Amblyopia
"Lazy Eye," or Amblyopia, is easy to miss because there are very few symptoms. Lazy Eye means that the eye sees poorly, even with eyeglasses. Usually when parents see an eye that doesn’t seem to line up correctly, they think that is a “lazy eye.”
Strambisus
Eye turns (a condition called Strabismus), has to do with an inability to point both eyes in the same direction at the same time. One eye - or both, as in crossed eyes - may appear to turn in, or one eye may turn out, up or down.
Post-Concussion Vision Disorders
Probably one of the most important facts for parents to know when it comes to accidents and bumps to the head, is that your child does not have to be knocked unconscious in order to have a concussion. In fact, whiplash can cause a concussion, your child does not have to hit his or her head. The same holds true for adults.
Convergence Insufficiency
Convergence Insufficiency is an eye coordination disorder that can interfere with anyone’s ability to read and remember what they read. The important thing to understand is that one can pass vision screenings, even eye exams (meaning that you can see the letters on the eye chart you are supposed to see from 20 feet clearly) and still have an eye coordination problem.
Tracking Problems
If you think about how you use your eyes when you read, you will find that your eyes move a lot; back and forth along the lines of print. This is called Tracking, eye movement and also oculomotor skills. When the eyes don’t move together correctly it can cause you to lose their place when reading, have difficulty copying from the board or computer screen, and skip or omit small words when reading.
