Astigmatism Treatment At Vision Source Castle Hills
Almost everyone is familiar with nearsightedness and farsightedness, but not everyone knows about the third common type of visual acuity problem, astigmatism. Like the other two visual problems, astigmatism affects your clear vision at a certain distance, but it's more of a challenge to correct the problem. At Vision Source Castle Hills, our San Antonio eye doctor offers multiple solutions for astigmatism, for patients from children to seniors.
San Antonio Optometrist Explains Astigmatism
Astigmatism is caused by the eyeball becoming misshapen. Our San Antonio optometrist, Dr. Raul Trevino, explains that the eye becomes shaped more like a football than a perfectly round sphere. When light comes into the eye, it bends more strongly in some directions, and less so in others. This means you can only easily focus on objects that are certain distances away, and the amount of focus changes from one distance to the other. Unlike with nearsightedness and farsightedness, you'll need multiple prescriptions to correct your vision completely. Most astigmatism patients are born with the condition, but it can also happen due to an accident, a disease, or some types of surgery.
There is only one basic symptom of astigmatism: blurred vision. You may actually think you've become nearsighted, but a comprehensive eye examination is the only way to be sure.
Our Eye Doctor in San Antonio is Treating Astigmatism
The only way to treat astigmatism is to change the way your eyes see the outside world. For most patients, this means eyeglasses or contact lenses. If you choose eyeglasses, we'll create a pair of multi-focal lenses that account for all the different ways your eyes try to focus.
Those who choose contact lenses will almost always get a better field of vision. With the lenses directly on your eye, you won't suffer from blanks in your peripheral vision. Patients with the most severe cases can be helped by using rigid gas permeable lenses, which can give the clearest vision of all the contact lens varieties.
If you're looking for a more permanent solution, refractive surgery can permanently change the shape of your cornea. Your eyes must be in perfect health, with no scars to your cornea, and you'll need to consult with our eye doctor to decide which of the many types of surgery is the right one for you.
The only way to tell if your blurry eyesight is actually astigmatism is by coming in for an eye examination. Give our office a call at (210) 344-1400 to schedule an appointment today.
