I have a lazy eye. I have been wearing glasses but of little use. Will vision from a lazy eye get worse with time?

Some basics. Lazy eye is a lay term. Some use it to describe an eye that drifts in or out, not lined up with the other eye. Some apply it to a weaker eye. If the 2 eyes do not have the same strength, or one does not line up, it gives the brain 2 images. Over time (years) the brain can decide to turn off one eye & stay with the best image. Since your status is unclear it is unclear what your outcome could be. .
