Astigmatism is a type of refractive error. (Refractive errors are eye problems that affect your vision). If you have astigmatism it means your cornea is misshapen.
The cornea is your eye’s outermost lens. It focuses the light that enters your eye.
A normal cornea is spherical. With astigmatism, the cornea has an irregular curve. This changes how light passes through to your retina.
Astigmatism can cause:
The causes of astigmatism are unknown. Many believe that genetics play a large role.
It is common for astigmatism to occur with nearsightedness (myopia) or farsightedness (hyperopia).

Glasses, contacts, and surgery are the most common ways to correct astigmatism.
Many people prefer to wear contact lenses to correct their astigmatism. They are affordable, convenient, and provide excellent visual acuity.
You can use soft or hard (rigid gas permeable, or RGP) contacts to correct astigmatism. Most people opt for soft lenses since they are comfortable and easy to use.
You’ll need special lenses, called “toric” lenses, if you have astigmatism. Toric contact lenses have two “powers.” One corrects your astigmatism and the other corrects your near or farsightedness. They also have a weight on the bottom to make sure they stay in place and don’t rotate. (Normal lenses have one power and your vision is not affected if they rotate).
There are many different types of contacts for astigmatism. Here are the best for each category:
Dry eyes are a common problem for people with astigmatism. That’s why 1-Day Acuvue Moist are one of the most popular contact lenses on the market. They feature LACREON® technology with an embedded wetting agent. This gives your eyes a cushion of moisture all day. Plus the added convenience of never needing solution or contact cases.
Many contact wearers prefer daily disposable lenses for their convenience. You don’t need a contact case or solution. Instead you throw each pair out at the end of the day.
They also are better for your eye health. Your eyes contain calcium, proteins, and lipids. These build up on reusable lenses and increase your chance of infection. Disposable contacts are always sterile, greatly reducing your chances of infection.
Again, 1-Day Acuvue Moist Astigmatism lenses top the list of this category.
Dailies brand lenses by Alcon are another popular choice. Their AquaComfort Plus Toric lenses provide crisp and clear vision. A moisturizing agent is released with every blink so your eyes stay moist all day.
Biotrue ONEday lenses are another top choice. They reduce halos and glare, so if that is an issue for you with other lenses, these may be the best choice for you. They also have one of the highest water contents available.
Weekly contact lenses can be worn for one to two weeks. Once again, Acuvue tops the list in this category. Acuvue Oasys lenses come with HYDRACLEAR® PLUS technology. This helps to stabilize tear film, resulting in less dryness.
Monthly contacts only need to be replaced every 30 days. Biofinity Toric Monthly lenses are made of silicone hydrogel. This is a very breathable material that lets oxygen pass through efficiently.
Bonus: Some patients can use Biofinity Toric Monthly lenses for up to 7 days/6 nights of continuous wear. Not all patients can achieve the maximum wear time. Speak with your eye care practitioner for more information.
*Biofinity Toric XR Monthly are also available for people with astigmatism and high prescriptions.
If you have presbyopia (farsightedness) and astigmatism you’ll need multifocal lenses. Bausch + Lomb Ultra Multifocal lenses are the top choice for this category. They are a monthly lens. They use a 3-Zone Progressive design. This provides vision correction up close, far away, and in between.
AIR OPTIX for Astigmatism contacts can only be worn for extended wear (24 hours including while you sleep) if directed by your eye doctor. Be sure to get a professional lens fitting and ask your eye care professional if extended wear contacts are right for you.
*Important Safety Information: Not all patients can wear the lenses for extended wear. Approximately 80% of patients are able to wear the contacts during the day and at night. Always follow the eye care professional’s recommended lens wear, care and replacement schedule. Overnight wear of contact lenses has been shown to increase the risk of certain serious contact lens–related complications. See more AIR OPTIX Safety Information.
If AIR OPTIX NIGHT & DAY AQUA contacts don’t work for you, Biofinity Toric Monthly may be a better option. However, they can only be worn for up to 7 days/6 nights.
Before ordering any contacts online, be sure to get an eye exam and contact lens fitting. Speak with a professional eye doctor or optometrist to find out which contact lens design is best for you.
1800 Contacts has a huge selection of contact lenses and award-winning 24/7 customer service.
