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 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.

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.

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.

Can astigmatism and strabismus be corrected?

Astigmatism and strabismus can sometimes be corrected, depending on their severity. Astigmatism refers to the condition where parallel light rays entering the eye cannot focus on a single point on the retina after being refracted by the eye's optical system, instead forming two focal lines, ultimately failing to produce a clear image on the retina. Astigmatism can be categorized into regular and irregular types. Regular astigmatism can be corrected with cylindrical lenses in eyeglasses; while irregular astigmatism generally requires correction with contact lenses. Additionally, after reaching 18 years of age, astigmatism can also be corrected through refractive surgery. Generally, mild astigmatism does not impact vision and does not require special treatment; however, moderate to severe astigmatism, if uncorrected, might lead to amblyopia and other vision impairments. Strabismus means that when one eye is focusing, the visual axis of the other eye deviates from being parallel, presenting an abnormal eye position. It is generally recommended to start treatment immediately after diagnosing strabismus. If there is significant refractive error, glasses should be prescribed first. If glasses cannot correct the condition, surgery might be necessary.

Crystalline astigmatism is caused by what?

Lenticular astigmatism is a common eye disease, usually caused by the early formation of cataracts, where the lens becomes unevenly opaque. This leads to inconsistent refractive power in different directions, causing astigmatism. Patients can visit the ophthalmology department of a hospital for an optometry examination and a slit lamp microscope examination to confirm whether the astigmatism is due to the lens. For lenticular astigmatism, if the cataract has little impact on vision, it can initially be corrected by wearing glasses to improve vision. If the cataract has already significantly affected vision, cataract surgery can be performed to correct and treat it. After the surgery, the lenticular astigmatism will naturally disappear, and the patient’s vision will be improved.
