What Are The Causes Of Astigmatism?

astigmatism isn’t too severe

Astigmatism occurs when the front surface of the eye, the cornea, is slightly curved. Luckily, astigmatism isn’t too severe and can generally be corrected quite easily by the use of toric Contact Lenses. The illustration to the right depicts the main differences between an average eye with astigmatism and one that have astigmatism. Notice the eye has an irregular shape, because it is slightly curved.

As you can see, astigmatism means that your cornea isn’t perfectly spherical. When looking at an object outside at night, you will notice that it looks slightly fuzzy. This is because the cornea is slightly irregular. Because of this, light cannot properly come through and focus on the retina. Your vision will be slightly distorted or blurry.

One of the most common causes for people to have astigmatism comes from their age

Many younger people will have blurred vision as they get older, due to their corneas being unable to fully heal. In fact, some individuals will need glasses as adults because the damage to their eyes cannot be reversed. Some common symptoms associated with astigmatism include headaches, nausea, and eye strain. Often times, these symptoms are mistaken for other eye problems, which can cause further confusion.

If you’re experiencing headaches or eye strain with your current eye condition, you should talk to your optometrist about having your eyes examined. He or she will be able to perform a test called a refractive examination to determine if astigmatism might be a problem. The exam will show if there are gaps or lines in your vision caused by your near and far sightedness. If there is a problem, your optometrist may recommend that you wear eyeglasses or contact lenses. However, he or she may recommend just using a toric contacts to correct your vision.

astigmatism often needs to be corrected with glasses

If you’re looking to buy prescription glasses, you’ll find that there are many different types of glasses available. However, your optometrist can only help you identify which type of glasses will suit your needs best. For example, regular astigmatism can often be corrected with regular glasses. However, if you have irregular astigmatism, you will need to wear toric contacts to correct your vision.

Now that you understand what causes astigmatism, you should also understand what eye surgery options are available. Correcting astigmatism does not always require the use of corrective eye surgery. For example, if you wear glasses every day, you shouldn’t have to avoid wearing them unless you want to. If you have nearsightedness, farsightedness or astigmatism, you can purchase glasses that will adjust to these conditions. In addition, you may be able to purchase specially designed glasses for astigmatism if your optometrist can’t help you get the correct glasses. Although astigmatism often needs to be corrected with glasses, you don’t have to put up with it if you have options.
