Abstract

Настоящее изобретение относится к устройствам для профилактики близорукости, используемым при чтении и письме, и содержит опору (1), первый плоский рефлектор (4), второй плоский рефлектор (11) и глазок (7), причём первый плоский рефлектор (4) отражает свет, исходящий непосредственно от объекта, расположенного в поле зрения, полная длина оптического пути S=S1+S2+S3 больше или равна 300 мм и меньше 5000 мм, а глазок снабжен линзой или набором линз. К преимуществам настоящего изобретения относятся широкое поле зрения, достаточная адаптивность при меньшей подверженности глаз усталости и естественности процессов чтения и письма, что позволяет продлить время работы или учебы, эффективно предотвращать и лечить близорукость и повышать лечебный эффект в соответствии с различной степенью близорукости у людей. Настоящее изобретение обеспечивает возможность регулировки расстояния наблюдения и угла зрения, удобство в использовании и возможность коррекции сидячего положения и предотвращения шейного синдрома. Изобретение особенно полезно для пользователей, практикующих чтение и письмо на малом расстоянии в течение длительного времени.The present invention relates to devices for the prevention of myopia, used in reading and writing, and includes a support (1), a first flat reflector (4), a second flat reflector (11) and a peephole (7), with the first flat reflector (4) reflecting light outgoing directly from an object located in the field of view, the total optical path length S = S1 + S2 + S3 is greater than or equal to 300 mm and less than 5000 mm, and the peephole is equipped with a lens or a set of lenses. The advantages of the present invention include a wide field of view, sufficient adaptability with less exposure to eye fatigue and natural reading and writing processes, which allows extending work or study time, effectively preventing and treating myopia and increasing the therapeutic effect in accordance with different degrees of myopia in people. The present invention provides the ability to adjust the viewing distance and angle of view, ease of use and the ability to correct a sitting position and prevent cervical syndrome. The invention is particularly useful for users practicing reading and writing at a short distance for a long time.
