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)
Lazy Eye (amblyopia) Amblyopia â often called lazy eye â is a problem that is common in children. Amblyopia is a result of the brain and the eyes not working together. The brain ignores visual information from one eye, which causes problems with vision development. Treatment for amblyopia works well if the condition is found early.
