Can You Wear Contacts If You Have Astigmatism?
Yes, absolutely! Many people with astigmatism successfully wear contact lenses. In fact, contact lenses can often provide a clearer, more comfortable vision correction for astigmatism than eyeglasses. However, it's crucial to understand the different types of contact lenses available and to work closely with an eye care professional to find the best option for your specific needs.
What is Astigmatism?
Before we delve into contact lens options, let's briefly define astigmatism. Astigmatism is a common refractive error where the cornea (the clear front surface of your eye) is not perfectly spherical. This irregular shape causes light to focus unevenly on the retina, leading to blurry or distorted vision at all distances. Symptoms can include eye strain, headaches, and difficulty seeing at night.
What Types of Contact Lenses Correct Astigmatism?
Unlike spherical contact lenses which correct nearsightedness (myopia) and farsightedness (hyperopia), astigmatism requires specialized lenses. Here are the primary types:
-
Toric Contact Lenses: These are the most common type of contact lens used to correct astigmatism. They have a different curvature on different meridians of the lens, compensating for the irregular shape of the cornea. Toric lenses come in both soft and rigid gas permeable (RGP) materials.
-
Multifocal Toric Contact Lenses: For individuals with both astigmatism and presbyopia (age-related loss of near vision), multifocal toric lenses offer correction for both conditions. These lenses incorporate different zones to provide clear vision at various distances.
-
Rigid Gas Permeable (RGP) Lenses: RGP lenses, while less commonly chosen for astigmatism correction than soft toric lenses, offer exceptional clarity and oxygen permeability. They are particularly beneficial for individuals with high astigmatism or certain corneal conditions.
What are the Advantages of Contact Lenses for Astigmatism?
-
Sharper Vision: Many individuals find contact lenses provide clearer vision than eyeglasses, especially in peripheral vision.
-
Improved Cosmetic Appearance: Contact lenses offer a more natural look compared to eyeglasses, eliminating the frames and allowing for a wider field of vision.
-
Better Performance in Sports and Activities: Contact lenses stay in place during physical activity, unlike eyeglasses which can shift or fall off.
-
No Distortion at the Periphery: Unlike eyeglasses, which can distort vision at the edges of the lenses, contacts provide a more natural and consistent image across your entire visual field.
Are There Any Disadvantages of Contact Lenses for Astigmatism?
-
Higher Initial Cost: Toric contact lenses are generally more expensive than spherical lenses.
-
More Difficult to Handle: Toric lenses require more precise handling and placement due to their specific orientation.
-
Increased Risk of Complications: Improper care or wearing time can increase the risk of infections or other complications.
How Do I Get Started with Contact Lenses for Astigmatism?
The first and most important step is to schedule a comprehensive eye exam with an optometrist or ophthalmologist. They will assess your astigmatism, evaluate the health of your eyes, and determine the best type of contact lens for your specific needs. They will also provide you with instructions on proper lens care and handling.
What if I Experience Discomfort or Problems with My Contact Lenses?
If you experience any discomfort, blurry vision, redness, or any other problems with your contact lenses, it's vital to contact your eye care professional immediately. Do not attempt to self-treat.
Can I wear daily disposable toric contacts?
Yes, daily disposable toric contact lenses are available and offer convenience and hygiene benefits. Discarding the lenses daily eliminates the need for cleaning and reduces the risk of infection. However, the cost per year might be higher than reusable lenses.
By working closely with your eye doctor, you can find the perfect contact lenses to manage your astigmatism and enjoy clear, comfortable vision. Remember, proper care and regular checkups are crucial for maintaining eye health while wearing contact lenses.
