You might be wondering about myopia and astigmatism and how they are different from each other.
You need a different type of glass for astigmatism because the cause of the blur between Astigmatism and other refractive errors is actually very different. But there are glasses that can function as both, that’s why you can see glasses that can correct both astigmatism and myopia together.
Astigmatism uses a cylindrical lens since it is a refractive error different from Myopia or Hyperopia. In Myopia, light is focused before the retina, and after the retina if hyperopia. While astigmatism refracts light in a different spot. Thus, a different kind of glass is needed to solve the issue.
Can you wear normal lenses with astigmatism?
Normal glasses is different with the glasses for astigmatism since astigmatism glasses corrects cylindrical error. People with astigmatism have a blurry vision in all distances, while normal glasses corrects you vision depending on what distance you can see clearly.
Thus, wearing normal glasses for astigmatism will not solve the problem, you need to get the right prescription in order to correct astigmatism.
Another thing to point out is that if you have a very low astigmatism which is about 0.75 below, you can use a normal lens if you have myopia. Since in actuality 0.6 below astigmatism is considered normal.
However, if you are working in a job where attention to details are necessary such as paper works and visually demanding jobs, you might need to wear astigmatism lens to prevent any errors.
Also, if you experience discomforts such as dizziness and nausea, uncorrected astigmatism may be a culprit. In this case, you may check with a qualified health professional to get a proper diagnosis and treatment.
Can you get glasses just for astigmatism?
There are glasses just for astigmatism because there are people who have 20/20 vision have astigmatism. This is because astigmatism is caused by another type of refractive error.
In astigmatism, light is refracted in a different direction so you need to correct things out. This is also the reason why people with astigmatism also have a poor night vision.
In myopia and hyperopia, light is refracted either before or after the retina, causing the person to see poorly from a specific direction. This could be not seeing things clearly when objects are far (Myopia) and not seeing things that are near (Presbyopia).
Astigmatism on the other hand, is not affected by distance and blurs things out regardless of the object’s distance.
What level of astigmatism require glasses?
|Astigmatism in Diopters||Level of Astigmatism|
|0.6 – 2.0 Diopters||Mild Astigmatism|
|2.0 – 4.0 Diopters||Moderate Astigmatism|
|>4.0 Diopters||Severe Astigmatism|
You do not need to wear glasses if you have astigmatism unless it affects your quality of life or it causes you some discomfort such as dizziness and headaches.
In fact, astigmatism and glasses has no correlation with each other when it comes to making astigmatism better or worse. A research paper titled: “Reduction of Astigatism after Infancy in Children Who Did and Did Not Wear Glasses and Have Strabismus.“ concluded that they found no significant correlation between the two.
Thus, if you don’t want to wear glasses, as long as you don’t feel any difference in your quality of life, you may do so.
If you really need to see clearly, then it will be perfectly fine to wear astigmatism lenses.

In fact, in a research paper from the World Ophthalmology Congress states that just as little as -1.0 diopters uncorrected astigmatism can cause a signifant difference in a person’s quality of life. So if you really need to wear astigmatism glasses, you are free to do so and it won’t make things worse.

What do people with astigmatism see?
People with astigmatism can see the following: Double or Twofold Vision, Blurred vision in all distances, Squinting to center objects and poor night vision. All of which are greatly associated with astigmatism, and may need a guidance of a health professional if you experience this.
In actuality, people with astigmatism can really find it hard to see texts, lines and at night. This is because of the improper refraction of light in their eyes.
Texts and lines appear to be doubled due to this. Making it confusing to read and one of the reasons why people with a high astigmatism always feel discomforts such as dizziness, nausea and headaches.
Same with lines. People with astigmatism can’t see lines well because of the double vision. It can be visually explained by this photo.
In this photo, you can see what people with astigmatism can see. It may just seem blurry but in actuality, this is caused by doubling vision. The lines appear to be out of the place it should be, causing the person to try or squint to force it to center.
This makes people with astigmatism bad at checking on where an object is because of the double vision.
Another thing worth taking note is their night vision which can be shown in this photo.
Lights are extended in a person with astigmatism, causing it to be hard to see things at night. In fact, because of this, people with astigmatism are very sensitive to light causing them to see bad.
Try this experiment:
- Open the lights in your room at night – This means that your eyes will adjust to the light around you making it less sensitive to light.
- Close the lights immediately – A few seconds after closing the lights, you will experience that you really can’t see well in the dark. This is because your eyes have adjusted to extreme light conditions and when it suddenly got dark, it has not adjust yet. This is the same with people with astigmatism, since lights are quite enhanced but to the extended lines, it will be hard for them to adjust at night.

