What to Know About Wearing Contacts with Astigmatism
Astigmatism occurs when the shape of the cornea or lens of the eye is curved or misshapen. As a result, light does not enter the eye correctly. It is a common condition, in fact many people are born with astigmatism. It can even be considered hereditary. And while it sounds potentially worrisome, it is not even considered a disease.
Astigmatism is a common eye problem that makes vision feel blurry or distorted. Fortunately, it is possible to wear special toric prescription contact lenses designed for people with astigmatism. It is important to get a proper fitting from an eye care professional to ensure the contact lenses are comfortable and provide improved vision. As is the practice with any type of vision issues, contact lenses have to fit properly regardless if you happen to have astigmatism or not.
What is Astigmatism?
Astigmatism affects the front part of the eye (the cornea), which is the lens that bends so that light can pass through the eye. The shape of the cornea is supposed to be rounded like a perfectly shaped ball. But when astigmatism occurs, the eye shape is uneven and curved. Near and far vision can also be affected when someone has astigmatism.
There are two types of astigmatism: regular, also called corneal, and then irregular. The type of astigmatism is based on the structure that is misshapen.
Regular astigmatism or corneal - the principal meridians (steepest or flattest curves) are perpendicular to one another.
Irregular astigmatism - the principal meridians are not perpendicular or the surface of the cornea appears bumpy.
Can I Wear Contact Lenses with Astigmatism?
Most astigmatism falls into the mild category, so yes, contacts for astigmatism is an option. But the contact lenses must be a special type: toric contact lenses. Toric contact lenses are a type of contact lens designed to correct astigmatism, which is an irregular curvature of the cornea or lens of the eye that causes blurred or distorted vision. Toric lenses have different powers in different meridians of the lens to help the light focus properly on the retina, providing clearer vision.
It is important to wear these specific lenses for astigmatism, because traditional contacts will not help correct vision. In fact, wearing regular contacts with astigmatism can further damage the eyes. This is why it’s critical to see an eye doctor or vision specialist who can properly diagnose astigmatism and prescribe the correct contact lenses.
Contacts for Astigmatism
Toric Soft Contact Lens
Toric contact lenses are specifically made to address the condition of astigmatism. They have different powers in different meridians of the lens to help compensate for the irregular shape of the cornea and provide clearer vision. The effectiveness of toric lenses are usually higher than that of traditional contacts, because of the way they are made to statically lay on cornea, providing a better field of vision. Toric lenses are soft which increase ease of wear. Check out the best soft contacts made by Acuvue Oasys for astigmatism from our partners at ContactsCart.
Also the best contacts for astigmatism can offer the flexibility of daily contact lenses use such as the DAILIES AquaComfort Plus Toric 90pk.
The consistency and dependability of a monthly toric contact lens order ensures your best contact lenses are at the ready to keep vision sharp.
Bausch + Lomb Ultra monthly disposable soft contact lenses are another contact lens option for those with astigmatism.
Toric Hard Lens/Rigid Gas Permeable Contact Lenses
Toric contact lenses are a firmer or hard type of material that provides greater stability while inside of the eye. Toric lenses are more durable and do not bend or fold. These contacts are also called Rigid Gas Permeable (RGP) lenses. Hard lenses usually provide a clearer sight. However, keep in mind that these lenses require more cleaning and disinfection. Toric lenses are the best for long term because of their rigidity, they will last a lot longer, saving money over time.
Toric Hybrid Contact Lenses
Toric hybrid lenses provide just what their name suggests – they are a blend of both soft and hard contacts. These lenses are more flexible in the center with a rigid ring on the outside of the contact. This provides the best of both options providing comfort of a soft lens and stronger vision correction that rigid gas permeable contacts are known for.
Caring for Toric Contact Lenses
Toric contact lens care is an important part of maintaining the health and longevity of contact lenses. To ensure cleaning of lenses is done correctly, use a contact lens cleaner specifically designed for the type of contact lenses you have.
Place the toric contact lens in the palm of the hand. Start by gently rubbing the le
