What is astigmatism and what is its cause?
Why do I have astigmatism? Can I do something to prevent it? At what age is it usually detected? Is a special frame used for this visual need? You have the solution to these common questions in this simple post. But first of all, what is astigmatism?
Astigmatism is an irregularity in the curve of the eye that makes us see blurry both far and near. People with astigmatism are prone to eyestrain, eye discomfort, and headaches.
What are the causes of astigmatism?
This is because the cornea does not have a regular curvature and light focuses on various points on the retina.
At what age is astigmatism detected?
This visual abnormality is usually detected at a very early age. From 3-4 years, it can already be diagnosed in children's first visual check-ups. It is also usually detected early because the probability of suffering from it is hereditary, with which more emphasis is placed on these visual check-ups at an early age.
Astigmatism cannot be corrected, but we can reduce or compensate it by using prescription glasses or toric contact lenses such as Biofinity Toric monthly .
How to prevent astigmatism?
As previously discussed, astigmatism is a congenital disease. What does this mean? It means that you are born with it. The probability of developing it is hereditary. The importance of visual check-ups at an early age is decisive for a correct follow-up of the possible anomaly that does not lead to other diseases such as amblyopia or lazy eye. Normally it cannot be prevented, but with proper monitoring of our visual health and using preventive measures, we make sure not to exacerbate development and protect ourselves from future eye pathologies.
Types of lenses for astigmatism
In the case of astigmatism, the opposite happens to the myopic lens. Its crystal is convex, thick in the center and narrows as we approach the edges. Therefore, to avoid astigmatism, it is better to choose a frame with the largest lens.
