Myopia, hyperopia, and astigmatism are common reasons children wear glasses. But what do these terms mean? What causes these conditions? When should you have your child’s eyes checked? Dr. Taressa G. Haney of Charlotte Eye Ear Nose & Throat Associates, P.A. joins us this month to answer these questions and more about your children’s eyesight.
What is myopia? How common is it in children?
Myopia or near-sightedness is when your vision without glasses is better at near than distance. Light rays from a distant object focus in front of the retina, resulting in a blurred image at distance. The prevalence of myopia increases with age and differs according to ethnicity.
What is farsightedness? How common is it in children?
Hyperopia or far-sightedness in children is normal. The majority of children are hyperopic, and this is a normal state which gives children excellent vision at both near and distance. Children are able to “focus” through the hyperopia to see well at both near and distance. We lose this ability as we age and eventually most adults over the age of 40 need reading glasses to see up close.
What is astigmatism? How common is it in children?
Astigmatism is when the light rays do not focus on a single point on the retina. Astigmatism is caused by variations in the curvature of the cornea and lens. Astigmatism can cause blurred vision at distance and near. Astigmatism can be present at any age. Read More →
