Contact Lenses for Astigmatism: How Toric Lenses Work

Published · By Dr. Lu Eye Care · 5 min read · Contact lenses

Astigmatism is one of the most common reasons people are told contacts "won't work" for them. That advice is out of date. Today there are soft lenses, rigid lenses and specialty designs that correct astigmatism well. This guide explains how lenses for astigmatism work, what your options are, and what to expect from a fitting.

What astigmatism is

In an eye without astigmatism, the cornea (the clear front surface) is curved evenly in every direction, a bit like a basketball. With astigmatism, the cornea, or sometimes the lens inside the eye, is curved more steeply in one direction than the other, more like a football. Light focuses at two different points instead of one, so vision is blurred or slightly distorted at all distances. People with uncorrected astigmatism often notice eye strain, squinting, headaches or trouble with glare at night.

Astigmatism frequently occurs together with nearsightedness or farsightedness, and it can change slowly over the years.

Spotting astigmatism on your prescription

On an eyeglass prescription, astigmatism shows up in two columns: CYL (cylinder), which is the amount of astigmatism in diopters, and Axis, a number from 1 to 180 that describes its orientation. If the CYL box is blank or says "SPH" or "DS," you have little or no astigmatism in that eye. Our guide on how to read an eyeglass prescription explains each column.

Keep in mind that a glasses prescription cannot be converted directly into a contact lens order. A separate fitting is needed; see contact lens exam vs. regular eye exam.

How toric soft lenses work

Lenses designed for astigmatism are called toric lenses. Unlike a standard spherical lens, which has the same power all the way around, a toric lens has different powers in different directions to match the shape of your eye. That creates a challenge: the lens has to stay in the right orientation. If it rotates when you blink, the correction lines up in the wrong direction and vision blurs.

Manufacturers solve this with stabilization designs. Some lenses are slightly heavier or thicker at the bottom so they settle into place; others use thicker and thinner zones that interact with your eyelids during blinking to keep the lens aligned. Toric lenses also carry small marks, usually near the bottom edge, that let your eye doctor see whether the lens is sitting where it should.

Soft toric lenses come in daily disposable, two-week and monthly versions, and in a range of materials. Some brands also make toric multifocal lenses for people who have astigmatism and need help with near vision.

Other contact lens options for astigmatism

  • Rigid gas permeable (RGP) lenses. These firm, oxygen-permeable lenses keep their own shape on the eye, so the tear layer beneath them smooths out much of the astigmatism coming from the cornea. They often give very crisp vision but take some time to get used to.
  • Hybrid lenses. A rigid center surrounded by a soft skirt aims to combine the sharp optics of an RGP lens with the comfort of a soft lens.
  • Scleral lenses. These large rigid lenses vault over the cornea and rest on the white of the eye. They are often used for irregular astigmatism, such as from keratoconus or after corneal surgery.
  • Standard spherical lenses. With very low astigmatism, some people see well enough in a regular soft lens. Your eye doctor can tell you whether that is realistic for your eyes.

What a toric fitting involves

  1. Measurements. Your refraction and corneal measurements show how much astigmatism you have and where it comes from.
  2. Trial lens. A diagnostic lens is placed on the eye and allowed to settle for several minutes.
  3. Checking rotation. Using the slit lamp, the doctor looks at the lens markings to see whether the lens rotates and by how much.
  4. Compensation. If the lens consistently settles slightly rotated, the doctor adjusts the axis on your final lens to compensate, so the correction lines up correctly on your eye.
  5. Vision check and follow-up. Vision is tested with the lens in place, and a follow-up visit confirms the fit after some days of normal wear.

Because of these extra steps, a toric fitting can take longer than a standard fitting and sometimes needs more than one trial lens.

Tips for success with toric lenses

  • Give each new lens a moment to settle after insertion; a few blinks usually help.
  • Do not switch brands on your own. Different designs stabilize differently, and the axis compensation may change.
  • Tell your doctor if vision fluctuates when you blink or look to the side, which can mean the lens is rotating.
  • Keep your eyes comfortable. Dryness can make lenses move more, so mention any dryness at your visit.
  • Follow your replacement schedule and care routine; see our contact lens care tips.

Cost and availability

Toric lenses are more complex to manufacture, so they usually cost more than spherical lenses, and the fitting often carries a higher fee. Very high amounts of astigmatism may require custom-made lenses with longer ordering times. Contact lenses and fitting fees are generally eligible expenses for HSA and FSA funds; see using your HSA or FSA for eye care.

Glasses or contacts for astigmatism?

Both work, and many people use both. Glasses are simple, need no daily care and are easy to update. Contacts move with your eyes, so side vision is not interrupted by frames, and they are practical for sports. Some people with higher astigmatism find that rigid lenses give sharper vision than glasses, because the lens corrects the uneven corneal surface directly. If you choose contacts, keep a current pair of glasses as a backup for days your eyes need a break.

Whichever you choose, astigmatism can change over time, so keep up with yearly exams. Your eye doctor will check whether your correction still matches your eyes.

Bottom line

Astigmatism is not a barrier to contact lenses. Toric soft lenses work well for most people, and rigid, hybrid or scleral lenses are available for eyes that need something different. The key is a careful fitting by an eye doctor who checks how the lens behaves on your eye and adjusts it until your vision is clear and stable.
