preparation example Construction

[0043] The present invention also provides a kind of preparation method of driving lens, and its steps are as follows:

[0044] 1. Obtaining the substrate:

[0045] a. Use an apron (or adhesive tape) and a glass mold to close the mold, add IPP initiator, ultraviolet absorber, and melanin solution to the allyl diglycol carbonate monomer in a certain proportion, stir and 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; the content of melanin and UV absorber is tested and adjusted to meet the following conditions : The visible light transmittance of the substrate with a wavelength of 550nm should be greater than 85%, the transmittance of 450nm should be less than 75%, the transmittance of blue light with a wavelength of 380nm to 500nm should be less than 75%, ultraviolet UVA\UVB and UVC T...

Embodiment 1

[0065] Example 1: C39 Driving Lens

[0066] 1. Use the EVA rubber ring and the 500-curved glass mold to close the mold, and add 84.2 parts of allyl diglycol carbonate monomer IPP, 2.8 parts of initiator IPP, 6 parts of ultraviolet absorber, and 7 parts of melanin solution in the following proportions prepared by stirring, pouring into a glass mold that has already been assembled, and curing after 20 hours of non-linear heating, separating the glass mold and the preliminarily formed lens, cleaning and secondary curing to obtain the substrate (1-1).

[0067] 2. Prepare the basic dyeing solution with the blue light suppression dyeing solution of OMS as the main material, then warm the dyeing solution to a constant temperature of 92-95 degrees, first clean the substrate (1-1), and put all the substrates into the color tank. To dye a single color, control the dyeing temperature at 90-95 degrees Celsius, control the dyeing time for about 10 minutes, adjust the concentration, tempera...

Embodiment 2

[0077] Example 2: PC Driving Lens

[0078] 1. Select optical-grade PC raw materials, add UV absorbers, obtain unhardened lenses through injection molding, and obtain substrates (2-1). Test and adjust the content of UV absorbers to meet the following conditions: the wavelength of the substrates is The transmittance of visible light at 550nm should be greater than 85%, and the transmittance of ultraviolet UVA\UVB and UVC should not be greater than 2%.

[0079]2. Prepare the basic dyeing solution with the blue light suppression dyeing solution of OMS as the main material, then warm the dyeing solution to a constant temperature of 92-95 degrees, first clean the substrate (2-1), and put all the substrates into the color tank. Dye a single color to obtain 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 solution, so that the substrate is tran...

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, more specifically to a manufacturing method of a driving lens based on control of light transmittance of different viewing distances and different wavelengths. Background technique [0002] With the improvement of people's living standards, motor vehicles are widely used as a means of transportation. The strong sunlight outdoors, especially the opposite strong light in the low light environment at night, has caused great discomfort to the driver, and the momentary discomfort with the opposite strong light at night is one of the main reasons for traffic accidents. [0003] Ordinary sunglasses include polarizers that can filter out ultraviolet rays and block strong light. Daytime driving has a better protective effect on drivers. However, at night, in smog and rainy weather, the light transmittance is too low to affect the normal use. In addition, car film is becoming more an...
