Choose lenses made of materials with high refractive index: this kind of lens has a stronger refractive index than ordinary lenses, so it can be made thinner. The surface of high refractive index lens has strong reflection, so it is easy to use the lens with anti reflection coating. Choose aspheric lens: this kind of lens is thinner than that of spherical lens at the same degree, with light weight and less optical deformation.
Do not use rimless spectacle Glasses Frames For Women: because the edges of these Glases Women are not wrapped by frames, it is easy to see the thicker lens edges from the side. At the same time, they are not surrounded by Eye Glass Frames, and the height of the lenses is unstable.
Choose resin lens: for most patients, it is better to choose resin lens, because the weight of plastic lens is only half that of Womens Eyeglasses lens, with good anti ultraviolet function, not easy to break and easy to dye. Choose polycarbonate lenses: these lenses are not easy to break and are especially suitable for children and athletes. Patients with myopia wear polycarbonate lenses with a diopter above -7.00, and there may be scattered color lines when looking at the light through the periphery of the lens.
