Learn More About Astigmatism
Astigmatism is an uneven or irregular curvature of the cornea or lens of the eye which can blur vision.
Most people have some degree of astigmatism. However, squinting, eyestrain, headaches, fatigue, and difficulty driving at night are all signs that the problem needs to be corrected.
Only a comprehensive eye exam can detect astigmatism and indicate the necessary prescription.
Your Northern New England area eye doctor has advanced diagnostic equipment to determine the shape of your cornea and then prescribe the right solution. These tests may include:
A distance chart which measures visual acuity (commonly identified as a fraction such as 20/20).
A keratometer, an instrument that determines the precise curvature of the cornea and provides guidance on the shape of the contact lens.
Corneal topography, an advanced technique that provides even more detail on the shape of the cornea.
Refraction test will show how your eyes refract or focus light. This can be done manually with a phoropter, a multi-lens tool, or with an automated instrument.
