Astigmatism, a major refractive error, can cause blurriness while viewing things. When either the cornea or lens becomes more curved than usual, light rays do not converge on the retina, creating a virtual image that is difficult to focus on. The symptoms are similar to hypermetropia, and if left untreated, it can lead to a gradual decline in vision. Worry not - we are here to guide you through the possible diagnostic methods to detect astigmatic eyes. Keep reading to uncover the details!
Normally, the curvature of the eyes is maintained so that light rays can focus on the retina. However, a person affected with astigmatism has a much rounder and steeper curve, similar to that of the back surface of a football. As a result, the incident rays suffer a sharper bend, thus negatively affecting vision. Over time, the eyes lose their ability to focus, especially on closer objects. Common treatment methods include wearing eyeglasses and contact lenses, with the most reliable option being refractive eye surgery!
As per the American Academy of Ophthalmology findings, around 33% of the US population suffers from astigmatism. This is irrespective of age, race and gender, as recent reports say that even babies may have this condition. While some outgrow this condition, many of them suffer from future complications. Thus, one must prioritize astigmatism and not leave it untreated.
Depending on the unevenness of the corneal surface, astigmatism can be classified into three main types. They are as follows:
(Note: Some people may face both corneal and lenticular astigmatism at the same time.)
As mentioned, blurry sight is one of the most common signs of astigmatism. This makes it difficult for people to visualize detailed images, regardless of how close the object is kept. However, the list does not end here; here's what you can expect.
It's crucial to note that some young children may not be aware of their astigmatism until it has progressed significantly. Therefore, scheduling a visit to an eye specialist is of utmost importance for early detection. As a parent, it's your responsibility to be vigilant for signs such as frequent eye rubbing, complaints of headaches, and arrange for an eye checkup promptly. Your vigilance can make a significant difference in your child's vision and overall well-being.
Astigmatism is highly genetic, meaning that individuals with one or both parents affected are at a high risk of developing it. It can also happen due to the eyelids unnecessarily pressurizing the cornea. The following is a list of certain health conditions that can trigger astigmatism.
Astigmatism, when left untreated for long, leads to severe headaches, difficulty focusing on objects, etc. However, in severe cases, permanent visual loss may happen.
After you visit an eye clinic, the ophthalmologist will perform an optical exam. But before that, he will ask a few questions, such as:
Here's a list of methods that eye specialists employ to diagnose your eyes for any internal abnormality. These are as follows:
The standard treatment for astigmatism is corrective lenses. However, depending on the extent of the problem, the eye care specialist will prescribe eyeglassesor contact lenses to aid in clear vision. In case your astigmatism is moderate and does not affect vision much, there is no need to put corrective eyewear. Visiting the ophthalmologist regularly makes it possible to monitor changes in your lens shape and know if any further testing procedure is required. Remember, astigmatism can change with time and get worse. Thus, it is best to attend follow-up visits, even if you feel apparently 'fine'.
Wearing glasses or contacts helps manage vision but does not restore the shape of your eye surface. Several sophisticated surgical methods are available that can help permanently solve your refractive issue. The most common is vision correction surgery, such as LASIK eye surgery, photorefractive keratectomy, or PRK eye surgery. A specially trained eye surgeon will perform these procedures to rectify the de-shaped cornea so that light rays can hit the retina optimally and promote visual acuity.
The best way to prevent astigmatism is to get regular eye checkups from an ophthalmologist. The frequency usually depends on the suspected person's age. Below is a list.
(Note: In case you wear corrective glasses or lenses and have metabolic disorders like diabetes, you are required to visit an ophthalmologist more often, like after every six months.)
Although there is no going back after you catch up with astigmatism, following the tips below can help prevent it.
If you notice any continued change in vision, especially a sudden feeling of discomfort or blurry vision, consult an ophthalmologist as soon as possible. Generally, people with astigmatic eyes face problems seeing at night or during rainy days, etc. Thus, treat it as vital and arrange a timely eye checkup before it gets too late!
Similar to other refractive eye disorders, astigmatism cannot be fully cured. But the good news is that you can manage it with timely treatment to prevent further worsening. Thus, if you have difficulty viewing nearby objects, do not sit back for long. Come to us at Vision Cure Clinic and embark on a crystal-clear perspective today!
A person with astigmatism may see things as blurry and distorted. He may also experience glares and halos.
Astigmatism is a gradual and slow process, and one remains unaware until severe consequences appear after a long time. Thus, it is recommended that you visit an ophthalmologist and quickly test your eyes.
During an optical checkup, the doctor conducts various eye exams. These involve measuring the curvature of the cornea, estimating the refractive ability of the eyes, and so on.
The prime cause of astigmatism is an unevenly shaped cornea. This causes light rays to bend sharply and not converge into the retinal layer, resulting in distorted vision.
As mentioned, about 1 in 3 people worldwide have astigmatism, and most of them have all three refractive eye disorders.
The first line of treatment for astigmatism is usually corrective lenses, such as glasses and contact lenses. However, if the condition is severe, ophthalmologists will prescribe refractive eye surgeries like LASIK.
