When reading is a challenge, the issue may be eye-related -
for example, impaired vision or an inability to focus properly


Some people’s eyes struggle with ‘tracking’ – moving along a page or screen to follow text. Some possible reasons for tracking problems are outlined below.

Focusing - If a person’s vision system does not work properly, their sight may blur. This is also known as accommodative dysfunction. If so, the concentration required to focus on letters can be tiring, especially for children. However, the problem can be treated with prescription lenses.

Teaming - The muscles around the eyes help them move in tandem. If they are not properly coordinated, a person may experience blurry vision, and struggle to follow text. Lazy eye (amblyopia or strabismus) can result in teaming problems, and both conditions primarily affect children. But people with permanent strabismus, where one eye is constantly turned away, tend not to struggle with reading, as they only use the better eye to process text.

Peripheral vision - Some people have a limited field of vision, and may not be able to process a whole word, phrase or sentence as a result. Prescription lenses can expand the field of view.


Besides tracking problems, difficulty reading could be a symptom of one of the following eye conditions.
