Problems solved by technology

[0004] At present, in the preparation process of this kind of frosted lens, it is often necessary to use adhesive materials such as glue to bond the frosted substrate and the smooth substrate to achieve the above effect, but the loss rate of this preparation method is high, and the bonding The use of materials also increases the cost and process. After a long time of use, it is easy to cause the glue to fail and cause the substrate to fall off.

Abstract

The invention belongs to the technical field of glasses lenses and particularly relates to a frosted lens and a preparation method thereof. The preparation method comprises the following steps: carrying out frosting treatment on the outer surface of a substrate, carrying out film plating on a frosted surface, carrying out ion gun spraying on a film plated surface and filling the film plated surface subjected to the ion gun spraying treatment. According to the frosted lens provided by the invention, tight and form combination of the frosted surface, a film plated layer and a filling layer of the substrate is successfully realized; and the ideal frosted effect of the lens is still kept.

Description

technical field [0001] The invention belongs to the technical field of spectacle lenses, in particular to a frosted lens and a preparation method thereof. Background technique [0002] People usually rely on adjusting the pupil size to adjust the luminous flux in the sun. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, it is necessary to use sunshade mirrors to block the sun, so as to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation. Today, the role of sunglasses is far more than just protecting the eyes, and it has become more and more a fashionable decoration and is accepted by consumers. [0003] Lens is the core of the quality of glasses. With the development of sunglasses technology, frosted lenses have appeared, that is, the outer surface of the lens substrate (the outer surface faces the object to be obse...
