What is Astigmatism?

Astigmatism is a common condition that affects people of all ages. If you have astigmatism, it is because you have an irregularly-shaped cornea or curvature of the lens inside your eye that causes blurry or distorted vision¹.  But, don’t worry, you’re not alone, astigmatism is actually very common. A recent publication by Graeme Young estimates that of 47% of people with some form of vision correction have significant astigmatism in at least one eye²!
 

How Does Astigmatism Affect Your Vision?

People with astigmatism often have trouble focusing on an object at a distance. This can be especially apparent when looking at things like numbers or letters, regardless of how far away they are.

Can I Wear Contact Lenses if I have Astigmatism?

Of course! Advancements in manufacturing technology and contact Lens design have dramatically improved over the past decade and there are multiple brands available. In fact, some contact brands like ACUVUE® OASYS® provide coverage for 96% of patient prescriptions, including astigmatism. There are multiple other brands that offer broad prescription coverage as well. Some contact lens manufacturers even offer UV-blocking technology in their astigmatism lenses. Ask your doctor what contact lens brand is right for you.

 

What are the differences in Astigmatism Contact Lenses?

Unlike regular contact lenses, astigmatism lenses should not rotate on your eye. So when your head moves, your lenses should not. If your contact lenses do rotate, you may experience blurry vision. Think about when you look down at your phone to text – if your lens moves too much, your vision can blur. Astigmatism contact lenses are designed to minimize contact lens movement due to effects of gravity and eye movement.
