Your lens and cornea’s smooth surfaces and symmetric curves help in the equal distribution of light. These features also ensure accurate focusing of the received light rays on the retina. Irregularities of their form, however, may result in an imperfect light-bending process leading to refractive errors, such as astigmatism. For more information about astigmatism, ask your trusted eye care provider.
While the exact cause behind these optical/refractive irregularities remains unknown, heredity does play a large role in the development of an astigmatism. If any of your family members have this refractive error, you are more likely to also have issues. This condition may also occur because of external issues, including eye injury or surgery and can change over time.
According to your expert optometrist, there are two major types of astigmatism. The corneal type refers to astigmatism caused by an unevenly surfaced cornea, (the clear front surface lens of your eye) impairing its image focusing and light-bending into the eye. The lenticular kind, on the other hand, occurs when the natural ocular lenses inside your eyes are formed irregularly, distorting the normal light focusing process inside your eyes.
You may experience blurry vision, whether you’re looking at close or distant objects. Most of the time, lower degrees of astigmatism do not cause significant eyesight problems. That said, when the refractive error becomes moderate to severe, you may have a hard time finishing your daily tasks. You may also experience headaches, nausea, and eye fatigue. When this happens, we advise seeing your eye care specialist immediately.
Our Suggested Remedies
Wearing eyeglasses or contact lenses is an effective way to correct astigmatism. We may prescribe special astigmatic lenses for your eyewear or for your contact lenses. These lenses are specially crafted to correct the varying amounts of your astigmatic prescription at each point in your cornea and lens. We may also suggest undergoing LASIK or other refractive surgeries as a solution.
