How to choose glasses for high myopia?
How to choose the right lenses for high myopia? Too thick lenses will affect the appearance. How to make your eyes look more individual and comfortable after wearing glasses? Here are some ways to choose lenses for high myopia.
Of course, the lenses should be thinner, so you need to choose lenses with a high refractive index, so that they can be thinner. The frames should be relatively smaller, so that the whole pair of glasses looks more beautiful.
The lenses for correcting high myopia have a high degree, and are thick around the edges and thin in the center. There are several ways to reduce the thickness of the lens around the edges:
(1) Choose a smaller frame: A large frame not only increases the thickness around the lens, but also increases the weight of the lens.
(2) Choose lenses made of materials with a high refractive index: The refractive index of this lens is stronger than that of ordinary lenses, so it can be made thinner.
The surface of high refractive index lenses has a strong reflection, so it is better to use lenses with anti-reflective coating.
(3) Choose aspherical lenses: This type of lens is thinner than spherical lenses with the same degree, lighter in weight, and has less optical deformation.
