Contact Lenses TORIC: now in color

The term "toric contact lenses" usually is used to describe specially designed soft contact lenses that correct astigmatism. Most toric contacts for astigmatism are indeed soft lenses — made either of a conventional hydrogel material or a highly breathable silicone hydrogel. But there are toric contact lenses made of rigid gas permeable (GP) contact lens materials, too.

Toric soft contact lenses for astigmatism differ from regular ("spherical") soft contacts that correct only myopia or hyperopia in two important ways:

  1. Toric lenses have different powers in different meridians of the lens to correct the varying amount of nearsightedness or farsightedness in different meridians of the eye that characterizes astigmatism.
  2. Toric lenses have a design feature that enables the lens to rotate to the proper orientation on the cornea so the power meridians of the lens align with the appropriate meridians of the eye for clear vision.

Different colored toric lenses

Because every eye with astigmatism is unique, it can take more than one pair of soft toric contact lenses to find the brand and design that provides the best fit, comfort and visual acuity. Also, fitting toric contact lenses for astigmatism takes more expertise than fitting regular soft lenses. For these reasons, getting fitted with toric contact lenses typically costs more than a regular contact lens exam and fitting.

Also, because they have a more complex design, the cost of replacement toric contact lenses is higher than the cost of regular (spherical) soft contacts. The difference in cost will depend on the lens design, lens material, and the optical retailer you purchase them from.

 

There also are color contact lenses with toric designs that correct astigmatism while enhancing or changing your eye color, and toric bifocal contact lenses that correct both astigmatism and presbyopia. There even are toric silicone hydrogel lenses designed for up to 30 days of overnight wear.

 

If you have astigmatism and are interested in wearing contact lenses, visit an eye doctor who specializes in fitting contact lenses for astigmatism. During a comprehensive eye exam and contact lens consultation, your doctor can advise you whether you are a good candidate for contact lens wear and which astigmatism-correcting contact lenses are best suited for your specific needs.
