Accommodative spasm

What is Accommodative spasm?

An accommodative spasm can appear after an activity such as long-time reading or playing video games, in which people are using their short-sighted vision. When people do such activities, they focus on a near object. Usually after stop doing so the eyes should stop focusing; however, the eyes of people with accommodative spasm keep focusing on the near, and that causes blurry vision at other distances. This is one of the reasons why children’s vision gets worse.

How is it treated?

Some patients find relief through the use of daily eye dilation with cycloplegic drops. This symptom can be affected by the lifestyle, so the improvement of your daily habit (e.g. Having good posture, reading in a well-lighted place and so on) may have good effect. It is also said that simple treatments like meditation, relaxation, or taking a vacation can help.
