Astigmatism is a very common condition that causes blurred vision. In the normal eye, light rays come into the eye and hits the cornea and gets refracted into a single focal point directly on the retina. However, an eye with astigmatism has multiple focal points. Typically, it can be easily treated by an experienced eye doctor in Greenville SC.
Astigmatism is the most common refractive error in the world. There are more people who have astigmatism than people who are near-sighted or far-sighted. It has to do with the shape of the eye. People with no astigmatism at all have a cornea that is perfectly round. They have a basketball shaped eye. The refractive power of the vertical meridian and the horizontal meridian of the cornea are the same. If you have astigmatism, you have two different curvatures to your cornea. (The cornea is the clear, front surface or the window that sits over the color part of your eye). When you have astigmatism, you have two different refractive surfaces. The refractive power of the vertical meridian is different from the refractive power on the horizontal meridian. On one side, you have a steep part to the eye and one the other side you have a flatter part to the eye. These two refractive surfaces that causes the light to focus on two different points behind the eye. Because of this, instead of having one power for your prescription glasses; you have two. Astigmatism can be treated with either glasses, contacts or laser surgery. There are a few ways that your eye doctor in Greenville SC like ours at Oneway Eyeglasses can treat astigmatism. Astigmatism can be easily treated with eyeglasses or toric contact lens. Toric contact lenses are contact lenses that are specifically designed to correct astigmatism. Toric contact lenses are a bit more expensive than average contacts. Laser surgery is another option. It can be performed to reshape the cornea and to make it a more spherical shape.
