Description

Strong anti-fog spectacle lenses and glasses

This creation is about a fitting for the human body, especially a strong anti-fog spectacle lens and glasses.

In addition to being used to correct myopia, glasses can also be used for a variety of purposes, such as sunglasses that block sunlight, frog mirrors that prevent water from entering the eye, or snow mirrors that avoid strong winds when skiing. In general, the more functions of glasses, the higher the added value, and the more popular with consumers. For example, frog mirrors and snow mirrors often use electroplating to make the glasses filter, in order to avoid water and snow reflecting a lot of sunlight. In addition, frog mirrors or snow mirrors are exposed to the water and temperature of the human body for a long time, and it is easy to fog due to the temperature difference with the outside world. Therefore, frog mirrors and snow mirrors often require additional anti-fog processing.

Referring to FIG. 1, an ophthalmic lens capable of simultaneous anti-fog filtering includes a first mirror 11 and a second mirror 12 spaced apart from each other, and a first mirror 11 and the second mirror 12 are disposed. An annular foam 13 and two layers of adhesive layer 14 for adhering the first mirror 11, the second mirror 12 and the annular foam 13. The first mirror 11 is subjected to an anti-fog treatment in advance to have an anti-fog effect. The second mirror material 12 is subjected to a plating treatment in advance to have a filtering effect. Between the first mirror 11 and the second mirror 12, fogging caused by excessive temperature difference can be avoided due to the heat insulating effect of the air. Although the double-layer lens structure can have both effects, the design will increase the overall weight, making the product cumbersome and causing discomfort to the user after wearing for a long time.

In order to solve the above problems, some manufacturers have adopted a single-layer lens substrate design, first spraying an anti-fog layer on a single-layer lens substrate by spraying, and then plating a filter layer on the anti-fog layer. However, in this method, the plating layer is not easily attached to the anti-fog layer uniformly, and even if it can adhere to the anti-fog layer, the quality is not good, resulting in poor anti-fog filtering effect and poor durability, which needs to be improved.

The first object of the present invention is to provide a strong anti-fog spectacle lens with better anti-fog effect and facilitate subsequent electroplating processing.

The strong anti-fog spectacle lens comprises a lens substrate and an anti-fog structure disposed on the lens substrate by immersion treatment. The lens substrate is in the form of a sheet and includes an opposite outer surface and an inner surface. The anti-fog structure includes two layers of anti-fog layers respectively disposed on the outer surface and the inner surface.

The effect of the strong anti-fog spectacle lens is that the anti-fog layer of the anti-fog structure is set by the immersion treatment, and can have a thicker thickness than the spray treatment, in addition to achieving the same anti-fog effect as the double-layer lens. In addition, the thicker and smoother anti-fog layers also facilitate subsequent plating processes.

The second object of the present invention is to provide a strong anti-fog glasses with better anti-fog effect and facilitate subsequent electroplating processing.

The powerful anti-fog glasses include a frame and at least one powerful anti-fog lens. The strong anti-fog ophthalmic lens is disposed on the frame and includes a lens substrate and an anti-fog structure that is immersed on the lens substrate. The lens substrate is in the form of a sheet and has an opposite outer surface and an inner surface. The anti-fog structure has two layers of anti-fog layers respectively disposed on the outer surface and the inner surface.

The effect of the strong anti-fog glasses is that the anti-fog layer of the anti-fog structure of the strong anti-fog lens is set by the immersion treatment, and can have a thick thickness compared with the spraying treatment, in addition to achieving double The same anti-fog effect of the layer lens can also replace the design structure of the existing double-layer lens, and the thick and smooth anti-fog layer is also beneficial for subsequent electroplating processing.
