive lenses. Multifocals are designed for the many individuals over 40 who struggle with presbyopia – the age-related near vision loss that requires us to use eyeglasses for reading and focusing on objects in our near vision. The multiple lens powers enable you to correct for near and distance vision with one pair of glasses.

Bifocal Lenses

Bifocal lenses are divided into two powers, one for distance vision and the second for near vision. Bifocals are created in a variety of designs with different sized and shaped viewing segments for near and far vision. While bifocals provide good distance and near vision, they are lacking in corrective power for intermediate areas, which is what has led to the development of trifocal and progressive lenses.

Trifocal Lenses

Trifocal lenses provide an additional lens power zone for intermediate vision (which is typically about an arm’s length away).

Some people are bothered by the visible lines where the lenses are divided in bifocal and trifocal lenses. In addition to aesthetics (the lines have become a sign of presbyopia which many associate with growing old), the harsh divisions in the zones can cause a distortion in the object you are viewing (an image jump) when you switch your gaze from one power to the next.

Progressive Addition Lenses (PALs)

Progressive lenses were designed to eliminate the “image jump” that results from the distinct zones in bifocal and trifocal lens design. By providing a smooth progression of many lens powers across the lens, PALs allow for clear vision near, far and every distance in between. Further, similar to natural vision, they just require a slight movement of the eye, rather than the whole head, for you to see through different lens powers. The smooth transition also eliminates the visible lines present on the other lenses which many view as tell-tale signs of age-related vision difficulties.

 

Every day optometrists take pride in helping our patients see clearly and preventing blindness. But today we need your help.

For over 30 years, the Ontario government has refused to formally negotiate with optometrists.

In 1989, the Ontario government paid $39.15 for an eye exam.

In 2021, 32 years later, they pay an average of $44.65.

This amount does not come close to covering the cost (including rent, staff, utilities, equipment, taxes and supplies) to provide an eye exam.

This is not sustainable and yet the Ontario government continues to ignore your care.

They have left optometrists with no choice. If they do not prioritize eye care, as of September 1, 2021, access to eye care for millions of Ontarians will end.
