Single optical glasses
Single-lens optical glasses are mainly used to correct vision, so that the wearer can see clearly. To a certain extent, it can help myopia patients to maintain clear vision when looking at a distance, reduce the adjustment fatigue caused by blurred vision of the eyes, and to a certain extent, it has a certain slowing effect on the rapid development of myopia. However, for people who are already myopic, monoclors can not fundamentally prevent the physiological process of myopia development such as the growth of the eye axis, and their role in myopia prevention and control is relatively limited.
Progressive multi-focus glasses
Progressive multifocal glasses have a number of different diopter regions on the same lens, generally the upper part is used to see far, the lower part is used to see near, and the middle part is the transition region. Its design principle is to alleviate eye fatigue by reducing the adjustment needs of the eyes when looking close, which can theoretically control the development of myopia to a certain extent. For some myopia caused by excessive adjustment caused by long-term close eye use, progressive multi-focus glasses may have a certain prevention and control effect. However, its actual effect varies from person to person, and some studies have shown that it has a certain effect on the prevention and control of myopia in children, but the effect is not very significant, and the wearer needs some time to adapt to the degree of change in different areas of the lens.
A plastic keratoscope
Orthokeratology lenses are special rigid, breathable contact lenses that are worn at night to reshape the cornea and change the curvature of the cornea, thereby temporarily reducing myopia and enabling clear vision without glasses during the day. A large number of studies and clinical practice have shown that orthokeratology has a significant effect on controlling the development of myopia, and can effectively slow down the growth of the eye axis, thus controlling the deepening of myopia degree. However, the orthokeratology lens needs to be worn and taken care of in strict accordance with the regulations, and is not suitable for all people, and the wearer needs to undergo a detailed eye examination and evaluation, while paying close attention to the health of the eye during the wearing process to prevent complications such as infection.
Specially designed soft contact lenses
Some specially designed soft contact lenses, such as peripheral defocusing contact lenses, make the peripheral retina image in front of or above the retina through special optical design, forming myopic defocusing, thereby inhibiting the growth of the eye axis and achieving the purpose of controlling myopia. The study found that this kind of contact lens has a certain effect on the prevention and control of myopia, and has shown in some clinical trials that it can effectively slow the progression of myopia, and it is relatively convenient to wear and comfortable. But equally, it also has a certain scope of application and wearing requirements, need to be selected and used under the guidance of a professional doctor.
Functional frame glasses
In recent years, some functional frame glasses with special optical design have appeared, such as multi-point myopia defocusing frame glasses. These glasses inhibit the growth of the axis of the eye by placing multiple microlenses on the lens or using a special optical structure that causes light to form an out-of-focus area in front of the retina. Clinical studies have shown that this kind of functional frame glasses have a certain effect in the prevention and control of myopia, can slow down the deepening of myopia degree to a certain extent, and provide a new choice for the prevention and control of myopia.
