Toric and Multifocal Lenses: What Are the Differences?

Toric and Multifocal Lenses: What Are the Differences?

Suffering from astigmatism? In need of correction for multiple distances? Toric and multifocal lenses may be the answer. But what are the differences? Let’s find out together.

What are toric lenses?

Toric lenses correct for astigmatism. With astigmatism, eyes resemble a rugby football rather than a soccer ball. Astigmatism, in essence, means an abnormal curvature of the cornea or lens. Think of it like the eye being squished slightly. We know, not a pretty sight!

This being said, toric lenses still come from the same material as regular spherical lenses. In toric lenses, the lens carries particular optical power and focal length in two places perpendicular to one another. Toric lenses also have a thickness at the lens bottom to ensure the lens stays stable, even when moving around.

What are multifocal lenses?

Multifocal lenses correct for multiple distances—near, medium, and far—on a single lens surface, simultaneously. People with myopia, nearsightedness, and hyperopia, farsightedness, can benefit from multifocal lenses. This is especially true if reading close-up has become an issue. Playing trombone is only fun in the orchestra.

What are the differences?

The major differences between the two, toric and multifocal lenses, are toric lenses are monofocal in nature and used to correct for astigmatism. Monofocal lenses have a set range—close, medium, or far—and reading glasses may still be necessary if seeing close-up has become difficult.

Summary

Glasses are not for everyone. Contact lenses could be the solution to your vision problems. If you have astigmatism, then toric lenses are probably your best bet. Multifocal lenses will come in handy if your lifestyle demands optimal vision up-close and far away.
