Dealing with astigmatism can make you feel like your vision options are limited, but there is the good news: you can wear contacts with astigmatism.
That being said, contact lenses are not a one-size-fits-all solution. That’s why you’ll need to have a contact lens exam and fitting to ensure you’re wearing lenses that fit your eyes and correct your astigmatism.
Understanding Astigmatism & Its Effects on Vision
Astigmatism is a common refractive error caused by an irregularly shaped cornea or lens. Instead of a round, soccer-ball-like shape, astigmatic eyes may resemble more of a rugby ball.
This irregular shape prevents light from focusing evenly on the retina, resulting in blurred or distorted vision. Astigmatism can occur on its own or in conjunction with other refractive errors, such as nearsightedness or farsightedness.
Symptoms of astigmatism can include:
- Blurry or distorted vision at all distances
- Eye strain or discomfort
- Headaches, especially after reading or using screens
- Difficulty seeing at night
If any of these sound familiar and you’re ready for a glasses-free vision solution, contact lenses might be just what you need.
How Contacts Correct Astigmatism
Unlike regular contacts, which are designed for spherical corrections (nearsightedness or farsightedness), contact lenses for astigmatism have a unique design. This is because the irregular shape of an astigmatic cornea requires correction for more than one plane of vision.
Types of Contact Lenses for Astigmatism
There isn’t a one-size-fits-all approach when it comes to contacts for astigmatism. You have several options depending on the severity of the refractive error.
Toric Contact Lenses
Toric lenses are the most commonly prescribed contacts for astigmatism. Made from soft materials, they offer comfort and are available as daily, bi-weekly, or monthly options. They’re a fantastic starting point for anyone new to contact lenses.
Toric lenses are specially designed to correct the irregular curvature of the cornea or lens that causes astigmatism. What sets these lenses apart from regular, spherical ones is their unique shape, which has different powers in specific meridians of the lens to better align with your eye’s needs.
These lenses also feature a design that prevents rotation, ensuring precise and consistent vision. While they may require some practice to insert and align correctly, the payoff is sharp, reliable vision tailored for astigmatism.
Benefits of toric lenses include:
- Comfortable for prolonged wear
- Wide availability in different prescriptions
- Suitable for various activity levels
Rigid Gas Permeable (RGP) Lenses
Sometimes referred to as “rigid” lenses, RGP lenses are smaller and made from firmer materials. These lenses don’t mold to the cornea. Instead, they sit on the surface of the eye and correct astigmatism by creating a smooth refractive surface on top of the irregularly shaped cornea.
Benefits of RGP lenses:
- Provide sharp vision
- Durable and long-lasting
- Can correct more severe or high astigmatism levels
Scleral Lenses
Scleral lenses are a unique type of RGP lens that is larger in diameter and rests on the white part of the eye (the sclera) instead of the cornea. They create a vault over the cornea, leaving space filled with a saline solution to keep the eye hydrated and comfortable.
These lenses are often recommended for people with irregular corneas, dry eye syndrome, or other complex eye conditions.
Benefits of scleral lenses:
- Comfortable for people with sensitive or dry eyes.
- An excellent option for correcting irregular corneal shapes.
- Provide stable, clear vision due to their firm structure and larger size.
- Can enhance comfort and vision for people with conditions like keratoconus or post-surgical corneas.
Factors to Consider When Choosing Contacts for Astigmatism
When selecting contact lenses, here are some things to think about:
- Comfort: Depending on how sensitive your eyes are, you may prefer soft toric lenses over firmer RGP options. Scleral lenses are also great for balancing comfort and sharp vision.
- Visual clarity: Soft toric lenses are generally sufficient for most people, but if you have high astigmatism or require sharper correction, RGP or scleral lenses may be a better option.
- Lifestyle: Daily disposables are perfect for convenience and low maintenance, while monthly lenses are more cost-effective if you’re okay with regular cleaning.
- Budget: While toric lenses tend to be slightly more expensive than regular lenses, investing in the right type for your needs will lead to improved vision and comfort over time.
- Professional fit: Always ensure your contacts are fitted by a professional to maintain eye health and minimize risks such as discomfort or infection.
Tips for Comfortable Contact Lens Wear with Astigmatism
Adapting to contact lenses may take a bit of practice, but these tips can provide a smooth transition:
- Give it time: It might take a few days or weeks for your eyes to fully adapt to the unique alignment of toric lenses or how RGP and scleral lenses rest on your eye.
- Keep them clean: Always follow your eye care provider’s cleaning and storage instructions to keep your lenses sterile and avoid irritation.
- Moisturize your eyes: If you experience dryness, consider using rewetting drops or switching to lenses with high moisture content.
- Avoid overwearing: Follow the wear schedule recommended by your optometrist to protect your eye health and avoid fatigue.
Clear Vision Awaits with the Right Contact Lenses
Astigmatism doesn’t have to hold you back from switching to contacts. Whether you choose toric, RGP, or scleral lenses, there’s an option for everyone. With the correct type of lenses and professional support, you’ll enjoy clear, comfortable vision while saying goodbye to the restrictions of glasses.
