Astigmatism is a treatable imperfection in how your eyes curve that causes blurred distance and up close vision. It occurs when the front of your eye or lens has misaligned curves.
Typically, the curves in your eye form a round ball. For people suffering from astigmatism, the surface is egg-shaped and causes blurred vision.
There are three main types of astigmatism:
This occurs when light rays are brought to a focus in front of the retina.
Hyperopic astigmatism occurs when light rays are brought to a focus in the back of the retina.
This occurs when your vision is alternatingly nearsighted and farsighted.
The most common symptoms of astigmatism include the following:
The leading cause of astigmatism is a refractive error in the eye. This affects both the cornea — the clear front surface of the eye — and the lens — the clear structure inside the eye that changes shape for focus.
In a person with 20/20 vision, both of these elements are rounded. This ensures that the light is refracted correctly and focused on the retina and at the back of the eye. Astigmatism occurs when either the lens or cornea is shaped like an egg, improperly refracting light rays and causing a blurry image.
A physician may be able to tell at the time of birth if you have astigmatism, though its symptoms won’t be pronounced enough. You might also develop astigmatism after an eye injury, disease, or surgery.
For a long time, astigmatism could only be helped with hard lenses. The team at Optom-Eyes Vision Care Optometry is happy to offer patients soft corrective lenses (known as toric lenses) to correct your astigmatism. Your optometrist might also recommend LASIK surgery to permanently fix your astigmatism.
