Summary: Certain people require a special type of contact lens due to astigmatism known as toric contact lenses.
Toric contact lenses are ideal for patients that suffer from astigmatism, as they are designed to correct the refractive error that is caused by an irregularly shaped cornea. These contact lenses are available from a majority of the leading contact brands out there, so you have numerous options to choose from – and in both daily or monthly wearing patterns.
How Toric Contact Lenses Work
Toric contact lenses correct the vision issues that arise from the abnormal curvature of the cornea. Shaped like a ring rather than a standard spherical lens, these lenses create different horizontal and vertical refractive power that increase or decrease depending on the movement of the lens itself.
Patients that suffer from pronounced astigmatism who try to wear standard contact lenses will notice that they won’t sit comfortably on the eye, which will directly affect visual clarity and comfort. This is because the cornea is not a standard shape, so manufacturers need to use various methods to ensure the toric contact lenses sit flush on the eye.
It’s crucial to purchase contact lenses that fit comfortably and keeps your line of vision clear. A quick consultation with your eye doctor can confirm whether you need toric lenses or not.
What Type of Contact Lenses Are Right for You?
In order to find the right type of toric contact lens, you’ll need to take your wearing pattern preferences into account. You can purchase these through your optometrist or through an online retailer. Take note that if you are purchasing online, you will still need a valid prescription from an optometrist.
