It is not recommended to use cellphones every day during pregnancy. Although using mobile phones does not cause astigmatism, it can still harm the eyes of pregnant women.

Astigmatism is caused by congenital changes in the corneal shape and the intrinsic refractive state of the lens. Various acquired factors can also affect the outcome of astigmatism, such as unhealthy visual habits in daily life and changes in refractive status, which can lead to acquired astigmatism. Engaging in prolonged mobile phone use during pregnancy might lead to myopia, but it will not cause astigmatism. Long-term accumulation of myopia can lead to symptoms like dizziness and fatigue.

Astigmatism refers to a type of refractive error in which the eye does not focus light evenly onto the retina, often due to an irregular shape of the cornea or lens.

Astigmatism is a type of refractive error. Because our eyes are not a perfect sphere, they are more like an egg shape, with different meridians having different refractive powers. Thus, after imaging, the axial images may form in front of or behind the retina, rather than forming a focal point on the retina. Normally, astigmatism of some small degrees and with good axial alignment may not significantly affect vision. However, high degrees of astigmatism, especially irregular astigmatism, will definitely impact visual quality and require the prescription of special lenses to correct the astigmatism.

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.

Are there any treatments for high myopia and high astigmatism?

High myopia combined with high astigmatism can be treated in the following ways: First, correction by wearing frame glasses is the most widely adopted treatment method currently, which is affordable and safe. Second, using rigid corneal contact lenses for correction, which provide higher image quality than regular frame glasses. Third, correction can be done through laser surgery, such as excimer laser surgery, femtosecond laser surgery, and full femtosecond laser surgery, but it is only suitable for adult patients. Fourth, correction can be accomplished by implanting phakic intraocular lenses in the posterior chamber, generally suitable for patients whose corneal condition does not permit laser surgery, at a higher cost compared to laser surgery.

Can farsightedness and astigmatism be corrected with glasses?

Hyperopia is a condition where parallel rays of light entering the eye focus behind the retina, preventing external objects from forming a clear image on the retina. This condition is referred to as hyperopia. Astigmatism is due to the cornea of the eye having a certain curvature, with light bending unevenly across the cornea due to its irregular curvature, causing different refractive indices on each meridian of the cornea. This results in the light rays not focusing on the same focal point, thereby preventing the rays from accurately focusing on the retina to form a clear image. This condition is known as astigmatism. Both hyperopia and astigmatism are types of refractive errors, and wearing glasses can correct them. It is also necessary to wear glasses promptly for correction.

Can children with astigmatism undergo laser surgery?

Firstly, laser surgery is generally performed after the age of 18, as people's eyes continue to grow. This means that just like when a person stops growing taller, the eyes also stop growing at a certain age. If laser surgery is performed too early, while the eyes are still growing, the results may regress over time. Therefore, astigmatism in children should only be addressed after they reach adulthood, usually after the age of 18, but we generally recommend waiting until after the age of 21. Additionally, if the progression of the eye prescription is less than 50 to 100 degrees per year, the surgery outcomes are more likely to be stable. Generally, laser surgery is primarily used for myopia, which pertains to issues with seeing distant scenes, whereas astigmatism, which generally affects horizontal vision, is usually not corrected through laser surgery.
