Imagine this scenario. An adorable little girl, Kaitlin who is soon to be 5 years old and getting ready to go into Pre-Kindergarten. But, before she starts school her parents decide to have her eyes examined with their local optometrist.

At age 18, Emily is a bright and talented young lady. In her senior year of High School she is also on the school’s swim team, a sport that she could excel, even with no depth perception. Yes, Emily’s story begins with stereo blindness.

Amblyopia, otherwise known as “lazy eye”, is the most common cause of preventable blindness in children. While the loss of vision usually occurs in one eye, rarer forms of bilateral amblyopia do exist. This type of “blindness” occurs in approximately 2 out of 100 healthy children.
