Understanding Astigmatism
Astigmatism is a common eye condition, in this article we explain the causes through to how it can be treated.
Astigmatism is usually caused by the shape of your eye; specifically an irregular shaped cornea. A regular cornea is symmetrically round and shaped like a football whereas an irregular shaped cornea is shaped more like an egg, or rugby ball. It is not known why this happens.
For this reason, astigmatism is usually something you are born with, although in some cases it may develop after an eye injury or illness. You may be more likely to have astigmatism if you are short or long-sighted.
In other cases, astigmatism may be caused by a distortion to the shape of the lens in your eye and is known as lenticular astigmatism. This type of astigmatism is not as common as corneal astigmatism.
Many people do not know they have astigmatism, instead focusing on the other refractive error present, such as being long or short-sighted.
An irregular shaped cornea will affect how light focuses on to the retina, very similar to other refractive errors; this can have several effects on your day-to-day vision
The most common symptom you may find with astigmatism is blurred vision, either when looking at close up objects or objects in the distance. You may also experience headaches; this is because your eyes will be working even harder to try and see clearly, which could put a strain on your vision.
If you have astigmatism, you might notice unclear peripheral vision. In some cases, you may have difficulty distinguishing specific shapes or details.
Eye strain is a common symptom of many eye conditions, including refractive errors like astigmatism. Eye fatigue may be particularly prevalent when you have been concentrating for a long time, perhaps either on the computer or reading.
It is very straightforward to correct astigmatism. Your optician usually prescribes glasses for astigmatism during an eye examination. It is vital to keep up with regular appointments to test your vision and check your eye health as your optician will be able to tell how severe your astigmatism is and can keep track of whether it is progressing with each appointment.

Eye fatigue occurs when our eyes are tired after intense use such as looking at a fixed object for a long time without taking regular breaks, but what can you do to prevent the uncomfortable symptoms that come with eye strain?
