Can People with Astigmatism Wear Contacts?**
A common question among individuals with astigmatism is whether they can wear contact lenses. The simple answer is yes, with the right type of contact lenses, people with astigmatism can definitely wear contacts. But it's important to understand that contact lenses are not a cure for astigmatism, but a tool to correct the vision problems caused by astigmatism.
What is Astigmatism?
Astigmatism is a refractive error that occurs when the shape of the cornea, the eye's front window, is irregularly curved or unevenly shaped. This condition can cause blurred or distorted vision, as light rays entering the eye are not focused properly on the retina, which is the light-sensitive layer at the back of the eye. While most people with astigmatism can wear contact lenses, the degree of correction required for each individual can vary.
Why Use Contacts Instead of Glasses?
There are a few main reasons why people opt for contact lenses over glasses. Firstly, contact lenses can provide a more natural look and feel by covering the entire cornea, which reduces the risk of rubbing against the eyes and creating lines or creases in the skin under the frames. Additionally, contact lenses can offer a wider field of view, which is particularly beneficial for activities such as driving or sports. Contact lenses can also be more comfortable for some people, as they are less intrusive and do not obstruct the face.
Types of Contact Lenses for Astigmatism
People with astigmatism can wear two main types of contact lenses: toric contact lenses and aspheric lenses.
Toric Contact Lenses
Toric contact lenses are specifically designed to correct astigmatism by having different powers in different meridians of the lens. This allows the lens to focus light evenly on the retina, providing clear vision regardless of the position of the gaze. Toric lenses are available in both soft contact lens materials and rigid gas-permeable (RGP) materials. Daily disposable toric lenses are a popular option for people who prefer a fresh pair of lenses each day.
Aspheric Contact Lenses
Aspheric lenses are designed to minimize optical aberrations present in the eye, which can improve the quality of vision for people with astigmatism. Aspheric lenses do not necessarily correct astigmatism but can be a good option for people with mild astigmatism. Contact lenses can be made from a variety of materials, including hydrogels and silicones.
Caring for Contact Lenses with Astigmatism
Proper care and maintenance of contact lenses is essential for maintaining good eye health and preventing complications. Some tips for caring for contact lenses with astigmatism include:
- Replacesolution regularly: Replace your contact lens solution as recommended by your eye care professional to maintain the health of your lenses.
- Cleanthe lenses: Use a contact lens cleaning solution specifically designed for your type of contact lenses. Gently rub the lenses with a few drops of cleaning solution between your fingers and the lens, then rinse and air dry.
- Store lenses properly: Always store your contact lenses in their storage case, which should be cleaned and disinfected regularly.
- Avoid contact with makeup and facial creams: Remove your contact lenses before applying makeup or facial creams to prevent the transfer of germs.
- Take off lenses before water activities: Remove your contact lenses before engaging in activities such as swimming or showering to prevent water ingress and potential damage to the lenses.
- No sleeping in lenses: Don't sleep in your contact lenses, as this can lead to increased risk of irritation, dryness, and infections.
By following these tips, you can maintain healthy contact lenses and enjoy clear vision with minimal complications. If you have questions about contact lenses or your vision, consult with your eye care professional for personalized advice.
