Consequences of not wearing glasses for astigmatism

Astigmatism, like myopia, is also a type of personal vision problem. Astigmatism is more troublesome than myopia. Its main characteristic is that after astigmatism occurs, not only can distant objects not be seen clearly, but also double images will occur. After having astigmatism, you should wear glasses just like myopia to prevent the degree of myopia from further worsening. However, when fitting astigmatism glasses, you need to know the exact value before you can get the right glasses.

Main symptoms of astigmatism

The main symptoms of astigmatism are similar to those of myopia and hyperopia, which will cause the eyes to be unclear when looking at close objects or distant objects, and the clarity of lines is different. The habit of squinting and torticollis caused by astigmatism can easily lead to eye fatigue, temporary blurred vision, forehead headache, and poor vision in dim light and at night. Therefore, the symptoms of astigmatism should be taken seriously by everyone, and we should go to a regular optometry place to have professionals use appropriate methods to correct astigmatism, so as to effectively solve the impact of astigmatism on visual quality.

Astigmatism Key Principles

1. Generally, astigmatism within 50 is physiological, which is also called "regular astigmatism". Astigmatism in this case usually does not require glasses to correct after examination by a professional doctor.

2. Regardless of whether the astigmatism is low or high, it needs to be treated in time, otherwise it will bring new refractive errors to the child, which will affect the visual interference symptoms and make the vision more and more blurred.

3. Astigmatism below 300 degrees is also called "conformal myopic astigmatism". Children, adolescents or those with exotropia should be fully corrected, otherwise it will affect the health of the eyes or cause vision loss. At this time, you can wear glasses with astigmatism, which can effectively reduce the degree of astigmatism.

4. Wearing astigmatism glasses will cause discomfort in the early stages, and sometimes visual distortion and spatial errors may occur. You must be patient and insist on wearing them for a period of time to adapt. Do not put the glasses away for a long time when you feel uncomfortable, otherwise they will not have a corrective effect.

5. For children with astigmatism, teenagers and minors, when wearing astigmatism glasses, they must be fitted with sufficient degrees of astigmatism. This not only makes it comfortable to wear and reduces eyestrain, but also prevents and treats symptoms such as amblyopia and strabismus.

The refractive power of the eyeball is different on different meridians, forming two focal lines, which makes it impossible for the light entering the eye to form a clear focus on the retina, which is called astigmatism. If you don’t wear glasses, astigmatism will cause the following harm:

1. Poor vision, and the greater the astigmatism, the greater the impact on vision.

2. It can easily lead to amblyopia. Since astigmatism makes both near and far vision blurry, if it is not corrected in time, it will affect the child's visual development and cause amblyopia.

3. Visual fatigue. The blurred image caused by astigmatism is perceived by the visual center, which then activates the compensatory mechanism of eye adjustment, trying to achieve the purpose of focusing and seeing clearly by changing the tension of the ciliary muscle and the thickness of the lens. However, the ability to accommodate is limited, and under normal circumstances the eyes should use appropriate accommodation power according to the distance and size of the target. If you keep making inappropriate adjustments, the adjustments will become disordered over time, leading to visual fatigue.

4. Accelerate the progression of myopia. Visual fatigue caused by excessive or disordered accommodation will accelerate the progression of myopia.

Therefore, wearing astigmatism glasses in time is very important for improving children's vision, avoiding amblyopia, relieving visual fatigue, and delaying the development of myopia.
