Comment Lazy eye? not exactly. (Score 1) 386
The term lazy eye is used for a related condition called amblyopia, not strabismus itself. Strabismus causes double vision because both eyes are not aligned in a manner that allows the brain to fuse both pictures together to form a single 3D image. The brain attenuates the signal from the misaligned eye in order to reduce double vision. The reduction of vision in that eye is a condition called amblyopia, or lazy eye. Since you need 2 eyes to form a 3D image, people with amblyopia have reduced depth perception.
Looking at 3D TV isn't doing to give you strabismus or amblyopia. The risk to children is that until a certain age, the section of your brain that controls 3D fusion is still developing so if they spend all their time looking crosseyed at a tv, the brain may calibrate itself to provide fusion while the eyes are crossed. That would result in double vision when the eyes are properly aligned. That's why it's important to have a child treated for strabismus as early as possible.
