Astigmatism can’t be eliminated with exercises or lifestyle changes, but it can be fully corrected with glasses, contact lenses, or surgery. The right option depends on how severe your astigmatism is, your age, and whether you want a permanent fix or are comfortable with daily correction. Most people with astigmatism have several effective paths to clear vision.
What Causes Astigmatism
A normal eye has a front surface (cornea) shaped like a basketball, with equal curvature in every direction. With astigmatism, the cornea is shaped more like a football, curving more steeply in one direction than the other. This uneven curvature bends light unevenly, so instead of focusing to a single sharp point on the retina, light lands in two different focal points. The result is blurry or distorted vision at all distances.
Less commonly, astigmatism comes from an irregularly shaped lens inside the eye rather than the cornea. Both types produce similar symptoms and are measured in diopters. Mild astigmatism (under 1 diopter) often causes no noticeable problems, while moderate to high astigmatism (2 diopters or more) typically needs correction.
Why Eye Exercises Don’t Work
Programs claiming to reduce astigmatism through eye exercises, vitamins, or visual training have no scientific support. The American Academy of Ophthalmology states plainly that there is no evidence any eye exercise program will reduce or eliminate the need for glasses, and that exercises are ineffective for astigmatism specifically. Astigmatism is a structural issue with the shape of your cornea or lens. No amount of muscle training can reshape those tissues.
Glasses and Contact Lenses
The simplest correction is a pair of glasses with a prescription that compensates for the uneven curvature. The lenses are ground with different powers along different angles, counteracting the distortion your cornea creates. This works well for any level of astigmatism and is the lowest-risk option.
Contact lenses designed for astigmatism are called toric lenses. They have a weighted or shaped design that keeps them oriented correctly on your eye so the correction lines up with the axis of your astigmatism. Soft toric lenses work for most people, though higher or irregular astigmatism sometimes requires rigid gas-permeable lenses, which create a smooth optical surface over the uneven cornea.
Orthokeratology: Temporary Reshaping
Orthokeratology (Ortho-K) uses rigid contact lenses worn overnight that gently reshape the cornea while you sleep. You remove them in the morning and see clearly throughout the day without glasses or contacts. It’s a good middle ground if you want freedom from daytime correction but aren’t ready for surgery.
Ortho-K works best for mild to moderate cases. Most fitting protocols require astigmatism of 2 diopters or less, and you need to wear the lenses for at least 7 hours each night. The effect is entirely temporary. If you stop wearing the lenses, your cornea returns to its original shape within days. This makes Ortho-K reversible but also means it’s a nightly commitment for as long as you want the correction.
LASIK Surgery
LASIK is the most well-known permanent correction for astigmatism. A surgeon creates a thin flap in the cornea, then uses a laser to reshape the tissue underneath, smoothing out the uneven curvature. The flap is repositioned and heals naturally. Most people notice dramatically clearer vision within 24 hours.
LASIK can correct up to 6 diopters of astigmatism, which covers the vast majority of cases. The average cost runs between $1,500 and $3,000 per eye, with bladeless (all-laser) procedures averaging around $2,100 per eye and more advanced wavefront-guided options closer to $2,500. The cost for astigmatism correction falls within the same range as standard LASIK.
One important reality: not everyone stays at perfect vision long-term. A 10-year follow-up study of LASIK patients with myopia and astigmatism found that about 36% of eyes needed a retreatment over that decade. Vision remained substantially better than before surgery, but there was slight regression from the initial correction. Setting realistic expectations matters. LASIK dramatically reduces dependence on glasses, but some people eventually need a thin prescription again or opt for a touch-up procedure.
PRK: An Alternative Laser Option
PRK uses the same laser reshaping technology as LASIK but skips the corneal flap. Instead, the surgeon removes the thin outer layer of the cornea entirely, reshapes the tissue, and lets the outer layer regenerate. This makes PRK a better choice if your corneas are too thin for LASIK or if you’re in a profession with high risk of eye trauma (the absence of a flap means there’s no flap to dislodge later).
The tradeoff is recovery time. While LASIK patients typically see well the next day, PRK recovery takes several days to a week before vision clears, and full stabilization can take a month or more. The final visual results are comparable.
SMILE: A Newer Approach
Small Incision Lenticule Extraction, or SMILE, is a newer laser procedure that has gained popularity over the past decade. Instead of creating a flap or removing the surface layer, the laser creates a small disc-shaped piece of tissue inside the cornea, which the surgeon removes through a tiny incision. This reshapes the cornea with less disruption to its surface.
A meta-analysis comparing SMILE and LASIK found that both provide effective, predictable results with generally equivalent outcomes for astigmatism correction. SMILE may have a slight edge in one area: LASIK has a greater probability of causing a type of post-surgical optical distortion called spherical aberration. The smaller incision in SMILE also preserves more of the cornea’s structural strength.
Implantable Lenses
For people with very high prescriptions or corneas unsuitable for laser surgery, implantable lenses offer another permanent option. These work like contact lenses placed inside the eye, in front of your natural lens.
The toric version of the Implantable Collamer Lens (ICL) can correct astigmatism up to 4 diopters while simultaneously correcting nearsightedness up to 20 diopters. Candidates are typically between 21 and 60 years old, need a stable prescription for at least a year, and must have healthy eyes without corneal disease. Unlike laser surgery, ICL is reversible because the lens can be removed if needed.
Toric Lenses During Cataract Surgery
If you’re having cataract surgery and also have astigmatism, a toric intraocular lens (IOL) can correct both problems in a single procedure. Since your natural lens is being replaced anyway, swapping in a toric version adds astigmatism correction at no additional surgical step.
Good candidates have regular (not irregular) astigmatism of 1 diopter or more, with consistent corneal measurements and a stable eye surface. People with irregular astigmatism from conditions like keratoconus or corneal scarring are generally not good candidates, as a toric lens could actually make their vision worse. Fewer than 5% of patients need further corrections after a toric IOL implantation. When residual astigmatism does occur, it’s most often because the lens was placed at a slightly imperfect angle or rotated slightly after surgery.
Choosing the Right Option
Your best path depends on several factors working together. Mild astigmatism under 1 diopter may not need any correction at all. For moderate astigmatism, glasses and toric contacts are the simplest starting point, and Ortho-K lenses offer daytime freedom without surgery. If you want a permanent solution, LASIK, PRK, and SMILE all handle astigmatism up to about 6 diopters with similar success rates. Very high astigmatism combined with significant nearsightedness may point toward an implantable lens.
Age plays a role too. Refractive surgeries like LASIK require a stable prescription, so most surgeons want you to be at least 18 to 21 with a prescription that hasn’t changed in a year. On the other end, people in their 50s or 60s developing cataracts can address both problems at once with a toric IOL. Budget is also a practical consideration: glasses and contacts have lower upfront costs but accumulate expense over years, while LASIK at roughly $2,000 to $3,000 per eye is a larger one-time investment that typically pays for itself within a few years of not buying lenses and frames.
