Millions of children will start school this year with a vision problem that may inhibit their ability to learn and ultimately affect the rest of their lives. As parents send their children back to school, one of the most important things they can do to help ensure their child’s ability to learn is to take them for an eye exam. The American Optometric Association (AOA) recommends comprehensive eye exams especially for children entering preschool and kindergarten. An eye exam will help correct common vision problems, such as nearsightedness and farsightedness as well as more serious conditions such as amblyopia, commonly known as lazy eye. Amblyopia affects about 5 percent of children nationwide. The condition is preventable if detected within the first few years of life. The lack of early eye care has allowed amblyopia to escape detection, and it remains the leading cause of blindness in Americans under 40.
