It’s not every day that you see people talking about interesting facts about eyesight. But how much do you really know about your eye health? There are some who are blessed with perfect 20/20 vision, while others are completely blind.
But what about people with certain eye conditions? How can you tell if you have poor vision at all? Twitter’s recent post has spread like wildfire and fueled responses from around the world. It’s making people question their eyesight. The below tweet shows what vision with astigmatism looks like versus vision without astigmatism.
Here’s a Look at Vision with Astigmatism versus Clear Vision:
Astigmatism is when the cornea is slightly curved rather than completely round..

In the first image, the light from the brake lights and traffic sign appear distorted, stretching into a wide, starbust shape. This exactly indicates what vision with astigmatism looks like. In the second image, the lights coming off of the traffic light appear softer and have a halo shape, which represents clear vision.
This tweet has gathered over 80,000 reactions and has convinced many people they have vision with astigmatism. Most of the people who reacted thought the image on the left was a representation of perfect vision and the results have shocked them. Some people with glasses thought the distorted vision was actually a normal condition. But what really is astigmatism? And what does it tell you about eye care? Read on to learn more.
What is Astigmatism?
Astigmatism is the most common refractive error in the world and it causes blurred vision. In fact, the number of people with astigmatism outdoes those with conditions like nearsightedness or farsightedness. And it has to do a lot with the shape of your eye. Early astigmatism diagnosis helps you identify how severe your condition is.
Let’s say you have someone who has no astigmatism at all. Their cornea is perfectly round. Some patients have eyes shaped like a basketball, while others have a shape that resembles an egg.
If you have astigmatism, you have two different curvatures to mainly your cornea. And what is the cornea? It’s a window that sits over the colored part of your eye. So someone that has astigmatism has a steep part to the eye and the other side is a lot flatter.
And that creates two refractive surfaces when light enters the eye. So instead of having one power to your prescription contacts or glasses, you actually have two for vision correction.
Symptoms of Astigmatism
The symptoms of astigmatism may be different in each individual. Some may have all symptoms, while others may have just one or none at all.
Here’s a Look at the Astigmatism Symptoms:
- Distorted, blurry or fuzzy vision up close and far away
- Trouble seeing at night
- Eye Irritation
The viral tweet you just saw definitely lives up to its claim. Blurry vision, headaches, dry eye, eye strain, and squinting are symptoms you should not be ignoring. Now that you’re aware of the symptoms, check with your family members if they experience the same. You should also ask your eye doctor about what causes astigmatism.
Show them the tweet if necessary and make them identify which image they usually see. Since astigmatism is a common symptom, it can be easily treated with eyeglasses, contact lens, and laser surgery.
Children are prone to astigmatism and it can affect their learning growth if not corrected quickly. Eye vitamins are also essential for growing kids. Also, an eye exam is important not just to correct blurry vision, but it is to safeguard your overall health and wellness.
Don’t put it off for any longer. Schedule an appointment with an experienced eye doctor in Fresno, CA to correct your vision.
