Astigmatism FAQ


Astigmatism FAQ’s Answered By Our Carmel Optometrist at RevolutionEYES

Blurry vision at only specific distances, unexplained headaches, and eye fatigue aren’t as uncommon as one might think. In fact, our Carmel optometrist at RevolutionEYES in Indiana provides treatment and care for quite a few patients with these symptoms, and most of them have been diagnosed with a vision condition called astigmatism. Here are answers to some of the most frequently asked questions about astigmatism.

What is Astigmatism?

When light coming into the eye cannot be fully focused, a vision condition called astigmatism results. However, this vision problem is not a disease, and it is not typically progressive with proper corrective care. Uncorrected, it can cause blurry vision at all distances and throw off one’s ability to properly perceive refractive angles, and astigmatism is commonly accompanied by farsightedness, nearsightedness or both.

What Causes Astigmatism?

Those with this vision concern have corneas (the front of the eye) that are more oval in shape than round. Unfortunately, this shape prohibits light entering the eye from properly focusing on the retina (the back of the eye). The causes of this irregular shaping can be the result of genetics, pressure from the eyelids, keratoconus or some type of scarring or trauma.

Are there Symptoms and Signs of Astigmatism Beyond Blurry Vision?

The level of blurriness and vision distortion will depend on the level of astigmatism present. However, even those with mild forms of astigmatism are more likely to experience eye strain, eye fatigue, and headaches. Those receiving proper care and treatment from our Carmel optometrist are likely to experience fewer symptoms overall.

How is Astigmatism Diagnosed by my Carmel, Indiana Eye Doctor?

There are additional evaluations we perform after a regular vision exam service to help identify and ‘map’ astigmatism issues. Using a combination of corneal topography, keratometry, and retinoscopy, we can see how your particular case corresponds to radiating demarcation lines we call meridians. Our Carmel optometrist gets two essential measurements through these exams: a sphere number and a cylinder number that is representative of your particular corneal aberration.

What Treatments are Available for Astigmatism?

While eyeglasses were the only option available for quite a while, there are now several treatment possibilities for those with astigmatism. Today, there are excellent contact lenses for astigmatism including hydrogel options to keep eyes moist, toric lenses and gas permeable options that offer effective vision treatment. Those who prefer not to wear corrective lenses during the day can opt for orthokeratology, which allows users to wear contacts at night that reshape the cornea so they can have a clear vision during the day. However, those seeking a permanent option should discuss LASIK surgery with our eye doctor.
