Resin lenses have obvious advantages, with lenses made of resin being lightweight and more comfortable to wear; resin lenses have strong impact resistance, are not fragile, and are safer; In addition, resin lenses have good transparency, are easy to reprocess to meet special needs, and are inexpensive, making them the mainstream lenses on the eyeglass mart.

What is the refractive index of a lens? The refractive index of the lens, for myopia discountglasses, under the same other parameters, the higher the refractive index of the lens, the thinner and lighter the edge thickness of the lens, and the lighter the weight.

The physical form of spherical lenses cannot achieve perfect focusing of light, resulting in increased aberrations and deformations, clear images, distorted field of view, narrow field of view, and other adverse phenomena.

The design of non-spherical lenses corrects images, solves problems such as distorted field of view, and makes the lenses lighter, thinner, and flatter. Moreover, it maintains excellent impact resistance.

The advantage of non-spherical lenses is that they are clearer, and non-spherical lenses that have undergone unique coating treatment have perfect visual performance, presenting clearer and more comfortable visual effects.

After wearing non-spherical lenses, you can hardly feel their presence. They help you lose weight for your eyes and enjoy the relaxation and casualness they bring you. The design of non-spherical surfaces is more natural, with less visual distortion and more realistic visual effects.

The current differentiation of lenses in the eyeglass mart is based on the above division. When choosing lenses, it is not only necessary to choose suitable materials, but also to choose lenses with non-spherical designs to achieve a more comfortable wearing experience.

Eyes are the windows to the soul, and we all need to take good care of them to have a brighter future!
