Technical Field
The utility model relates to the technical field of defocusing lenses, in particular to an ophthalmic defocusing lens capable of correcting amblyopia and frame glasses with the same.
Background
What is defocus: it is meant that the focal point formed by the parallel rays of light after passing through the refractive medium does not fall on the retina. If the focal point is in front of the retina, what we say as myopia at ordinary times, this defocus state we call it myopic defocus (or positive defocus); instead, the focal point falls behind the retina, corresponding to the far vision state, and this defocus is called far vision defocus (or negative defocus).
In the process of myopia formation and development of children and teenagers, the macula fovea of a myopic patient presents myopia defocus (positive defocus), and the periphery of the macula fovea presents hyperopia defocus (negative defocus). Retinal hyperopic defocus is the most prominent cause of increasing power.
Why dynamic defocus intervention is to be performed: the curvature and refractive power of the cornea of the human eye in the horizontal direction and the vertical direction are different, the distribution of the defocus state of the retina of the human eye is also different, and the myopia degree of the human eye is also different and is divided into low myopia, medium myopia and high myopia, so that the dynamic defocus intervention is required to be implemented according to the degree of the myopia of the human eye and the distribution of the defocus state of the retina of the human eye.
Thus, in patients with myopia or hyperopia, defocused lenses are required for rehabilitation.
In view of the above-mentioned drawbacks, the present inventors have actively studied and innovated to create an ophthalmic defocus lens capable of correcting amblyopia and a frame glasses having the same, which are more industrially useful.
