  • Astigmatism - what is it

    Astigmatism - a pathology of refraction of the eye atwhich violated sphericity cornea, ie, in different meridians of different refractive power and the image of the object with the light rays passing through the cornea so it turns out not as a point and a line segment. Man sees in this distortion of objects in which some lines are clear, others - blurred. Congenital astigmatism up to 0.5 diopters occurs in most people, and refers to the "functional", which has virtually no effect on visual acuity. However, as practice shows, the astigmatism in the 1 diopter or more lowers the vision and impairs visual comfort. This kind of pathology is detected in approximately 10% of cases among 25% of children with all types of amitropy. Such patients with astigmatism require an earlier vision correction using cylindrical (spherocylindrical) points. This is the primary prevention of amblyopia, strabismus and visual discomfort.

    Astigmatism - objects distorted image, some lines are clear, others are blurred.


    Astigmatism - the reasons and timing of occurrence

    Astigmatism - Treatment of astigmatismCauses of astigmatism is not fullystudied. In most cases, astigmatism is congenital and inherited character, revealed in childhood. However, the reason can be astigmatism surgery or eye injury. Image objects with astigmatism fuzzy, sometimes blurred, straight lines appear curved. Additionally defects of vision, astigmatism is usually accompanied rapid fatigue the eye, reduced vision, headaches.

    It is important: If a family has a sick astigmatism -the child should always be examined by an ophthalmologist. Astigmatism is only revealed in full ophthalmologic examination. Sam astigmatism patient feels a decrease in visual acuity. To correctly determine the degree of astigmatism, and especially its axes, you need a thorough examination of the computer. Even a small error in the diagnosis may lead to complete or intolerances glasses lenses as well as eyesight.


    Conservative treatment of astigmatism

    Early diagnosis of astigmatism - Complete ophthalmic examination, including computer research axes of the eyes.

    Proper vision correction - With the help of special glasses with cylindrical lenses or special contact lenses (toric lenses) selected by an ophthalmologist.

    Train myshsch - Responsible for the accommodation of the eyes (laserstimulation, video computer vision correction, instillation of drugs, special courses ocular gymnastics) - under the supervision of an ophthalmologist.

    restorative measures - Swimming, neck massage, douches, etc. on the recommendation of an ophthalmologist.

    Good nutrition - Balanced in protein, vitamins and trace elements such as Zn, Mn, Cu, Cr and others.


    Modern methods of correction of astigmatism

    Currently, there are three recognized astigmatism method, namely:

    spectacles - The most common method of correctionastigmatism, especially in children. When the astigmatism is used with special glasses cylindrical lens - positive or negative - depending on the type of astigmatism. For all its merits, glasses delivered to its owner a lot of inconvenience - constantly dirty, misted, slip and fall, preventing sports and any other physical activity. Glasses do not provide 100% vision correction. Points substantially restrict peripheral vision, violate stereoscopic effect and spatial perception, which is especially important for drivers. In case of accident or fall shattered glass lenses can cause serious injury. In addition, incorrect glasses may cause eye fatigue and the constant progression of astigmatism. However, the glasses, and today remains the most simple, cheap and safe method for the correction of astigmatism.

    Contact lenses - Contact lenses are used for correctionastigmatism small extent (3 diopters). toric lenses, which should pick up an ophthalmologist - When astigmatism special uses. Toric lenses are peculiar to all the limitations and disadvantages, as well as other types of contact lenses.

    Laser correction of astigmatism - For adults (over 18 years) witha stable form of astigmatism modern ophthalmology offers the most advanced method of correction - laser correction of astigmatism. The best laser vision correction technology today with astigmatism is LASIK - operation guaranteeing patient with astigmatism normal vision, without any restrictions.


    Prevention of astigmatism

    light mode - Visual load only in good light, with the top light table lamp 60-100 W, use fluorescent lights.

    Mode of visual and physical activities - It is recommended to alternate visual stress to the active, moving the rest.

    Gymnastics for the eyes - 20-30 minute sessions are recommended exercises for the eyes.
