When a kid has strabismus, the eyes don't focus together on the same object and each eye sends a different picture to the brain. As a result, the brain might see two images (double vision) or the object looks blurry. Kids' brains are really smart, and they don't like getting two different pictures instead of one.

A dilated pupil sometimes can still react to light — that is, get smaller in bright light or when a light is shined at the eye. But typically, dilated pupils don't respond normally to light. A large pupil that is completely unresponsive to light is called a "fixed" dilated pupil.

So, using a camera's flash on babies will not cause any damage to their eyesight, let alone blind them. Whenever there is a bright light, the pupil in the eye constricts for protection.
