Can Contacts Fix Astigmatism?
Astigmatism is one of the most common refractive errors, affecting millions of people worldwide. Unlike nearsightedness (myopia) or farsightedness (hyperopia), astigmatism is caused by an irregularly shaped cornea or lens that leads to distorted vision. This condition can affect your ability to see objects clearly at any distance. For those living with astigmatism, vision correction is essential, and one of the questions often asked is: Can contacts fix astigmatism? The answer is yes, but with certain considerations and options that we will explore in this blog.
At Sunnyside Vision Center of Queens, NY, we provide a comprehensive range of solutions for astigmatism, including contact lenses tailored specifically for this condition. In this post, we’ll cover the basics of astigmatism, how contact lenses can correct it, and what to expect from the different types of contact lenses available.
What is Astigmatism?
Astigmatism occurs when the cornea or lens inside the eye has an irregular shape. A perfectly shaped cornea or lens is smooth and equally curved, similar to a basketball. This shape helps light to focus directly on the retina at the back of the eye, producing clear images. However, when you have astigmatism, the shape is more like a football or the back of a spoon. This irregular shape causes light to focus on multiple points instead of just one, leading to blurred or distorted vision.
Astigmatism can occur alongside myopia or hyperopia, making it essential to have a tailored vision correction plan. Individuals with astigmatism may experience symptoms such as headaches, eye strain, and difficulty seeing at night.
Can Contact Lenses Fix Astigmatism?
Yes, contact lenses can effectively correct astigmatism. Traditional contact lenses, designed for either nearsightedness or farsightedness, aren’t suitable for astigmatism because they cannot accommodate the irregular shape of the cornea or lens. However, toric lenses, which are specifically designed for astigmatism, are available and can provide clear, sharp vision.
How Toric Lenses Work
Toric lenses are unique because they have different powers in different meridians of the lens, compensating for the irregular shape of the cornea or lens. Traditional contact lenses are spherical, meaning they have the same curvature across the entire surface. Toric lenses, on the other hand, are shaped to allow for different focusing powers in vertical and horizontal planes. This design allows them to correct the light distortion caused by astigmatism.
Additionally, toric lenses have a specific orientation to ensure the correct prescription aligns with the appropriate part of the eye. Many toric lenses are weighted at the bottom, using gravity and blinking to maintain proper alignment.
Types of Contact Lenses for Astigmatism
Several types of contact lenses are available for astigmatism. At Sunnyside Vision Center of Queens, NY, we can help you choose the best option based on your specific vision needs and lifestyle. The primary types of lenses include:
- Soft Toric Lenses Soft toric lenses are the most popular choice for individuals with astigmatism because they offer comfort and ease of use. These lenses are made from soft, flexible materials that allow oxygen to reach the eye, which is essential for long-term eye health. Soft toric lenses come in both daily disposables and extended wear varieties, allowing for flexibility based on your preferences.
- Rigid Gas Permeable (RGP) Lenses RGP lenses are a less common option but can be highly effective in correcting moderate to severe astigmatism. These lenses are made from rigid materials that retain their shape on the eye, providing more precise vision correction. Because of their firmness, they can counteract the irregularities in the cornea more effectively than soft lenses. However, they may take some time to adjust to and are typically not as comfortable as soft lenses initially.
- Hybrid Contact Lenses Hybrid lenses combine the best of both worlds. They have a rigid gas-permeable center with a soft outer ring, offering the sharp vision of RGP lenses with the comfort of soft lenses. Hybrid lenses can be an excellent option for those with high levels of astigmatism who find RGP lenses uncomfortable.
- Scleral Lenses Scleral lenses are larger, covering the entire cornea and resting on the white part of the eye (the sclera). These lenses are primarily used for individuals with irregular corneas, such as those with keratoconus, but they can also be beneficial for astigmatism. Scleral lenses create a smooth surface over the cornea, offering clear, stable vision. Additionally, these lenses provide a moisture barrier, making them a good option for those who also suffer from dry eyes.
Benefits of Contact Lenses for Astigmatism
Wearing contact lenses to correct astigmatism offers several benefits:
- Clear Vision: Unlike glasses, which can distort peripheral vision, contact lenses provide a more natural field of view. Toric lenses are designed to correct the irregular curvature of the cornea, allowing you to see clearly at all distances.
- Comfort: Today’s contact lenses, especially soft toric lenses, are designed with comfort in mind. Materials such as silicone hydrogel allow for extended wear and maximum oxygen permeability, reducing the risk of dry eyes and irritation.
- Aesthetic Appeal: Many people prefer contact lenses over glasses because they offer a more natural look and don’t interfere with daily activities such as sports or wearing sunglasses.
- Customization: There are various types of toric lenses available, meaning your eye doctor can customize your contacts based on your unique prescription and lifestyle.
Common Concerns and Misconceptions
Some patients with astigmatism worry that contact lenses may not be as effective as glasses, or they believe contact lenses are uncomfortable. At Sunnyside Vision Center of Queens, NY, we emphasize that modern contact lenses are designed with advanced technology, making them more comfortable, effective, and easier to use than ever before. Here are a few common misconceptions:
- “Contacts don’t work for astigmatism”: This is no longer true. With the variety of options available, contact lenses can work very well for astigmatism, providing sharp and clear vision.
- “Toric lenses are uncomfortable”: While rigid lenses may require an adjustment period, most people find soft toric lenses very comfortable after a short period. Hybrid lenses are also available for those who need the precision of RGP lenses with the comfort of soft lenses.
- “Toric lenses are expensive”: While toric lenses are often more expensive than regular lenses due to their specialized design, the cost difference is often minimal, especially when you consider the convenience and benefits they provide. Many insurance plans cover astigmatism correction lenses, and we offer various payment options at Sunnyside Vision Center.
When to See an Optometrist
If you suspect you have astigmatism, it’s essential to see an eye care professional for a comprehensive eye exam. An optometrist can diagnose astigmatism using a variety of tests, such as corneal topography or wavefront analysis, and determine the severity of your condition.
At Sunnyside Vision Center of Queens, NY, we provide thorough eye exams to diagnose conditions such as astigmatism, cataracts, glaucoma, and dry eyes. Our team of experienced Queens optometrists can prescribe the correct contact lenses and ensure they fit comfortably. With personalized care and advanced diagnostic tools, we help our patients achieve optimal vision and comfort.
Cataract Evaluation and Other Considerations
It’s also important to note that astigmatism can be linked to other eye conditions, such as cataracts. If you are over the age of 40 or have noticed changes in your vision, an eye exam can help determine whether astigmatism, cataracts, or another condition is impacting your vision. Our cataract evaluations at Sunnyside Vision Center include a full assessment to ensure your vision is being cared for in the best way possible.
