Astigmatism should be corrected by wearing astigmatic lenses. Astigmatism is a type of refractive error where the refractive power of the eye varies along different axes, resulting in a refractive abnormality. Particularly with high degrees of astigmatism, there may be symptoms such as blurred vision, distorted vision, or even eye fatigue. Therefore, once astigmatism is detected, it is important to visit a hospital for a medical eye examination promptly. It is recommended that astigmatism of 50 to 75 degrees or more should be timely corrected with glasses, otherwise prolonged uncorrected astigmatism can lead to severe eye fatigue. Additionally, if adult patients have other refractive errors such as myopia along with astigmatism, they could also consider undergoing laser surgery for myopia correction.

What foods should be eaten for astigmatism?

For astigmatism, it is important in daily life to consume a diet rich in proteins, vitamins, and carotenes, such as meat, eggs, dairy, various fresh fruits and vegetables, and carrots. It is advisable to avoid spicy and irritating foods. If astigmatism occurs, it is important to visit a hospital for an optometric examination promptly. If there is significant astigmatism, it should be corrected with glasses based on a medical optometric examination, as uncorrected astigmatism can lead to severe eye strain over time.

Can high myopia with astigmatism be treated with surgery?

High myopia combined with astigmatism can also be treated surgically, but it requires the patient to be at least 18 years old, and both the myopia and astigmatism must have been stable for over a year without worsening. Before undergoing surgical treatment, a detailed eye examination is necessary. This includes an optometric examination to accurately measure the degree of myopia and astigmatism, a corneal topography test, and an ophthalmic ultrasound to understand the corneal curvature and thickness. Based on these parameters, a specific surgical plan is designed. If the patient’s corneal condition allows, laser surgery is the preferred method for correction. If the patient’s corneal condition is poor and not suitable for laser surgery, correction and treatment can be achieved through the implantation of a posterior chamber intraocular lens in phakic eyes.

How can children with minor astigmatism recover?

Mild astigmatism in children refers to astigmatism below 150 degrees, which can impact vision. Currently, once the degree of astigmatism is established, there are no effective non-surgical treatments available to reduce it. Since children cannot immediately undergo surgery to correct astigmatism, the alternative is to wear frame glasses or rigid corneal contact lenses to correct their vision and enhance their eyesight. In subsequent life, it's important to develop good eye habits, avoid squinting when looking at things, not use the eyes at close range for extended periods, and try to prevent the degree of astigmatism from increasing. After reaching adulthood, astigmatism can be corrected through laser surgery.

How to relieve headaches caused by astigmatism in the eyes?

Eyestrain and headache can be understood in two senses: First, if one experiences astigmatism when viewing objects, accompanied by headaches and eye pain, it is possible that glaucoma is present. This condition is also associated with increased eye pressure and swelling pain in the eyes. If this is the case, treatment to lower eye pressure and treat glaucoma is necessary. The second meaning involves astigmatism identified through an eye examination, indicating a refractive error. If the astigmatism correction in the glasses worn is not suitable, prolonged viewing can lead to visual fatigue, eye pain, and accompanying headaches. In this case, a detailed eye examination followed by wearing appropriate glasses is needed to alleviate the symptoms.

How to protect eyes with astigmatism

Some patients have congenital astigmatism, while most of the patients have acquired astigmatism. The occurrence of astigmatism is mostly due to improper sitting posture. It is caused by looking at objects from an inclined angle rather than directly from the eyes' proper axis. Especially lying down while reading or using smartphones can easily lead to an increase in astigmatism. If astigmatism is not corrected, it can easily worsen eye fatigue, thereby inducing a further increase in the degree of vision problems. In daily life, it is important to correct poor sitting postures and avoid situations such as lying down while reading or using smartphones. Engage more in outdoor activities, and limit reading sessions to no more than half an hour at a time. Consuming more vitamins A, D, C, E, and lutein in the diet can also help in preventing astigmatism.
