Do I need special contacts for astigmatism?
Astigmatism is a common vision condition that affects millions of people worldwide. It occurs when the cornea or lens of the eye is irregularly shaped, causing light to focus unevenly on the retina. While glasses are a common solution for correcting astigmatism, many individuals wonder if they need special contacts for this condition. In this article, we will explore the different types of contact lenses available for astigmatism and help you determine whether you need special contacts or not.
Understanding Astigmatism
Astigmatism can cause blurred vision, eye strain, and headaches. It is often accompanied by nearsightedness (myopia) or farsightedness (hyperopia). To correct astigmatism, the goal is to create a smooth, even surface on the cornea or lens to ensure that light focuses properly on the retina.
Types of Contact Lenses for Astigmatism
1. Toric Contact Lenses: These are the most common type of contact lenses for astigmatism. Toric lenses have different powers in different meridians, allowing them to correct the irregular shape of the cornea. They come in various designs, including spherical, aspheric, and multifocal.
2. Gas-Permeable Contact Lenses: These lenses are made of a rigid material that allows oxygen to pass through to the cornea. They are often recommended for individuals with severe astigmatism or for those who have difficulty wearing soft contact lenses.
3. Hybrid Contact Lenses: Hybrid lenses combine the benefits of both soft and rigid gas-permeable lenses. They have a soft skirt that conforms to the eye, while the central part is made of a rigid material to correct astigmatism.
4. Scleral Contact Lenses: These large-diameter lenses rest on the white part of the eye (sclera) and vault over the cornea. They are suitable for individuals with severe astigmatism, keratoconus, or other corneal irregularities.
When Do You Need Special Contacts for Astigmatism?
If you have been diagnosed with astigmatism and are considering contact lenses, here are some factors to consider:
1. Severity of Astigmatism: If you have mild astigmatism, you may be able to wear regular soft contact lenses. However, for moderate to severe astigmatism, toric lenses or other specialized lenses may be necessary.
2. Lifestyle: If you lead an active lifestyle, you may prefer gas-permeable or hybrid lenses, as they are more durable and less likely to fall out. Scleral lenses are also a good option for those with an active lifestyle or who engage in sports.
3. Comfort: Some individuals may find that toric lenses provide better comfort and vision correction compared to regular soft contact lenses.
4. Eye Health: Specialized lenses may be necessary if you have other eye conditions, such as keratoconus or severe dry eye.
Conclusion
In conclusion, whether you need special contacts for astigmatism depends on the severity of your condition, your lifestyle, and your eye health. Consult with an eye care professional to determine the best type of contact lenses for you. With the right lenses, you can enjoy clear, comfortable vision and continue with your daily activities without the hassle of glasses.
