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 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.

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 astigmatism wear orthokeratology lenses?

Astigmatism below 300 degrees generally can be corrected with orthokeratology (OK) lenses. Astigmatism is a type of refractive error where the eye has different refractive powers in different meridians, causing parallel light rays passing through the eye's refractive system to refract improperly and form two focal lines instead of a single focal point on the retina, resulting in a blurred image. Astigmatism can be categorized into regular astigmatism and irregular astigmatism. Regular astigmatism can be corrected using cylindrical lenses or glasses, while irregular astigmatism may require correction with corneal contact lenses, OK lenses, or surgical correction. Common symptoms of astigmatism include blurred vision, reduced visual acuity, and easy eye fatigue, and sometimes may also present with symptoms such as head tilting and headaches. Therefore, it is advisable to seek consultation in the ophthalmology refractive department if astigmatism symptoms appear.

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.
