preparation example Construction

[0044] The present invention also provides a method for preparing a novel driving lens. The steps are as follows:

[0045] 1. Obtaining the substrate:

[0046] a. Use rubber ring (or tape) and glass mold to close the mold, add IPP initiator, ultraviolet absorber, melanin solution in a certain proportion to the allyl diethylene glycol carbonate monomer, stir to prepare, and pour until it has been combined In a good glass mold, after 20 hours of non-linear curve curing, the glass mold and the preliminary formed lens are separated, and the substrate (1) is obtained after cleaning and secondary curing; test and adjust the content of melanin and ultraviolet absorber to meet the following conditions :T550 (transmittance of visible light with wavelength of 550nm and greater than 550nm, the same below) of the substrate should be greater than 85%, T450 (transmittance of wavelength 450nm, the same below)) should be less than 75%, Tsb (380nm~500nm blue light transmittance) Excess rate) shoul...

Embodiment 1

[0065] Example 1: C39 new driving lens

[0066] 1. Using EVA rubber ring and 500-bend glass mold to close the mold, add allyl diethylene glycol carbonate monomer IPP 84.2 parts, initiator IPP 2.8 parts, UV absorber 6 parts, and melanin solution 7 parts according to the following proportions. , Mixing and preparing, pouring into the already closed glass mold, after 20 hours of non-linear heating and curing, separating the glass mold and the preliminary formed lens, cleaning and secondary curing to obtain the substrate (1-1).

[0067] 2. Prepare the basic dyeing solution with OMS BLUEBLOCKER dyeing solution as the main material, and then heat the dyeing solution to a constant temperature of 92~95 degrees, first clean the substrate (1-1), and put all of the substrate into the color tank. Single color, control the dyeing temperature at 90-95 degrees Celsius, control the dyeing time for about 10 minutes, adjust the color solution concentration, temperature and time to obtain the substra...

Embodiment 2

[0078] Example 2: PC new driving lens

[0079] 1. Select optical grade PC raw material, mix with UV absorber, and obtain the unhardened lens through injection molding to obtain the substrate (2-1), test and adjust the content of UV absorber to meet the following conditions: T550( The transmittance of visible light with a wavelength of 550nm and greater than 550nm, the same below) should be greater than 85%, and Tuv (ultraviolet (UVA\UVB and UVC transmittance, the same below)) should not be greater than 2%.

[0080] 2. Prepare the basic dyeing solution with OMS's BLUEBLOCKER dyeing solution as the main material, and then heat the dyeing solution to a constant temperature of 92~95 degrees, first clean the substrate (2-1), and put all of the substrate into the color tank. Monochromatic, get the substrate (2-2), control the dyeing temperature at 90-95 degrees Celsius, control the dyeing time to be greater than 5 minutes, adjust the concentration, temperature and time of the color solut...

Abstract

The invention discloses a novel driving lens. A purpose of alleviating the irritation of sunlight and ultraviolet rays at daytime and improving the light sensation and blocking the high light in the opposite direction at night and in the dim light environment can be achieved. By adopting the driving lens, on the premise of guaranteeing the resolution of a signal lamp, an effect for enhancing the dim light, inhibiting the high light, clarifying the sight and facilitating the brightness and comfort in the middle-near distance can be achieved; the control is carried out by virtue of wavelength transmittance in the manufacture process, so that the range of the visible light wavelength is narrowed relatively, and more clarity of an object contour can be realized to a certain extent; meanwhile, a plating film is specially designed in the manufacture process, the radiation harm of an electromagnetic device inside a car for eyes of people can be alleviated, and the direct harm of ultraviolet rays and blue light and the indirect harm of the ultraviolet rays and blue light on the eyes of people by virtue of secondary reflection of the skin and lens can be alleviated.

Description

Technical field [0001] The invention relates to a spectacle lens and a manufacturing method thereof, and more specifically to a novel driving lens and a manufacturing method thereof based on different viewing distances and different wavelength transmittance control. Background technique [0002] With the improvement of people's living standards, motor vehicles are widely used as a means of transportation. The strong outdoor sunlight, especially the opposite glare in the low-light environment at night, causes great discomfort for the driver. Among them, the momentary inadaptability of the opposite glare at night is one of the main reasons for traffic accidents. [0003] Ordinary sunglasses including polarizers can filter out ultraviolet rays and block strong light. Daytime driving has a better protective effect on the driver. However, at night, haze, and rainy weather, the light transmittance is too low, which affects normal use. In addition, automobile films are becoming more and...
