Astigmatism Doesn’t Rule Out Contact Lenses

Are you aware that there are contact lenses especially for people with astigmatism? A normal cornea is spherical, but the cornea of an eye with astigmatism is more oval-shaped, sort of like a football. This affects the way light enters the eye, and as a result, vision is out of focus.

Contact lenses designed to fix astigmatism, known as toric contact lenses, are constructed from the same material as regular spherical contact lenses. What separates these from common lenses is the design. Think of them as the bifocals of contact lenses; they have a power to fix your distance vision issues and another for your astigmatism. They are designed with curvatures at different angles. Because of their multiple powers, toric lenses must remain in place on your eye. This is not the case with normal lenses, which can move around on your eye without affecting your sight. A smart feature of astigmatism-correcting lenses is the fact that they're heavier at the bottom, which helps them stay in place when you blink.

Toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you are used to colored or multifocal contact lenses, there are toric lenses for you. Hard contact lenses, also called rigid gas permeable lenses, have a stronger shape which helps them stay in place, but usually, they're a little less agreeable to wear than soft lenses. There's a contact lens which is just right for you.

Toric contact lens fittings may often require more time than the regular lens fittings you might be used to, because of the relative complexity of the lens. It might seem like a bit of effort, but it's well worth the end result; getting treated, glasses-free. Getting the best product for you will only improve your vision, and consequently, your everyday life.
