If you have astigmatism, you may have heard in the past that contact lenses were not an option for you. However, advances in contact lens technology now make it possible for most people with astigmatism to wear contacts safely and comfortably.
Today, toric and other specialty contact lenses are specifically designed to accurately and comfortably correct astigmatism. With proper fitting and good care, most people with astigmatism can successfully wear contact lenses. Many people find that their vision with contacts feels clearer and more natural than with glasses.
In this guide, you will learn how contact lenses for astigmatism work, the different types available, how they are fitted, the possible risks and costs, and what you should know before deciding to try contact lenses.
What Is Astigmatism?
Astigmatism is a common type of refractive error. It occurs when the cornea, which is the clear front surface of your eye, is not evenly curved.
Normally, the cornea is round like a basketball. In astigmatism, the cornea is more football-shaped. This uneven shape causes light to focus at several points in the eye rather than at a single sharp point on the retina.
As a result, your vision may appear in the following ways:
- Blurry at both distances and near
- Stretched or shadowed
- More sensitive to glare, especially at night
- Distorted in certain directions
Astigmatism often occurs together with other vision problems, such as:
- Nearsightedness (myopia)
- Farsightedness (hyperopia)
The amount and direction (axis) of your astigmatism will determine what type of vision correction is best for you.
Can You Wear Contact Lenses With Astigmatism?
In most cases, the answer is yes.
Modern contact lenses for astigmatism, called toric lenses, are specifically designed to correct the uneven curvature of the cornea. Many people with astigmatism achieve stable, clear vision with these lenses, often similar to what they experience with glasses.
However, the best type of contact lens for you will depend on several factors, including:
- The degree of astigmatism
- Corneal shape
- Tear film quality
- Lifestyle needs
It is important to have a proper contact lens fitting exam to ensure the best results.
How Do Toric Contact Lenses Work?
Toric contact lenses differ from regular, or spherical, contact lenses.
Toric lenses have several special features, including:
- Two different optical powers
- A specific axis alignment
- Stabilization zones that help prevent the lens from rotating in your eye
Because astigmatism affects how light enters your eye in different directions, toric lenses must stay in the correct position on your eye. If the lens rotates, your vision may become blurry until the lens moves back into place.
Modern contact lenses use special stabilization designs, such as prism ballast or dynamic stabilization, to help keep the lenses properly aligned on your eye throughout the day.
When toric lenses are fitted correctly, they can:
- Refocus the light onto the retina.
- Reduce distortion
- Improve visual stability
Types of Contact Lenses for Astigmatism
Astigmatism can vary from person to person. The best contact lens for you will depend on your prescription strength and personal preferences.
Soft Toric Contact Lenses
Soft toric contact lenses are the most commonly prescribed type of lens for astigmatism.
Best for:
- Mild to moderate astigmatism
- Patients seeking comfort and convenience
Available as:
- Daily disposables
- Biweekly lenses
- Monthly lenses
These lenses usually feel similar to standard soft contact lenses, and most people adapt to them quickly.
Rigid Gas Permeable (RGP) Lenses
Rigid gas permeable (RGP) lenses keep their shape on the eye, rather than conforming to the shape of the cornea like soft lenses do.
Best for:
- Moderate to high astigmatism
- Sharper visual demands
- Irregular corneas
RGP lenses often provide sharper vision than soft lenses, but they may require a short adaptation period as your eyes get used to them.
Hybrid Contact Lenses
Hybrid lenses combine:
- A rigid center (for clarity)
- A soft outer skirt (for comfort)
Hybrid lenses may be a good option for people who want the clear vision of RGP lenses but also want the comfort of soft lenses.
Orthokeratology (Ortho-K)
Orthokeratology, or Ortho-K, lenses are worn overnight while you sleep. These lenses gently reshape the cornea to correct vision temporarily.
In the morning, you remove the lenses and can see clearly during the day without needing glasses or contact lenses.
