Astigmatism is an eye condition wherein the corner of your eye has an irregular shape, causing your vision to be blurry at any distance. While minor astigmatism may not cause any issues with your vision, significant astigmatism needs to be corrected. For this reason, your eye doctor may suggest using toric contact lenses.
Today, Nova Vision Center gives an overview of toric contact lenses and explains why it’s used by people with astigmatism.
What Are Toric Contact Lenses?
Toric lenses are contact lenses that are shaped in a unique way. Standard contact lenses have a spherical surface, but tori lenses are shaped more like a donut. The shape of toric contact lenses creates different refractive powers on vertical and horizontal orientations. As you move around the lens, the refractive strength increases or decreases moderately.
If you have astigmatism, your cornea is curved, which means the refraction of your eye will differ between the vertical and horizontal planes. Therefore, you may have blurry vision. In some cases, you might notice vertical lines are tilting. Since toric contact lenses have different refractive powers on the vertical and horizontal orientations, they provide relief for people with astigmatism.
What Should You Consider When Choosing Toric Contact Lenses?
Like any other contact lenses, toric contacts must be prescribed by an optometrist who will perform a thorough eye exam to select the ideal lenses for your condition. Toric contact lenses have a very specific orientation, featuring a middle axis that keeps your line of vision clear. If they don’t fit your eyes well, you will be unable to see clearly.
Additionally, toric contacts come in both soft and rigid gas permeable (RGP), or hard, lenses. While RGP lenses are better at staying put, they involve a longer initial adjustment time. They are also drier and more delicate. Soft toric contacts, on the other hand, are more comfortable. However, they need extra care to stay put properly.
