Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of lens, concretely relates to a multi-optical power vision correction resin lens. BACKGROUND
[0002] As one of the reasons for causing myopia to deepen, the blur of hyperopia in the central part of the retina (the formation of a clear image behind the retina) can be listed, which is caused by the accommodation lag when looking at the near object (the lack of or relaxation of the lens accommodation force required for focusing on the near object, the lens accommodation). That is, it is a process as follows: the focal point of the central part of the retina is located behind the retina, causing the eye axis to be elongated to adapt to it, the eye becomes longer in the front-back direction, resulting in myopia deepening. Therefore, using glasses when looking at the near object gives the degree of auxiliary accommodation force, preventing the formation of a clear image behind the retina, which helps to inhibit myopia deepening. In order to inhibit myopia deepening, there is a view that not only the center of the retina needs to be considered, but also the imaging state of the peripheral part of the retina is important. The logic is that since the peripheral part of the retina is also elongated due to the blur of hyperopia, the peripheral part of the retina is also one of the reasons for causing myopia to deepen, therefore, by correcting with glasses, the focal point of the peripheral part of the retina is not imaged behind the retina, so that myopia deepening can be inhibited.
