astigmatism is a common clinical disease, which occurs mostly in children and adolescents. It is divided into congenital and acquired. Among them, congenital factors are more common, mainly because the curvature of the cornea on each meridian is different or the lens position is deviated, or the retina Deflection, etc., cause the light to be unable to form a superimposed focus on the retina after the human eye is bent, but to form a blurred focal line. Clinically, it is mainly manifested as blurred vision in , double vision and so on.
Generally speaking, the corneal astigmatism check and the eye astigmatism check can be performed through a computer or professional equipment to determine whether there is astigmatism. After confirming that there is astigmatism, you need to determine the strength of the astigmatism. Generally speaking, you can use the astigmatism meter to get a preliminary understanding of the astigmatism.
From the perspective of types, astigmatism includes regular astigmatism and irregular astigmatism. Regular astigmatism mainly includes compliant astigmatism, oblique axis astigmatism, and anti-regular astigmatism . Because it is mostly congenital and there are problems with the visual structure, it is more difficult to treat. Irregular astigmatism is mostly caused by acquired factors, such as peripheral corneal degenerative disease, keratitis, polyps or keratoid tumors, cataract surgery, etc., which can be corrected by certain means.
Then there is astigmatism, what should we do?
1. Pay attention to eye care
Pay attention to eye care, focusing on not watching books and TV screens for a long time, taking a break every 40-60 minutes; looking into the distance if necessary. Look at some green plants and take some eye protection.
2. Eat more foods rich in vitamin A.
Everyone knows that vitamin A can effectively prevent night blindness and also has a better maintenance effect on vision. Therefore, you can eat more vitamin A-rich carrots, cod liver oil, etc., to maintain our Vision is in a good functional state.
3. Frequently perform eye massage.
often do eye exercises. You can use fumigation and other methods to properly care for your eyes. You can also perform eye massage frequently. By activating the blood circulation around the eyes, strengthen the blood supply to the eyes, and make our eyes healthier and brighter.
4. Wearing glasses or surgical treatment
First of all, if possible, children or adolescents can wear frame astigmatism lens correction, through certain correction and adaptation to improve the astigmatism of their own eyes. In addition, high oxygen permeability rigid contact lenses (RGP) can also be used to correct the astigmatism problem of the eye to achieve dual treatment of astigmatism and myopia. In addition to wearing glasses, if necessary, refractive error correction surgery, corneal laser surgery, intraocular lens surgery, etc. can also be used to improve astigmatism.
In summary, astigmatism is a common clinical symptom. Mild astigmatism can be corrected by optical correction or surgical treatment to help patients correct vision and relieve blurred vision, visual fatigue, double vision and other phenomena. Patients themselves should also strengthen eye care to better adapt to the needs of work and life.
