More than 70 million people in North America (about one in four) are myopic (nearsighted). The term “nearsighted” means that you can see objects that are closer to you more clearly than distant objects. The more myopic you are the more blurred distant objects appear. If you have a highly myopic prescription, you are likely to have very thick edges to your glasses.

Myopia (Nearsightedness) occurs when your eye is too long in relation to the curvature of your cornea. This causes light rays entering the eye to focus in front of the retina, producing a blurred image.

Below are the categories of severity for myopia:

  • Mild Myopia < -3.00 diopters
  • Moderate Myopia -3.00 to -6.00 diopters
  • Severe Myopia -6.00 to -9.00 diopters
  • Extreme Myopia > -9.00 diopters
