Contact Lenses for Astigmatism
Astigmatism is a disorder of the eye, in which the cornea (the clear dome in front of the eyeball) is irregularly shaped. Normally, the cornea equally refracts light that comes from all directions. In astigmatism that light is refracted unequally, causing the patient to see all images in a blurred manner. Depending on the shape of the cornea, the blurring can be anywhere from mild to severe.
Contact lenses can be used to correct the irregular shape of the cornea, resulting in better vision. There are several different types of contact lenses used to correct astigmatism. These include; soft contact lenses, rigid gas permeable lenses, toric lenses, or toric rigid gas permeable lenses. Which lens is best depends largely on the severity of the astigmatism.
SOFT CONTACT LENSES
RIGID GAS PERMEABLE LENSES
TORIC RIGID GAS PERMEABLE LENSES
If you have a known astigmatism, ask your doctor about contacts on your next visit.
