Toric contact lenses for astigmatism
The normal, healthy cornea is a spherical shape with only one symmetrical curve. Accordingly, there is only one focal point for light to pass through and reflect onto your retina. In sum, that’s how vision works and how you see clearly. However, when you have astigmatism, the cornea has an elongated shape that creates a second curve. As a result, light does not focus properly on your retina. The result is blurry and distorted vision for both near and distance. Our Greensboro eye doctor can diagnose astigmatism during your regular eye exam.
What is the treatment for astigmatism?
Astigmatism, a relatively common condition, is typically corrected effectively by prescription eyewear. Our optometrist will issue you a precise vision prescription that states the lens powers you need for each eye, as well as the cylinder you need to correct your astigmatism. Depending on your preference, we can provide a prescription for glasses or specialized toric contact lenses.
How can contact lenses correct astigmatism?
Contact lenses look like a neat and perfectly circular disc, which may make you question how this symmetrical shape can fit comfortably on eyes with astigmatism. In general, your question is 100% understandable – and standard contacts cannot correct astigmatism. Instead, a specialized type of contact lenses, called toric contacts, must be worn to correct astigmatism. We stock a full range of toric lenses in our Greensboro contact lenses collection!
How are toric contact lenses different from standard contacts?
Toric contact lenses have an oblong shape. The most popular types are soft toric lenses, made from hydrogel or silicone hydrogel. These specialty contacts for astigmatism are available in various wearing schedules, including daily wear, daily disposables, and extended wear.
While less common, toric contacts also come in hard gas permeable (GP) versions, which have a longer adjustment period – but can be just as comfortable as soft lenses once you adapt to them. Also, some people find them easier to care for in the long term.
If you have astigmatism, look closely at your prescription for Greensboro contact lenses. You’ll see it has a number to correct your nearsightedness or farsightedness, alongside a number for the cylinder to correct your astigmatism. When you wear your toric contacts, they must remain vertically aligned to give you sharp vision. They should move up and down only when you blink. In order to accomplish this, the contacts are specially weighted with thick and thin zones.
Is fitting toric contact lenses more difficult?
Yes, it is more complex to fit toric contact lenses. That’s why you need an expert eye doctor to perform your contact lenses eye exam and fitting. Our Greensboro optometrist is experienced and highly qualified to fit both hard and soft toric lenses precisely!
It can take a bit of trial and error to pinpoint the perfect toric contact lenses for your eyes. We will work with you patiently until your contacts give you comfortable, crisp vision. Also, toric lenses can be costlier than standard contacts, due to the customization required to craft them.
