Parents often ask: “Since astigmatism is something that children are born with, can we not wear glasses? “Definitely not”! Why? Let’s take a look at “astigmatism”. What is astigmatism? Astigmatism is a condition in which the refractive power of the eye is different at different meridians, resulting in two focal lines that prevent the light entering the eye from forming a clear focus on the retina. What are the dangers of astigmatism without glasses? 1. poor vision, and the greater the astigmatism, the greater the impact on vision; 2. easy to cause amblyopia. Because astigmatism is blurred, if not corrected in time, it will affect the child’s visual development and lead to the formation of amblyopia; 3, visual fatigue. Astigmatism causes the blurred image to be perceived by the visual center, so the visual center will start the compensatory mechanism of “adjustment” of the human eye, trying to achieve the purpose of “focusing” to see clearly by changing the tension of the ciliary muscle and the thickness of the lens. However, there is a limit to the amount of regulation, and the eye should normally call for the right amount of regulation based on the distance and size of the target. If you use the adjustment inappropriately, over time it will make the adjustment disorder, thus producing visual fatigue. 4, accelerate the progress of myopia. Due to excessive regulation, regulation disorder caused by visual fatigue will accelerate the progress of myopia. Therefore, it is very important to wear astigmatism glasses in time to improve your child’s vision, avoid amblyopia, relieve visual fatigue, and slow down the development of myopia.
