Astigmatism is a kind of common ametropia, which usually occurs together with myopia or hyperopia. In severe cases, it may cause visual fatigue,torticula, amblyopia and other adverse consequences.So,whether can astigmatism wear contact lens?
Astigmatism is a relatively common refractive error, usually with myopia or hyperopia, severe cases may cause astigmatism of course can wear contact lenses, and wearing contact lenses is a better way to correct.Contact lenses can significantly reduce the change rate of objects, whether nearsightedness, farsightedness or astigmatism, can achieve a clearer and truer correction effect than glasses.
However, astigmatism contact lenses are not mismatched, the first should be clear whether it is really necessary.When the astigmatism degree is less than 75 degrees, the majority of cases will not affect the visual objects, this kind of people do not need to be specially equipped with astigmatism contact lenses, ordinary contact lenses plus tear layer can meet the correction requirements.But if astigmatism is greater than 75 degrees, or has a greater impact on daily life, it is best to use astigmatism contact lenses for correction, so as not to continue to aggravate astigmatism.
Astigmatism contact lens matching glasses are very special, on the basis of ordinary contact lens matching glasses also involve the lens positioning problem.This is because astigmatism is caused by the fact that the light passing through the lens cannot form a unified focus, so in order to help the light focus, astigmatism lens must always maintain a stable position, can not follow the eye like ordinary lenses to ensure a clear field of vision.
Accordingly, if want to match astigmatism contact lens, must arrive regular hospital check-up match.And because each person's eye condition is not the same, only after checking fundus diseases and measuring the accurate degree, the ophthalmologist can give the most reasonable advice for matching glasses.
