Glasses with prisms
To correct violations in binocular vision, special prismatic glasses from strabismus will help. They are indicated for the treatment of children and adults and give a high efficiency of therapy. Prisms are made to order for a specific patient. Ochi Optics specialists will help you choose the right prismatic correction. Please note that the treatment of strabismus or binocular vision disorders is more effective in combination with hardware treatment methods. In the CENTER OF THERAPY & VISION TRAINING "OCHI"experienced ophthalmologists have experience in the hardware treatment of these visual impairments and will help you choose the best solution.
Indications for wearing and types of glasses
Specialized glasses for strabismus are indicated when the patient has double vision if he looks with two eyes. The disorder may be congenital or acquired as a result of trauma or appear as a complication after an unsuccessful operation to eliminate myopia. Binocular vision disorders occur in children and adults. Diplopia and strabismus cause great discomfort. The selection of prismatic glasses can partially or completely cure an eye with impaired muscle function. There are the following types:
- with purely prismatic glasses;
- blue-red light filters;
- Fresnel prisms;
- Sidorenko lenses with color stimulation.
All types of lenses correct image defects and eliminate discomfort, but they are unable to hide the unaesthetic appearance of eyes with strabismus, especially with large deviations. With the help of contact lenses, the disease is treated only if the eye "walks" due to farsightedness. Strabismus-concealing lenses continue to be developed by ophthalmologists, but so far without success. So far, the best proposal for aesthetics are glasses with an engraved eye on the inside.
To correct strabismus in adults and children, glasses with Fresnel prisms are widely used, the principle of operation of which is based on the property of prisms to deflect the light flux towards the base. This method is used to treat vertical heterotropia, used to correct convergent and divergent childhood strabismus. Fresnel lenses have a very wide scope, and aesthetic appearance - they are thin.
Application in ophthalmology
Specialized glasses for the treatment of strabismus are a common method of correction. Wearing them is mandatory for heterophoria, when the patient has severe headaches and discomfort from a distorted picture is expressed in rapid eye fatigue. In lenses for the elimination of visual defects, the base of the prismatic element is directed in the opposite direction from the displacement of the center of the visual organ. A different angle of inclination allows you to adjust the luminous flux and, accordingly, the picture of the surrounding world, removing ghosting and fuzzy contours. Prismatic lenses correct children's and adult strabismus. They are appointed in the following cases:
With the help of glasses with Fresnel lenses, vision is corrected in children who suffer from strabismus.
- to restore binocular vision;
- minimization or complete elimination of diplopia with partial or complete paralysis of the eye muscles;
- activation of the work of the eye muscles in heterophoria.
Is Prismatic Treatment Effective?
Glasses for the correction of strabismus have been practiced in ophthalmology for a long time and their effectiveness depends on both the diagnosis and concomitant active therapy. The systematic performance by the patient of eye gymnastics to strengthen the muscles of the organ of vision increases the effectiveness of prismatic glasses. Help eliminate strabismus exercises on a computer simulator - red-blue glasses. The combination of methods is guaranteed to minimize the acquired types of the disease.
Congenital childhood strabismus, which is based on binocular vision disorders, is difficult to treat. The success of therapy for children depends not only on the correct selection of lenses, but also on the conscientiousness of their wearing by the child. Constant work on yourself and observance of occlusion increases the chances of a cure. Therapy of the disease lasts for years. All the time, the patient is obliged to visit the doctor regularly and update the glasses in a timely manner according to the correction of the diagnosis.
