All About Astigmatism
- Posted on: Aug 15 2020
Astigmatism is a common eye condition that causes blurred vision. This blurred vision is caused by the cornea (clear front cover of the eye) is irregularly shaped or the curvature of the lens inside the eye. The irregularly shaped cornea or lens then prevents light from focusing properly on the retina, making vision blurry at any distance. This blurred vision can lead to discomfort and headaches.
Astigmatism usually occurs with other vision conditions like myopia (nearsightedness) and hyperopia (farsightedness). These vision conditions together are referred to as refractive errors because they affect how the eyes bend or “refract” light.
There are many things that can cause astigmatism. But, it’s hereditary and is usually present from birth. It can decrease or increase over time. A comprehensive eye exam from an optometrist will include testing for astigmatism to determine if you have it or not. From there, you can decide how to approach treatment.
People with astigmatism have myriad options to enjoy clear vision, including:
- The most common option people with astigmatism choose to correct their vision is eyeglasses. These eyeglasses contain a cylindrical lens prescription that compensates for astigmatism.
- Contact lenses. Some people prefer contact lenses over eyeglasses. Contact lenses still help to provide the wearer with a clearer vision and a wider field of view. Keep in mind that standard soft lenses may not be effective in correcting astigmatism though. You will also have to be diligent about cleaning and maintaining your lenses.
- Laser and other refractive surgery procedures. LASIK or PRK (photorefractive keratectomy) can also be used to reshape your corneas to correct your vision. PRK works by removing tissue from the superficial and inner layers of the cornea while LASIK removes tissue from the inner layer of the cornea only. To determine which course of action would be best for your situation, you’ll have to schedule a consultation with a specialist.
