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.

Do you need to wear glasses long-term if you have more than 200 degrees of astigmatism?

Patients with astigmatism of more than 200 degrees generally need to wear glasses long-term. Astigmatism of over 200 degrees is considered moderate and can significantly affect vision. If glasses are not worn to correct this, the patient's unaided vision is usually poor, causing blurriness and inconvenience in work and daily life. Additionally, prolonged unclear vision can easily lead to eye strain, and may even cause symptoms such as eye soreness, dizziness, and headaches. Astigmatism can be diagnosed through an optometric examination, which will determine the specific degree of astigmatism and its axis. Glasses can then be prescribed to correct it. If the patient is an adult who does not wish to wear glasses, laser surgery or the implantation of a posterior chamber intraocular lens can also be considered as treatment options.

Will astigmatism cause the pupils to enlarge?

Astigmatism of the eye is a type of refractive error caused by an uneven curvature of the cornea's surface, resulting in different refractive powers along different axes. Once astigmatism occurs, particularly with a high degree of astigmatism, there can be a noticeable decrease in vision, distortion in sight, or in severe cases, significant eye fatigue. However, it generally does not lead to pupil dilation. Pupil dilation is caused by the paralysis of the ciliary muscle due to internal and external factors, resulting in enlarged pupils. Therefore, if symptoms of astigmatism appear, it is advisable to visit a hospital promptly for accurate diagnosis and appropriate treatment.

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.

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.

Can nearsightedness with astigmatism undergo laser surgery?

Myopia and astigmatism are common eye diseases that are two different types of refractive errors but often occur together. Patients with both myopia and astigmatism who are over 18 years old and have stable prescriptions for more than a year can undergo laser surgery treatment. During the laser surgery, both myopia and astigmatism can be corrected simultaneously. Before undergoing surgery, patients need to visit the ophthalmology department of a hospital for an in-person consultation and examination. The exact degrees of myopia and astigmatism are determined through refraction tests, while corneal topography and ophthalmic ultrasound are used to assess the corneal curvature and thickness to determine if the patient is suitable for corrective laser surgery.
