Why is poor eye accommodation a problem

Accommodative Infacility Difficulty efficiently switching focus between near and far and back. Accommodative Spasm A spasm of the focusing muscle which prevents the focusing muscles from fully relaxing. Physical Symptoms of Accommodative Dysfunctions Blurred vision at near Intermittent blurred vision at distance after reading Difficulty switching between near and far Eye strain Headaches- especially over the brow or temples Eye fatigue General fatigue, especially later in the day Symptoms often are worse when tired, later in the day or during tasks People with Accommodative Dysfunction may also avoid near point work like reading or writing, they may hold material they are reading very close or very far away from their eyes, or they may have poor reading fluency or comprehension.

Optom Vis Sci Vol 83, No. If you are nearsighted then distant objects are blurry, you wear glasses that help bend the incoming light so it hits the back of the eye.

Farsighted people use a specific lens that bend the light to help make near objects clearer. The lens in your eye works this exact way except for one difference: it can bend to help you see both near and far and change power nearly instantaneously. A muscle known as the ciliary body works to flex the internal lens and change its focal power accordingly.

This is known as accommodation and it allows you to focus on near and far objects interchangeably depending on where your brain tells your eyes to focus. However, there are times when your accomodation ability can be compromised. A common problem involving accommodation is accommodative dysfunction. This leads to blurred vision at close, especially when reading. Although it rarely causes infection, when it does occur, it can threaten your vision.

Amblyopia—also known as lazy eye—is the loss or lack of development of clear vision in one or both eyes. Anterior uveitis is an inflammation of the middle layer of the eye. This middle layer includes the iris colored part of the eye and adjacent tissue, known as the ciliary body.

Kids with focusing problems may appear to learn normally, but they may become frustrated quickly especially as school demands increase. Over time, this may cause the brain to ignore the affected eye, a condition called amblyopia or lazy eye with its own associated problems.

Some focusing dysfunctions are caused by basic vision problems such as long-sightedness, short-sightedness or astigmatism. Treatment may be as simple as providing spectacles to correct a refractive error. If spectacles are needed, our qualified optical dispensers will help you select the best lens and frame for your child.
