This highly informative article will describe the history of astigmatism, how it can be treated, and other valuable information about this issue that is worth learning about.
What is Astigmatism?
Astigmatism is a variation of the eye’s natural curvature which can cause blurry or distorted vision. Astigmatism is thought to be caused by the cornea and lens not lining up perfectly in one’s eye. The most common form of astigmatism, called moderate astigmatism, occurs in about 29 percent of the population. It can result in blurred vision primarily when looking at close objects or reading. Severe astigmatism, which affects about 5 percent of people, can cause complete blindness.
The History of Astigmatism
The history of astigmatism dates back long before anyone could actually see through an obstruction in their vision. Some believe that astigmatism may have been caused wheneor eyes shifted while the human skull was still forming. Scientists aren’t sure exactly how astigmatism develops, but they do know that it can be treated with glasses and medications.
In more recent times, the cause of astigmatism has been better understood. It is now known that astigmatism is actually a result of focused light causing distorted vision. Over time, the lens of the eye becomes adjusted to these distortions and people with astigmatism see objects incorrectly. Astigmatism can be treated with eyeglasses or contact lenses, but it often requires several tries before the desired effect is achieved.
Six Common Causes of Astigmatism
Astigmatism is a common vision problem that can range in severity from barely noticeable to debilitating. Whether you’re struggling to read text or see anything clearly at all, you may be suffering from astigmatism. Here are six of the most common causes of astigmatism:
– Aging: As we age, our eyes lose their elasticity, which can cause them to become more prone to Issues with Astigmatism.
– Environmental Factors: Exposure to ultraviolet light (from the sun or lamps), smoke, and other environmental pollutants can cause your eyes to become more astigmatic.
– Genetics: Some people are born with a predisposition to developing Astigmatism, although it doesn’t always appear immediately after birth.
– Accumulated Injury and Problem Eyebrows: rigorous facial expressions such as frowning or squinting can lead to problems with the alignment of the eye’s lens, which in turn can lead to Astigmatism.
-eyedrops and other medications: Many over-the-counter medications -including those for allergies and pain -can leave your eyes dry and irritated, which can trigger Astigmatism.
Symptoms of Astigmatism
There are many symptoms associated with astigmatism. These include: blurred vision, halos around lights and other objects, difficulty seeing in close quarters, and reduced peripheral vision. Astigmatism can be a hassle to deal with, but it doesn’t have to be. There are plenty of ways to help mitigate the effects of astigmatism.
Some of the most common methods used to treat astigmatism include eyeglasses, contact lenses, and surgery. Eyeglasses are the most common method used to treat astigmatism. They help by correcting the shape of your eye’s lens. Contact lenses can also help improve your vision by replacing your glasses or providing a focal point in your blurry field of view. Surgery is also an option for treating astigmatism. It can be used to correct the shape of your eye’s lens or correct refractive errors (abnormalities in your eyes’ ability to see things straight).
There are several ways to manage and cope with Astigmatism – and let’s face it – no one enjoys feeling like they have significant vision impairment. But by taking some simple steps such as wearing corrective eyeglasses or contact lenses, we can make a big impact on our overall
Surgery for Astigmatism
There is no one answer to the question of whether or not astigmatism requires surgery. Many factors, such as the type and severity of astigmatism, must be considered when making a decision. In general, though, most astigmatic patients will benefit from surgical correction.
Astigmatism is an abnormal curvature of the eye’s cornea, which can distort images seen on the eye chart. This condition can cause decreased vision in one or both directions, and often leads to headaches and other symptoms. A recent study found that almost 60 percent of adults over the age of 18 have some degree of astigmatism.
There are two main types of astigmatism: primary and secondary. Primary astigmatism is usually inherited and becomes more severe with age. Secondary astigmatism is caused by an underlying disease or injury, such as a head injury or infected open wound in the eye. Treatment for primary astigmatism typically includes eyeglasses and/or contact lenses. Treatment for secondary astigmatism may include surgery to correct the curve in the cornea.
The earliest known description of astigmatism comes from a Greek physician named Hippocrates (460-370 BC). He noted that
Matters of the Eye
Medical conditions affecting the eye have been known and treated for centuries, but one of the more common conditions is astigmatism. Here’s a brief history of astigmatism and what you can do to treat it.
A Brief History Of Astigmatism
Astigmatism is a condition in which the eyes are not evenly curved, causing objects viewed from different angles to appear blurred or distorted. The condition can be caused by numerous factors, including genetic susceptibility and environmental factors such as exposure to sun or eyeglasses. In some cases, astigmatism may be corrected with eyeglasses or surgery.
Astigmatism first became recognized as a medical condition in the 1600s. At that time, Hippocrates described abnormalities of the eye as “diplopia”, meaning double vision. In the 1800s, German ophthalmologist Albrecht von Graefe discovered that astigmatism was related to irregularities in the cornea (the clear front window of the eye). He subsequently developed an algorithm for treating astigmatic patients with glasses and contact lenses.
Today, astigmatism remains a common problem. The Centers for Disease Control and Prevention estimate that about 20% of Americans have astigmatism
Astigmatism has been a part of humanity since the beginning, although the various types and levels of astigmatism that exist today didn’t exist until recently. As medical technology advances, more and more people are suffering from this common eye condition, which can be frustrating and costly to treat. If you think you might suffer from astigmatism, speak to your optometrist or ophthalmologist about whether a treatment plan is right for you.
