Accommodative insufficiency
Accommodative Insufficiency
Accommodative insufficiency (/əˌkɒməˈdeɪtɪv ˌɪnsəˈfɪʃənsi/) is a common type of non-strabismic binocular vision anomaly where the eyes fail to focus properly on near objects. This condition is often associated with symptoms such as blurred vision, headaches, and eye strain, especially during close-up tasks.
Etymology
The term "accommodative insufficiency" is derived from the word "accommodate" which in this context refers to the eye's ability to adjust its focus, and "insufficiency" which means inadequacy or lack of sufficiency.
Symptoms
Symptoms of accommodative insufficiency include:
- Difficulty focusing on near objects
- Blurred vision
- Headaches
- Eye strain
- Difficulty reading or doing close work
- Double vision
Causes
Accommodative insufficiency can be caused by a number of factors including:
- Aging: As people age, their ability to focus on near objects decreases, a condition known as presbyopia.
- Certain medical conditions: Conditions such as diabetes, multiple sclerosis, and Parkinson's disease can affect the eye's ability to focus.
- Certain medications: Some medications can affect the eye's focusing ability.
Treatment
Treatment for accommodative insufficiency typically involves vision therapy, which includes exercises designed to improve the eye's focusing ability. In some cases, corrective lenses or eyeglasses may be prescribed.
