There is a chance that you just went to an eye check and the doctor said you have astigmatism and you are looking if you should wear a glass or not. Then this article will help you decide whether you should start wearing glasses or not. If there are side effects if you don’t want to wear them.
People with a prescription of 0.75 diopters astigmatism or more may need to start wearing glasses. Since 0.75 is already considered mild astigmatism, it can cause a significant reduction in the lifestyle or quality of life of people. The person’s occupation is also a factor if glasses are necessary.
In fact, a research titled “Effect of Uncorrected Astigmatism on Vision” concluded that astigmatism as little as 1.00 diopters can cause a significant reduction on a person’s quality of life. There are other factors to consider and one of the things to look out for is what is the level of your current astigmatism.

What are the levels of astigmatism?
There are 4 levels of astigmatism: Normal (<0.6 Diopters), Mild Astigmatism (0.6-2.0 Diopters), Moderate Astigmatism (2.0-4.0 Diopters) and Severe Astigmatism (>4.0 Diopters). All of which corresponds to the level or distortion in the images seen or can also be the degree of discomfort one can have in astigmatism.
This is a visual representation of what a person with astigmatism can see. As you can see, people with astigmatism tend to see a doubling of an image or text which makes is uncomfortable to look at, causing numerous symptoms of astigmatism such as headaches and dizziness.
At what level of astigmatism should you really wear glasses?
Once you reach the mild level of astigmatism, it is time to think about wearing glasses. Mild astigmatism are in the level of 0.6 Diopters and above. This level may now cause some discomforts such as difficulty reading texts, headaches and dizziness.
However, that is not the whole picture, there is no correlation between glasses and increasing or decreasing astigmatism. As proven by a research paper titled: “Reduction of Astigmatism after Infancy in Children Who Did and Did Not Wear Glasses and Have Strabismus.”.
So if you decided not to wear glasses, then it is completely up to you. The only thing to look out for is if it affects your quality of life such as your work or you are experiencing discomforts because of under correction.

Is my eyesight bad?
Here is a table summary showing the various levels of astigmatism categorized into its diopter equivalent. With this table, you can know if your astigmatism is bad depending on what your reading is.
|Astigmatism in Diopters||Astigmatism in Diopters|
|0.6 – 2.0 Diopters||Mild Astigmatism|
|2.0 – 4.0 Diopters||Moderate Astigmatism|
|>4.0 Diopters||Severe Astigmatism|
In the table, you will see that less than 0.6 diopters is considered normal. In fact, around a third of the people in US alone have astigmatism as pointed out by a prevalence study in the Archives of Ophthalmology. But having a 0.6 diopter astigmatism is still considered normal since it doesn’t really affect much of the person’s quality of life.

Once you get to the level of mild astigmatism which is 0.6 or 0.75 above, it is the time to start consider wearing astigmatism lenses.
Should you really wear glasses at 0.75 prescription?
At 0.75 prescription, you are already considered as someone with mild astigmatism. This might involve a change in your quality of life so you must wear glasses if it is so. Also look out for discomforts such as headaches or dizziness due to your astigmatism.
But as said, if it does not affect your quality of life whatsoever, then you are free not to wear one. As said in the research paper, there is no significant correlation between glasses and astigmatism. So if you think your glasses will permanently cure your astigmatism or glasses will make it worse, then science has not yet proven this.
The 0.75 prescription is a common question since a lot of people start at this prescription. So it deserves to have a separate part in this article.
Furthermore, there are more things to consider if you would want to wear glasses or not.
