Astigmatism
What is astigmatism?
In astigmatism, the front surface of the eye, or cornea, has
a non-spherical shape. The oval curve of the cornea in astigmatism
is similar to the shape e of an egg, rather than spherical like
a golf ball.
What are the effects of astigmatism?
People with astigmatism tend to have blurred or distorted vision
when viewing detail at far distances or close up. It is also common
to get headaches or eyestrain with uncorrected astigmatism.
How can astigmatism be detected?
Your optometrist will perform a test known as refraction to determine
the amount of astigmatism in your prescription.
Can astigmatism be corrected?
Absolutely. Both glasses
and contact lenses
can be prescribed to clear up the blur created by astigmatism.
Toric contact lenses are specially designed for people with astigmatism
and provide sharper vision than regular contacts. Refractive
surgery is also an option to correct astigmatism.