Best for:
- Active lifestyles
- Patients are avoiding daytime lens wear.
- Some cases of mild astigmatism
Ortho-K lenses are not suitable for all prescriptions, so your eye doctor will determine if they are right for you.
Contact Lenses vs Glasses for Astigmatism
Many people prefer contact lenses for astigmatism because they offer several advantages, such as:
- Provide a wider field of vision.
- Reduce peripheral distortion
- Do not fog or slide
- Allow you to wear sunglasses more easily.
However, glasses may be a better choice for some people, especially those who:
- Dry eye sufferers
- Occasional wear
- Prefer a lower-maintenance option.
Both contact lenses and glasses can effectively correct astigmatism. The best choice depends on your needs and preferences.
What Happens During a Contact Lens Fitting?
Fitting toric contact lenses for astigmatism is a more detailed process than fitting regular contact lenses.
Your eye doctor will:
- Measure corneal curvature
- Determine astigmatism power and axis.
- Evaluate tear film stability.
- Assess overall corneal health.
Your eye doctor will then place trial lenses on your eyes to check for the following:
- Rotation stability
- Visual clarity
- Comfort
Your doctor may need to make small adjustments in the lens power or axis to achieve the best vision and comfort.
A follow-up visit is important to ensure your lenses remain properly aligned and your cornea stays healthy.
Skipping follow-up visits can increase your risk of complications.
Possible Risks and Complications
Contact lenses for astigmatism are generally safe when they are worn and cared for properly.
Common temporary issues include:
- Dryness
- Mild irritation
- Temporary blurry vision if the lens rotates
- Redness related to contact lens wear.
More serious complications, such as corneal infection (microbial keratitis), are uncommon but can occur.
The risk of complications increases with the following:
- Overnight wear without approval.
- Poor hygiene
- Water exposure
- Overwear
Most complications can be prevented with proper care and regular check-ups with your eye doctor.
Safe Wear and Care Guidelines
Because contact lenses rest directly on the surface of your eye, good hygiene is very important.
Always:
- Wash and dry your hands before handling lenses.
- Use a fresh disinfecting solution.
- Replace lenses on schedule.
- Replace your contact lens case every three months.
Never:
- Rinse your lenses with tap water.
- Share lenses
- Sleep in non-approved lenses
If you experience pain, redness, sensitivity to light, or any discharge from your eyes, remove your contact lenses right away and contact your eye doctor.
How Much Do Toric Contact Lenses Cost?
Toric contact lenses usually cost more than standard soft lenses because they have a more specialized design.
Cost depends on:
- Brand
- Replacement schedule
- Lens material
- Specialty customization
Daily disposable lenses usually cost more per year than monthly lenses. RGP or hybrid lenses may have a higher initial cost, but they often last longer.
Many vision insurance plans include a contact lens allowance.
Ask your eye care provider for an estimate based on your prescription and lens choice.
FAQ
How long does it take to adjust to toric lenses?
Most people get used to toric contact lenses within a few days, but it can take up to two weeks to feel completely comfortable.
Can I wear contacts if I have high astigmatism?
Yes, you can wear contact lenses if you have high astigmatism. Rigid gas permeable (RGP) or specialty toric lenses may give better stability for higher prescriptions.
Are contact lenses safe long-term?
When contact lenses are properly prescribed, fitted, and cared for, long-term use is safe for most people.
Is there an age limit?
There is no strict age limit for wearing contact lenses. Whether they are right for you depends on your eye health and your ability to care for the lenses.
Final Thoughts
Having astigmatism does not mean you have to wear only glasses.
With modern toric lenses, most people with astigmatism can get clear, stable, and comfortable vision by wearing contact lenses.
The key to success with contact lenses for astigmatism is:
- Professional fitting
- Proper hygiene
- Regular monitoring
If you are thinking about contact lenses for astigmatism, schedule a comprehensive eye exam. Your eye care professional can help you find the safest and most effective option for your eyes and your lifestyle.