Do I need to wear glasses all the time for astigmatism?
Choosing to wear or not wear glasses have factors to check on: if you are experiencing a decreased quality of life due to blurred vision, or if you feel discomfort because of uncorrected astigmatism. Other than that, choosing not to wear astigmatism glasses won’t make your eyesight worse.
As stated by a study stated above, glasses and worsening astigmatism are not correlated with each other. So you are free to choose.
Can astigmatism be cured?
There are numerous ways to treat astigmatism, the most accepted way is through surgery with has 90+% success rate. It is fast but the disadvantage is it can be quite costly.

I believe that tools are essential, especially in improving our lifestyle. Because I am a minimalist, I only buy things that add value to my life.
In this part, I will give you the tools I use for improving my eyesight.
First, let’s start with something free. The Myopia Calculator is something I’ve personally made for my viewers.
Go to the Myopia Calculator I’ve coded, which will give you the details you need to start print pushing and active focusing.
I also have video instructions in that blog post, making it easier to use the tool.
Active Focusing Full Course!
So you want to do active focusing but don’t know how? I got you covered with a completely free course!
You can visit the course here: Improve Eyesight Fast: Full tutorial with Proof.
Alright, who am I giving tips on how to reduce your eye grade? What’s my story?
You can find my whole story here: How I reduced my Myopia
Another free tool where you can learn more about eyesight is on YouTube.
While I do not make eyesight videos anymore, many YouTubers are out there that teach how to reduce your eyesight.
However, I am not one of them.
Of course, if you want to follow me, you can find my Channel by clicking the button below.
Have a suitable measuring device. I don’t recommend cloth or simple tape measures since you must always stretch it hard when measuring.
Get a simple heavy-duty tape measure since you need to pull it out. You can also see that I’m using this measuring device in my videos.
Blue Light Glasses
Okay, one of the things you will learn from me is that preventing eye strain means getting enough sleep. Guess what? Blue light affects our sleep a lot.
That’s why I recommend wearing Blue Light Glasses at night about 2 hours before bedtime. That way, you will be sleepy enough and have a good night of sleep.
I use a yellow-colored one since it blocks the majority of blue light.
Reading Glasses/ Positive Lens
A quick warning. Do not use a positive lens if your eye grade is more than -2.00. You do not need one if your eye grade is still high.
But always get a good quality pair of these glasses since low-quality pair of positive lenses might not be very accurate.
Furthermore, some of these cheap pairs are not optical grade, which means their surface is not smooth. Non-optical grade glasses confuse the eyes.
If you are in the last stages of print pushing (-2.00 below), don’t waste your efforts by having a low-quality positive lens.
While there is a simple test for checking positive lens quality, it would be better to ensure that you have a high-quality lens.
So I recommend this positive lens which is lightweight, scratch-resistant, and accurate.
Negative Lens/ Myopia Glasses
This is one of the problems of most of my viewers; however, I’m sorry, but as of this time, I can’t give you recommendations on where to buy a pair online.
I am just lucky to befriend an optometrist who helped me get the grade I want. Let’s see in the future if I find anyone that would offer to help us get one online.
Of course, I will check their quality myself before recommending anything.
