  • Astigmatism

    Astigmatism is a vision condition that causes blurred vision due to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye.

    The specific cause of astigmatism is unknown. Astigmatism occurs due to the irregular shape of the cornea or the lens inside the eye. The cornea and lens are primarily responsible for properly focusing light entering your eyes allowing you to see things clearly. Sometimes astigmatism may develop following an eye injury or eye surgery. Astigmatism can be diagnosed through a comprehensive eye examination.

  • Astigmatism

    Testing for astigmatism measures how the eyes focus light and determines the power of any optical lenses needed to compensate for reduced vision. Persons with astigmatism have several options available to regain clear vision. The Extrapolated Prevalence of Astigmatism in France is 9,996,652 .Prevalance Rate for Astigmatism is approx 1 in 6 or 16.54% or 45 million people.
