Astigmatism Explained

Corrective lenses for astigmatism are called Doric lenses that have greater light bending properties. The correct lens for vision correction for astigmatism is decided after the eye doctor ophthalmologists or the optometrist, one who is an expert on testing the vision and prescribing eyeglasses to correct eye defects; performing a couple of diagnostic tests on the patient.

If the degree of astigmatism is light and no other problems of refraction, such as nearsightedness or farsightedness, corrective lenses may not be needed. If the degree of astigmatism is great enough to cause eyestrain, headache, or distortion of vision, prescription lenses will be needed for clear and comfortable vision. The other option to treat astigmatism is refractive surgery.

The curvature of the cornea is corrected with the help of laser eye surgery. However in order to perform the surgery, the eye doctor has to make sure that the patient does not have any problem in the retina, scar on the corneal surface or any other eye problem. The removal of corneal tissue allows better refraction of light and hence formation of a clear image.
