Novel driving lens and manufacture method thereof

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...

Problems solved by technology

[0005] The inventor's utility model patent - blue light suppression coated lens (Patent No. ZL2012205234187) introduces a lens whose transmittance at different wavelengths is enhanced or suppressed by vacuum coating, proposes the concept of blue light protection and introduces a new type of anti- The preparation method of blue light lens, this product is effective in daily computer protection, but it is still not enough for driving in low light environment, mainly manifested as insufficient blocking of strong light below 500nm

[0006] The inventor's invention patent - blue light suppression resin lens (patent number: ZL2013208924155) modified the lens on the basis of the above patent, and added BLUE-BLOCKER coloring, through the combination of the three, the manufacturing process of blue light suppression It is more complete and suitable, but there is no step-by-step coloring process, and the light transmittance control for different viewing distances and the strong light blocking of the driving environment are not sufficient enough
