Synopsis

Refractive Eye Disease is an eye disease occurring as a result of error in the focusing of light by the eye.

It results in poorer eye vision.

These are :

1. Myopia or short sightedness
where light comes to focus in front of the retina instead of on the retina.

2. Hypermetropia or Long sightedness
where light comes to focus behind the retina instead of on the retina.

3. Presbyopa or Far sightedness
where the ability to focus up close becomes more difficult due to age.
As the eye ages, the lens can not change shape easily to allow the eye to focus close objects clearly.

4. Astigmatism
where the eye can not focus light evenly onto the retina.
This can cause images to appear blurry and stretched out.

Who is at risk for refractive errors?
All refractive errors can affect both children and adults.
People with parents having certain refractive errors are more likely to get a refractive error.

What are the signs and symptoms of refractive errors?

Blurred vision is the most common symptom.
Double vision
Glare or halos around bright lights
Eye strain

How are refractive errors treated?

Refractive errors can be corrected with eyeglasses, contact lenses, or surgery.
Eyeglasses are the simplest and safest way to correct refractive errors.
