What is astigmatism? We’re covering the causes of astigmatism, symptoms of astigmatism, treatments, and all the useful tips needed to manage this common condition.
In an ideal world, your eyeball would be perfectly round, infiltrating light that bends evenly. The result being crystal clear vision.
For the majority of the population, our eyeballs aren’t a perfect, round ball. This means that light will refract (bend) more in one direction than another, causing objects to look blurry as only part of them are in focus. This is astigmatism.
Most cases of astigmatism are hereditary. They typically derive from birth, and develop slowly. Other causes can be from:
Another possible cause of astigmatism is a rare condition called Keratoconus, whereby the structure of the cornea (that’s the clear, outer lens of your eye) isn’t strong enough to hold its round shape, and bulges like a cone.
A common misconception is that reading in low lighting or sitting too close to the television can cause astigmatism. This is not actually true, and most likely a tool our parents used to have us move further away from our cartoons!
Symptoms of astigmatism can differ in each person, with some cases actually being asymptomatic. There are a few common symptoms reported with astigmatism to look out for.
It’s worth noting that children may not recognize symptoms of astigmatism. If they are used to only seeing the world out of focus, they won’t identify this as a problem. It is therefore important to check their vision regularly.
Treatment is easy, and starts by going to the eye doctor in order to detect and diagnose the condition, in this case being astigmatism. Through a series of tests, your doctor will determine how the eyes bend light, and thus the prescription necessary to correct your astigmatism and/or other refractions, if there are any.
Fortunately, treatment is easy. After an astigmatism test, the most common way to correct astigmatism associated with blurred vison is with corrective eyeglasses or contact lenses such as these Acuvue Oasys for Astigmatism. With the appropriate prescription, perfect vision or substantial improvement can be achieved, as long as the corrective lenses are in use. Optometrists recommend annual eye exams to monitor the health of your eyes and ensure you are using the correct prescription.
For those looking beyond treatment the option of LASIK laser surgery is a highly successful one. It works by reshaping the cornea, allowing light to focus correctly on the retina (the tissue lining the back of the eye).
Laser surgery is not suitable for everyone, however. A full consultation with your eye doctor will outline all the risks and benefits, and determine whether or not you are a viable candidate to use Lasik to Fix astigmatism.
Astigmatism on the whole is extremely common, easily diagnosed with routine tests, and treatable. It shouldn’t negatively impact your day-to-day life, provided it’s managed properly.
If you think you may be experiencing the above mentioned, or any other symptoms, please schedule an appointment with your eye doctor.
