1, mild asymptomatic astigmatism does not require correction. 2, Symptomatic mild astigmatism, high astigmatism or visual impairment must be corrected with cylindrical lenses. 3.Irregular astigmatism can be corrected with corneal contact lenses. Astigmatism can be treated by surgical correction, depending on how many degrees, the average person’s astigmatism is not too high also do not need to consider, individual people with very high degrees can consider surgery to knock off! Most astigmatism can be corrected with glasses. Astigmatism can also be corrected with special contact lenses and refractive surgery, which have been developed recently. Astigmatism affects vision as much as nearsightedness and farsightedness, but astigmatism is much more complicated because it has problems in both refraction and orientation. In general, astigmatism is relatively stable and does not usually increase in magnitude with age. Therefore, mild astigmatism (within 50 degrees) does not require correction in general. However, those who are engaged in precision work or need to read small text for a long time can consider wearing glasses. For moderate to high astigmatism, hyperopic astigmatism or myopic astigmatism, glasses are often used for correction. In the early stage of conical cornea, when the corneal irregularity astigmatism is not obvious, frame glasses or general soft contact lenses can achieve better corrected vision. As the lesion progresses, when frame glasses or soft contact lenses cannot get satisfactory corrected vision, then rigid contact lenses can be used. However, if the cornea is cloudy or cracked due to corneal injury, it cannot be corrected. Therefore, it is important to protect the cornea. If astigmatism is found in children under six years of age, they should be examined early. If astigmatism is found during the vision screening, they should wear glasses for astigmatism as soon as possible. It is easy to confuse the disease and vomiting symptoms.
