Abstract

Provided are training glasses, a training system, and a training method thereof. Each of the lenses includes a first refractive training area and a second refractive training area; the first refractive training area is an enclosed area at a center of each lens, and the second refractive training area is an area other than the first refractive training area of each lens, the second refractive training area has a diopter ranging from +1.0 D to +4.5 D. The training glasses and the training method of the present disclosure can provide a very uniform and stable peripheral diopter, and also avoid a significant change in diopters caused by a partition. Meanwhile, occurrence of a central diopter at the periphery is avoided, so as not to add adverse factors to the hyperopic defocus phenomenon of peripheral retinal, and the hyperopic defocus phenomenon of peripheral retinal can be effectively resisted.
