Definition: An accommodative spasm is a condition that causes the eye muscle to accommodate or focus constantly and automatically. For example, a person may be concentrating on a close task, such as reading. When they look up, their vision is blurry. Their eye is still focusing on a close-up or near task, even though they are now looking at a distance. Thus, a person with accommodative spasm has a difficult time relaxing the focusing muscle when looking at a distance.
