Is amblyopia resolved if the amblyopic eye reaches 20/20 vision? Thanks

Maybe. Amblyopia is triggered when the brain decides to reduce/eliminate input from an eye that is weaker or giving double vision.Like turning off a camera. If the weaker eye can be brought to accurate vision, or the double vision eliminated by patching or surgery, amblyopia can sometimes resume. If it has gone on too long, it may not. Most at 7 can gain improvement.
