Vision Disorders: Astigmatism



Those who have astigmatism know that this is a refractive error that takes place in the eye. What it does it cause blurred vision in a similar fashion to farsightedness or nearsightedness. This is one of the most common reasons why people must visit an eye doctor, as it can be extremely frustrating when attempting to see into the distance or trying to read, only to have your vision impaired. Those who believe that they have this eye problem should see a doctor immediately because it can pose a danger to those around you.

When you suffer from astigmatism, your eye is unable properly pick up the light, as it does not focus squarely on the retina. When light enters the front of the eye, it bends this light and then points it back towards the eye's surface. If things are not lined up perfectly, vision problems will occur. This can occur if the eye is too long or too short in length, as this make it difficult for the eye to pick up on the light. It can also occur as a result of the cornea or lens being misshapen, as this affects where the light hits the retina. When you have astigmatism, your cornea will have a strange curve to it, which forces the light away from the retina. This causes blurriness and makes everything that you see appear to be out of focus. In many cases, those who suffer from this eye problem will also have nearsightedness or farsightedness.

astigmatismOne thing to keep in mind is that this eye condition can also occur after you have gone through an eye surgery, as it does not always occur naturally. In these cases, the cornea's integrity will be compromised as a result of the surgery. Cataract surgery is particularly dangerous in regards to this disorder, as the cornea can easily be changed throughout process.

The major symptom that you will have to look out for with astigmatism is the inability to see fine details within an object. This can occur at either a great distance or from up close, although you must use reason when attempting to come to a conclusion. For example, no one can see small details on an item from hundreds of feet away, but you should be able to see some details from this distance. Use common sense before becoming too worried about any potential eye problems you might incur.

If your astigmatism is extremely minor, you will not have to worry about having it corrected. It is something that you can live with and it will usually not get any worse. In more severe cases, you might need glasses or contact lenses to correct this eye problem. This should not interfere with your daily life too much, as it is simply a minor issue that will be taken care of in this way. Of course, more severe cases will call for LASIK surgery, which is a laser surgery that will change the shape of your cornea. LASIK surgery can also correct nearsightedness and farsightedness, so it will take care of all of your eye afflictions at once. Any one of these methods should return your vision to normal, so it is well worth looking into.

You will want to make sure that you have your astigmatism corrected immediately if it is a more serious case, as an uncorrected case in one eye can cause amblyopia. Amblyopia is also referred to as having a lazy eye and reduces one eye's ability to see details. This can cause rather significant vision problems, so it is best to have it taken care of as soon as possible.

If you believe that you have astigmatism, but your glasses are not taking care of the problem, make sure that you get in to see an eye doctor. This is because it can signal major eye problems, since glasses will usually correct the issue. You can also become a risk to others if you do not take care of your eye problems, making it well worth your while to have these issues looked at early. It is never too early to have this problem examined, so get into the doctor as soon as possible if you believe that you are suffering from any vision problem.
