Accommodative Disorders

When looking at an object at near, our brain adjusts the lens inside our eyes to increase our focusing ability to keep the object clear. With accommodative insufficiency, the eyes are unable to focus the correct amount at near which causes blurred vision, headaches, eyestrain, reduced accuracy with reading, and avoidance of reading and writing. 

With accommodative spasm or excess, the eyes focus too much when looking at objects either at distance or near. When this occurs, we can develop blurred vision, reduced efficiency and productivity, headaches or pain around the eyes, fatigue, and difficulty with visual concentration. 

Accommodative infacility is the inability or difficulty in shifting our focus from one distance to another. This disorder can be disruptive by causing blurred vision, inconsistent work, difficultly maintaining clear vision, headaches, difficulty with visual concentration, and moving print. This ability to shift our focus is important in the classroom when copying notes from the board and with playing sports.
