An astigmatism refers to more than one refraction in which the light in the eye is refracted from the cornea, causing the focus to fail to become one and have two or more points of focus.The precise diagnosis of astigmatism can be diagnosed by an ophthalmologist, but let's learn how to test astigmatism at home.

In fact, many people have some astigmatism, but not enough to affect their daily lives.However, severe symptoms can affect vision, especially if you leave someone with severe astigmatism when you are young, which can affect vision development and cause weak vision.

Astigmatism is often accompanied by myopia or perspective.The astigmatism is usually corrected by wearing glasses or lenses, but in case of irregular astigmatism, it is corrected using hard contact lenses.If the cone cornea is not calibrated due to a problem, corneal transplants can be performed.Since the astigmatism test in the text is for self-diagnosis, it is advisable to visit an ophthalmologist for accurate judgment.

five types of astigmatism test

Let me introduce you to 5 simple astigmatism tests at home.The tests below are not 100% accurate, so you should not be blind to them, and it is recommended that you have an accurate diagnosis from a specialist and start treatment.All tests must be carried out without glasses or lenses in use and at intervals of about 1 meter from the monitor.When you do an astigmatism test, you can test with the screen brightness adjusted not too bright or too dark.

Pikachu Test

If you see the Pikachu character from a distance of 1m, you may suspect astigmatism.

sentence test

If you see the sentence, 'If you see this letter now, you are astigmatism,' you may suspect astigmatism.

Line Thickness Test No. 1

If the thickness of all the lines is the same and they are not clearly visible, you may suspect astigmatism.

Line Bold Test No. 2

If the thickness and shape of all the lines are the same and do not look clear, you may suspect astigmatism.

Line Bold Test No. 3

If the thickness and color of the vertical and horizontal lines do not look the same, you may suspect astigmatism.

astigmatism symptom

In the case of mild astigmatism, there are no special symptoms, but if the symptoms are severe, trying to focus may cause eye fatigue, eye pain, and headaches.There are also visual impairments where objects or objects are not clearly visible.

• The object looks blurred.
• I can't see clearly from both close and far.
• I often frown to see clearly.

astigmatism complication

Most astigmatism does not significantly progress or change the degree of symptoms, but in some cases it can lead to ophthalmic anomalies.

astigmatism prevention method

As young as possible (age 3) astigmatism test and ophthalmic examination should be used to determine corneal abnormalities.If an abnormality in refraction is diagnosed, corrective glasses should be worn to prevent vision damage.The following situation is a shortcut to damage eye health, so you should avoid it.

• To work long hours in too dark a place
• Reading in a Shaking Car
• To work close range for a long time
• To wear glasses that do not fit the prescription

If an astigmatism is diagnosed, regular eye examinations should be performed to monitor for refractive abnormalities of the eyeball, which is the same for myopia and primitive.

treatment of astigmatism

The treatment of astigmatism is typically using glasses.However, you may feel dizzy when you suddenly wear astigmatism glasses when the astigmatism increases or the astigmatism axis of both eyes is different.Similar to glasses, contact lenses can be worn, but severe astigmatism with 2.0 to 2.5 deopters or more can be difficult to calibrate using contact lenses.

Other than glasses and lenses, there is refractive correction surgery and you can correct both astigmatism and myopia.In addition, surgical treatments such as corneal incision, plastic ring insertion, and lens implantation can be performed.

astigmatism and glasses

• Do I have to wear glasses for astigmatism?

It depends on the case, but if it is within 1.25 deopters, it may not affect vision without having to calibrate it through the glasses.Also, astigmatism and vision are not always proportional, so even if astigmatism is severe, there are times when vision is good, and there are times when astigmatism is not very good, but there are times when vision is bad.That is, even if you have astigmatism, you don't have to wear glasses if you don't have any problems such as special discomfort or impaired vision.

An astigmatism test in the text should be used for accurate diagnosis by an ophthalmologist if refraction abnormalities are suspected.If vision correction is required, sufficient consultation with a specialist can help determine the treatment direction.
