Myopia (short-sightedness) is a common condition where distance objects appear blurry, and near objects may be visible depending on the amount of myopia. The eye is like a camera and to get a clear image, light entering the eye must focus on the macula. In a myopic eye, this light focuses in front of the macula. This causes blurring and the image to be unclear. If not corrected, this can cause headaches, increased eye strain and may impair ability to perform daily activities such as driving.
The conventional treatment for this is using spectacles. The correct lenses bend the light to move the point of focus back onto the macula. Spectacle correction is effective in many cases and provides clear vision. Other options include contact lenses, laser vision correction or cataract surgery.
