Chronic pain: Pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Less common conditions that can cause a lazy eye include: 1  an eye disease such as a sore on the transparent layer at the front of the eye (corneal ulcer) or a scar. 2  childhood cataracts â clouding of the lens of the eye that's present from birth. 3  a droopy eyelid (ptosis)
Amblyopia (lazy eye) is the loss or lack of development of vision in an eye that is unrelated to any eye health problem. The brain, for some reason, does not acknowledge the images seen by the amblyopic eye. Reduced vision due to amblyopia is not correctable with lenses alone.
