Astigmatism in Child in Houston
Is Characterised by an Irregular Curvature of the Cornea
Astigmatism is a common eye condition that's easily corrected by glasses, contact lenses or surgery.
This type of disorder is also known as a refractive error. Astigmatism occurs in nearly everybody to some degree. For significant curvature, correction is required.
A person's eye is naturally spherical in shape. Under normal circumstances, when light enters the eye, it refracts evenly, creating a clear view of the object. However, the eye of a person with astigmatism is shaped more like a rugby ball or the back of a spoon. For this person, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at certain distances can then appear blurred.
What causes astigmatism? - Astigmatism can be hereditary and is often present at birth. It can also result from previous eye surgery, trauma to the eye and certain congenital conditions.
What are the symptoms of astigmatism? - The most common symptom of astigmatism is blurred vision. If you are only slightly affected, you may not notice that much is wrong with your vision. More significant astigmatism may cause noticeable vision problems.
It is particularly important to remember that children with vision problems may not realise their vision is blurred. After all, they may never have seen the world in focus. That’s why it’s a good idea for children to have regular eye tests.
Here are some symptoms of astigmatism:
- Blurring of small print, difficulty reading
- Inability to see both near and at a distance without squinting
- Sensitivity to light
Children with vision problems such as astigmatism may experience:
- Difficulty focusing on printed words and lines
- Eyestrain, tired eyes or headaches
