Astigmatism vs. normal: all you need to know
Astigmatism is a kind of vision problem that is much more common than we think. In fact, there are plenty of people who have astigmatism and do not even realize it. This is because a lot of cases are so mild that it does not really affect one's vision, nor does it require correction. But what is it exactly? How do you know you have it, and what can you do for treatment? Read on to find out everything you need to know.
What Is Astigmatism?
Astigmatism is what you have if your eye is not perfectly round, as it should be. If you compare eyes with astigmatism vs. normal eyes, the former would be noticeably more curved. The eye with astigmatism might look like the back of a spoon, or a football. This leads to refractive errors – when light enters the eye, it will not bend at the correct angle, which then causes blurry vision.
There are actually two common types of astigmatism. Corneal astigmatism is when an irregular shape is in the cornea. But if the irregular shape happens in the lens of the eye, then it is called lenticular astigmatism. This second type often occurs as a result of cataracts.
What Is the Main Cause of Astigmatism?
People of all ages can develop astigmatism from a wide variety of causes. Despite the extensive research and comparisons between astigmatism vs normal vision, experts are still not entirely sure as to the causes of the condition.
Some people are born with it, which means it's highly likely that they inherited it from a parent. Many also develop astigmatism during childhood or early adulthood. Eye injuries, particularly those that put pressure on the eye, can also trigger the development of astigmatism. Statistics show that one in every three people has astigmatism, but most cases are mild and do not significantly affect your vision.
How Can Astigmatism Be Corrected?
The easiest and most popular way to correct astigmatism is by wearing corrective lenses. Eyeglasses and contact lenses can both help, and it's up to you to choose the more comfortable or practical treatment.
Of course, eyeglasses will only give you perfect vision while you are wearing them. Once you take them off, you will go back to the blurred vision that you have because of your astigmatism. If you are looking for a permanent solution, you can talk to your eye doctor about surgical solutions.
Surgery can correct the irregularities in your cornea or lens, giving you permanently clear vision without having to wear glasses or contacts. On the downside, it can be costly and is not practical for very mild cases.
Astigmatism vs. Normal Vision
If you are wondering whether you might have astigmatism, it would be best to see your eye doctor so that you can undergo the necessary tests. An ophthalmologist will give you a dilated eye test that will easily identify astigmatism vs normal vision. There is no need to worry about this test because it is very simple, quick, and painless.
But even before you go to the doctor, you can observe yourself and your vision for some of the common symptoms of astigmatism. In addition to the blurry vision, do you find yourself having to squint to see better? Do you frequently experience eye strain, and do you have trouble seeing after dark? Do you also experience constant headaches? If so, there's a good chance that you might indeed have astigmatism, and you should see your doctor to be sure.
Another common tell-tale sign of astigmatism is when you see a flare or a halo around light. This is most noticeable during nighttime. It is quite interesting how so many people think that these are normal, and that everyone sees them. But if you compare looking at lights with astigmatism vs normal vision, a person with perfect vision will not see any of these flares or halos. They might look pretty but they are an indication of an eye problem. So if you are one of the thousands of people who see them, it's time to get checked by an eye doctor.
How to Choose Glasses for Astigmatism?
As mentioned, wearing eyeglasses is the most popular treatment of choice for astigmatism. However, there are a few things you need to know before you go out and get fitted for astigmatism glasses.
The Right Kind of Lens
The kind of lenses that you need for astigmatism lenses are cylindrical or sphero-cylindrical. If you have astigmatism and are nearsighted or farsighted at the same time, your eye doctor will prescribe a special kind of glasses for you to wear. Progressive lenses can be a good option in this situation.
As for material, polycarbonate lenses are highly recommended for most cases. But for high degrees of astigmatism, you might want to ask for high-index lenses that will not be so much heavier or thicker despite the higher grade. No matter which type of lens you decide on, you have to make sure that it has an anti-reflective coating, which will reduce glare and keep them from obstructing your vision, especially during nighttime.
The Best Frames
There are really no rules when it comes to frame styles for astigmatism glasses. But since you would probably be wearing them the whole day, it is best to go for lightweight frames that are comfortable for extended wear. A flat front would also be advantageous in order to minimize visual distortions.
