A Complete Guide to Astigmatism: Everything You Need to Know

Don't let the name scare you - astigmatism is a common condition that can easily be managed with the right eyeglasses. Get all the facts and tips you need here!

If you've ever wondered about the meaning of "astigmatism," you're not alone. This commonly misunderstood condition is often mistaken for a serious eye disease, causing unnecessary worry. But fear not! Astigmatism is actually quite prevalent and not as alarming as it may appear. In fact, many individuals are unaware of its presence until a knowledgeable eye doctor uncovers it. Ready to dive deeper into this topic and learn how to deal with astigmatism? Let's get started!

What Does Stigmatism Mean?

Stigmatism is a common vision issue that occurs when the cornea or lens is unevenly curved. This unevenness leads to blurry or distorted vision, affecting millions of people worldwide.

There are three types of stigmatism: myopic, hyperopic, and mixed. Myopic stigmatism, commonly known as nearsightedness, causes difficulty focusing on distant objects. On the other hand, hyperopic stigmatism, or farsightedness, makes nearby objects appear blurry. Mixed stigmatism combines aspects of both nearsightedness and farsightedness, resulting in a complex visual challenge. 

Stigmatism can occur due to various reasons, including genetics, injury, or surgery. Recognizing the signs of stigmatism is crucial for early intervention. Common symptoms include headaches, eye strain, and difficulties seeing in low light conditions.

What Does Astigmatism Look Like?

Astigmatism occurs when the front part of your eye, called the cornea, isn't perfectly curved. Instead, it takes on a shape that causes light to focus on two points on the retina instead of one. The result? Blurred vision, reduced clarity, and sometimes even double vision.

Medical professionals are still unsure of the exact reason behind the irregular shape of the cornea or lens. While the cause remains unknown, there are factors that can contribute to this condition.

  • Premature Birth: Interestingly, infants born prematurely are more susceptible to developing astigmatism compared to those born at full term.

  • Life's Impact: Surgery, illness, or corneal scarring from an eye injury may lead to astigmatism later in life.

  • Keratoconus: An eye condition called keratoconus, where the cornea thins and changes shape over time, is another cause of irregular astigmatism.

Is Astigmatism Bad?

Astigmatism is a common eye condition that often leads to eye strain and fatigue, resulting in decreased performance at school or in the office. While typically not a serious issue, astigmatism can occasionally mask a more severe vision problem. This refractive error, along with nearsightedness and farsightedness, can be effectively managed.

Astigmatism Lights vs Normal Vision

If you've experienced squinting or sensitivity to light, you might be dealing with astigmatism. Surprisingly, individuals born with this condition often perceive their vision as normal until it's pointed out to them. On the other hand, those who develop astigmatism gradually notice changes in their eyesight, quickly differentiating between blurry lights and clear vision.

Lights affected by astigmatism can appear fuzzy, streaky, and surrounded by haloes, particularly at night. The underlying cause is a cornea that fails to transmit light, resulting in scattered visuals properly. In contrast, those without astigmatism experience lights with a softer halo, thanks to their perfectly spherical corneas that allow light to flow effortlessly onto the retina.

Astigmatism at Night

If you have astigmatism, you likely experience consistent eyesight throughout the day. However, nighttime can amplify the blurriness due to the stark contrast between light and darkness. 

As the light dims, our pupils naturally dilate, welcoming more light into our eyes. However, this dilation can trigger increased glare and streaks for individuals with astigmatism when gazing at night lights. 

Is it Safe to Drive at Night with Astigmatism?

When it comes to astigmatism, driving at night can be a dangerous endeavor. However, you can minimize the dangers by wearing the right glasses. These glasses work by altering the path of light before it enters your eyes, effectively diminishing glare, halos, streaks, and overall blurriness. With this advanced solution, you can maintain a clear focus on the road ahead. 

How Lights Truly Look Without Astigmatism?

If you don't have astigmatism, your cornea and lens are as smooth as a perfectly spherical bowling ball. This crucial detail allows light to reach your retina, giving you a crystal-clear image effortlessly. Just imagine the brilliance of sunlight but with less glare and no light sensitivity. Colors are more vibrant, and even at night, you'll be amazed by the clarity of lights without any haziness.

How Does Astigmatism Impact The Way We See Light?

Well, it doesn't just impact distant vision; it also alters how lighting appears on objects nearby. This eye condition causes light rays to refract in multiple directions, leading to blurred vision and reduced sharpness, regardless of the object's distance. Moreover, the presence of astigmatism distorts the shape of lights, stretching them out and giving them a starburst-like appearance, thereby distorting our perception of their actual form. 

Can Astigmatism Make You Sensitive to Light?

Absolutely! Astigmatism can indeed cause light sensitivity, but the level of sensitivity can vary. Essentially, astigmatism affects how much blur an eye perceives in different directions. If you don't have astigmatism, your vision would be equally blurry in all directions, and the chances are that light sensitivity would not be an issue for you. However, if your vision is blurrier in at least two directions, then you're likely dealing with astigmatism.

It's important to understand that other visual impairments, like cataracts or keratoconus, can also trigger light sensitivity. Consequently, identifying astigmatism as the exact cause of your light sensitivity can be challenging without professional consultation.

If you're experiencing heightened light sensitivity, it is highly recommended that you schedule an appointment with an optometrist. 

How to Spot Astigmatism: Understanding the Signs

Blurry vision is a common sign of astigmatism. Besides, there are several other important symptoms to watch out for. If you're experiencing eye pain, discomfort, or frequent headaches, it's possible that you may have a more severe case of astigmatism.

Left untreated, astigmatism can negatively affect your coordination and overall physical performance. But don't worry! We have some good news for you. This condition is treatable, and managing it can be easily done. It all starts with being aware of astigmatism and knowing how to handle or live with it effectively.

To regain control of your vision and enhance your overall quality of life, it's crucial to schedule an eye exam with your trusted optometrist. With the right knowledge and a healthy routine, you can effectively manage astigmatism. 

Can Astigmatism Be Corrected? How to Fix Astigmatism?

LASIK laser eye surgery is a popular and effective solution among those seeking a remedy for astigmatism. But there are simpler alternatives that deliver excellent results. Corrective eyewear, like astigmatism light glasses, can provide relief.

What are astigmatism light glasses, you ask? They are eyeglasses equipped with a cylindrical lens designed to fix the irregular corneal or lens curves that cause visual distortion. They are an excellent choice, especially for individuals with severe astigmatism who find glasses more convenient than contacts.

Choosing the right pair of eyeglasses is crucial when considering astigmatism correction. By consulting your eye doctor, you can determine if astigmatism glasses are the ideal solution for your vision issues.
