With normal vision, both eyes are aimed in the same direction and see the same image. The brain then blends these 2 images together into 1 clear, 3-dimensional image. This is called binocular vision. Children with strabismus often have difficulty with double vision because each eye is seeing a slightly different image. Over time, the brain starts to ignore the image from the turned eye in an attempt to avoid double vision; this is called suppression. Over time, the child may lose depth perception and even lose vision in the turned eye.
