Magic eyes


For normal three dimensional vision both eyes has to point directly to the object you want to see. Depending on the distance to the object the foreground and background will be out of focus. Similar to portrait photography where the face is in sharp focus but the background is soft.

About 10% of school age children have problems coordinating their eyes. Also known as eye teaming. Reading requires the eyes to point to the same spot on the printed page as well as the ability to maintain that coordination as the eyes scan across the page. The eyes of children with Eye coordinationcoordination problems have their eyes converge at a point beyond the page. In some cases the eyes even have different focal length. When this condition remain undiscovered the child has to fight with his or her eyes to get them to focus on the page. This lead to eyestrain, difficulties concentrating and staying on task. Some of these children are misdiagnosed as ADD since some of the symptoms are similar.

Eye coordination problems can also be a factor in children diagnosed as dyslexic. When children attempt to make their eyes move across a printed line in a book. Sometimes one eye lose the coordination and either move ahead or move back and letter or two.This may be one of the reasons the child reverse letters or words. Eye coordination is often the actual cause of symptoms that can be confused with ADD and Dyslexia. As a first step have the child's eyes examined to eliminate physical barriers to normal seeing.

Coordination problems are usually undetected. In many cases the child develop the habit of using only one eye to keep vision clear. This is a situation that may eventually lead to a condition called Ambliopia (where the brain switch off the deficient eye).

Eye coordination problems are exceptionally easy to correct without glasses.

There are very simple test you can make to determine whether your child has good eye-coordination or not. In the Magic eyes workshop you will also learn how you can re-educate the brain of your child to coordinate his or her eyes perfectly. In most cases this process takes only a few hours of exercise at most a few days. Research indicates that Vision Training is effective in more than 80% of the cases treated.
