Common Eye Conditions that may be noted in 6 year olds to early 20's include the following: Myopia(nearsightedness), Hyperopia (farsightedness), Astigmatism, Amblyopia(Lazy Eye), Eye Infections, Eye Trauma and Contact Lens related problems.
The most common vision problem in this age group is refractive in nature, meaning a need for glasses. I recommend annual eye exams for this age group because I think it is important to detect any vision problems early so that blurred vision does not cause a problem in school. In Manitoba at least a portion, if not all, of the eye exam fee is paid for by Manitoba Health for those 18 and under.
