Overview of Refractive Disorders
Symptoms of Refractive Disorders
A person who has a refractive error may notice that vision is Blurred Vision for distant objects, near objects, or both. For example, a child who becomes nearsighted may have difficulty seeing the chalkboard in school. People may sometimes have headaches caused by squinting or frowning. In children, frowning and squinting when reading and excessive blinking or rubbing of the eyes may indicate the child has a refractive error. Refractive error can contribute to eye strain (eye discomfort and fatigue), which occurs when a person stares for a long time trying to read or while working at a computer; the eyes can dry out and become itchy, red, or irritated, and vision seems temporarily blurred.
