Product Description:The surface curvature of the aspherical lens is different from that of the ordinary spherical lens. In order to pursue the thinness of the lens, it is necessary to change the curved surface of the lens. In the past, the spherical design was used, which increased the aberration and deformation. Small and other undesirable phenomena. The aspherical design now corrects the image, solves problems such as distortion of the field of view, and at the same time, makes the lens lighter, thinner and flatter. Moreover, excellent impact resistance is still maintained, making it safe for the wearer to use.
In traditional spherical lenses, objects around the lens are distorted, which limits the wearer's field of vision. In the era of continuous technological advancement, the optical miracle of aspherical design minimizes the edge aberration of the lens, making it wider Vision can meet the needs of customers. The base curve of aspherical lenses is flatter, lighter in weight, and looks more natural and beautiful. In the case of high diopter, the deformation of the eyes can be reduced. For consumers with high visual acuity, it may be more suitable to choose aspherical lenses.
The surface curvature of aspherical lenses is designed with aspherical surfaces. The advantages of this design compared to spherical design lenses are:
1) Clearer: The aspherical lens with unique coating treatment has a perfect visual performance, showing a clearer and more comfortable visual effect.
2) Easier: After wearing the aspherical lens, you can hardly feel its existence, it will lose weight for your eyes, enjoy the ease and casualness it brings to you.
3) More natural: aspherical design, more natural, less visual distortion, more realistic visual objects.
Purpose and advantages of aspheric lens design:
1. Purpose: In order to reduce the aberration of the optical correction lens, make the lens flatter, and reduce the magnification of the lens. Get clearer, thinner, lighter premium lenses.
2. Advantages:
1) Optical advantages: the aberration of the lens is reduced, and the vision is clearer.
2) High luminosity can also obtain a clear image: Although the spherical point focus lens is designed with the best base arc, the luminosity beyond +7.00D-22.00D is not within the range of the Cherning ellipse and cannot eliminate aberrations. Comparable image quality can only be obtained with an aspherical design.
3) The lens can be made flatter, thinner and more beautiful. The higher the mirror power of the spherical lens, the worse the appearance. Aspherical lenses can be designed with a relatively flat base arc, which not only makes the appearance beautiful, but also reduces the peripheral magnification. Make others look at the eyes of the wearer without much change in size.
