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 in children is caused by what?

The majority of astigmatism in children is caused by congenital factors, that is, genetic factors. If one or both parents of the child have astigmatism, the probability of the child having astigmatism is higher than that of other children. There are also a few cases where a child's astigmatism is caused by acquired factors, such as surgery, trauma, or illness, all of which may cause changes in the curvature of the cornea and lens. Additionally, a lack of outdoor activities and poor eye habits might also promote the development of astigmatism. It is recommended that once a child is diagnosed with astigmatism, they should go to a reputable hospital for examination and then get appropriate treatment to improve the condition, otherwise, it could impact their vision.

Can you wear contact lenses with 200 degrees of astigmatism?

Astigmatism of 200 degrees or less can be corrected by wearing regular contact lenses. However, when purchasing lenses, one needs to divide the astigmatism diopter by two and incorporate it into the prescription for myopia during the fitting process. If a patient's astigmatism exceeds 200 degrees, they typically are not suitable for regular contact lenses. Instead, they may opt for custom contact lenses with astigmatism correction or use rigid corneal contact lenses for correction. Patients with astigmatism should promptly visit an ophthalmology department at a hospital for an optometry examination to accurately determine their astigmatism and undergo vision correction tests. Following this, a doctor will issue a prescription for fitting contact lenses.

Can nearsightedness surgery correct astigmatism?

Surgery for nearsightedness can correct astigmatism, and surgeries for nearsightedness can be divided into corneal laser surgery and ICL surgery. Corneal laser surgery can be considered if the astigmatism is less than 400 degrees, while ICL surgery can be considered if the corneal astigmatism is less than 600 degrees. Additionally, astigmatism can be classified as regular and irregular. The treatment is generally more effective for regular astigmatism. If it is irregular astigmatism, further ophthalmologic examination should be conducted to rule out corneal and other ocular conditions.

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.

Will nearsightedness and astigmatism lead to blindness?

Myopia and astigmatism are common eye diseases and belong to two types of refractive errors, which can occur together. Myopia combined with astigmatism can lead to a decrease in vision, but it will not cause blindness. For patients with myopia and astigmatism, there are various methods to correct and treat these conditions, such as wearing frame glasses, rigid corneal contact lenses, undergoing laser surgery, or implanting artificial lenses to restore vision. In daily life, it is also important to develop good eye habits, avoiding using eyes in dim and shaking environments, and reducing the time spent on smartphones, TVs, and computers to prevent and delay the progression of myopia and astigmatism.
