Abstract

The invention provides a manufacturing method for a hardened film resin lens. According to the lens, a novel hardening liquid which is manufactured by blue light wavelength conversion particles is blended and used to perform dip-coating treatment on the surface of the lens on the basis of the existing lens film coating process flow treatment, blue light with the wavelength of 400 to 480 nm which is harmful to a human body is converted into low-frequency near infrared light with the wavelength of 850 to 950 nm; the original blue light preventing capacity of the lens is remarkably improved on the premise of ensuring light transmittance of the lens; the blue light attenuation rate is increased from original 10 to 20 percent to above 80 percent; the blue light transmittance is attenuated selectively, and meanwhile, the overall light transmittance of the lens is taken into consideration; the window transfer transmittance adjustment of the blue light frequency is realized; the manufacturing method has the characteristics that the creativity is novel, the technology is unique, the process is simple, the practicability is high, and the blue light attenuation rate can be selectively adjusted.

Description

A kind of manufacture method of stiffened film resin eyeglass

Technical field

The present invention relates to anti-blue light resin lens make applied technical field, particularly relate to a kind of anti-blue light resin lens being coated with blue light wavelength conversion particles stiffened film layer and preparation method thereof.

Background technology

The radioprotective eyeglass generally sold on glasses market now is the indium stannum alloy conductive film layer of stiffened one layer of 20 200 nano thickness of film surface vacuum evaporation in resin lens, realize the decay shielding action to high frequency electromagnetic radiation using the electric conductivity of indium stannum alloy, but indium is rare metal, excavating with exploitation in ground in the layer reserves can be fewer and feweri, when eventually having resource exhaustion, if can manage to solve the shielding problem of electromagnetic radiation as resin lens surface coating using the extremely abundant carbon series of conductive product of present on earth amount, the space of great development and application will be had.

A kind of anti-blue light resin lens manufacture method of Chinese patent 201310408405.4 and product employ to be dosed the method for blue-light absorbers (o l p melanin powder) to absorb and to scatter blue light energy in heat curing-type optical resin monomer，Decrease passing through of blue light，It is reported that，When the addition of o l p melanin powder is in 600-800ppm，The product made can stop more than 90% blue light，But o l p melanin powder belongs to the light absorbent of wide spectrum type，Its advantage is to high-frequency shortwave light such as purple light、The screening factor of blue light is more than the decay screening factor to low frequency light wave，But itself there is no window adsorption frequency，The Rectangular decay characteristic curve to blue light cannot be realized，Also reduce passing through of other frequency coloured light while decaying blue light，Reduce the integral light-transmitting rate of eyeglass.
