Dr. Yung Answers Your Questions About Nearsightedness
What is Myopia? What is the progression? At what age does it begin and when does it stop progressing?
Myopia (or nearsightedness) is when there is a mismatch between the focusing power of the cornea and (the front of the eye) and the length of the eyeball itself. Ideally, the cornea focuses incoming light to a point directly onto the retina (back of the eye) which allows for a clear image to be formed inside the brain. In the case of myopia, the cornea focuses the light somewhere in front of the retina which then causes the image formed to be blurry. This mismatch between the length of the eye and the focusing power of the cornea is usually fixed with glasses that have a minus power. The minus power indicates a lens which counteracts the power of the cornea and moves the focal point of the light back onto the retina. The larger the mismatch, the greater the power of minus lens that needs to be prescribed.
Myopia can have progression rates that vary from person to person. The progression is most often due to the eye growing longer at a faster rate than the cornea can reduce its power. Myopia can begin at any age though it is very rare in infants and more common in school aged children. It can also stop progressing at any age but in general it tends to stop progressing in the late teens to early twenties.
