Embodiment 1

[0057] see figure 1 , the invention discloses a treatment method for photochromic lenses, the treatment method comprising the following steps:

[0058] [Step S1] Environmental conditions: temperature 20-30°C, humidity 55-65% RH, soak the lens in chemical solution A and chemical solution B under different conditions and wash with RO water or pure water to form a uniform surface of the lens Microporous structure; specifically includes:

[0059] Step S11: Water washing step; use RO water to soak the lens in the first tank of the processing equipment, the temperature of the RO water is 35-75°C, the immersion time is 5-30 minutes, and the composite frequency is passed by a voltage of 220V and a power of 500w Ultrasonic irradiation;

[0060] Step S12: Corrosion step; immerse the lens treated in step S11 in the second tank of the processing equipment with chemical solution A, the temperature is 35-75°C, and the immersion time is 5-30 minutes; the chemical solution A includes a mass...

Embodiment 2

[0076] The method of the present invention forms a uniform honeycomb structure on the surface of the lens through a special process: first use a special ultrasonic device to clean the surface of the lens with a special chemical solution A to form a uniform honeycomb structure, and then use a special chemical solution B to form a uniform honeycomb structure. To neutralize the chemical solution A remaining on the surface of the lens, the following must be controlled during this process: the energy value of the ultrasonic wave, the preparation of the chemical solution A, the temperature and time of operation, and the conductivity of pure water must reach 16MΩ. cm or more), the purpose and advantage of this is that, while ensuring that the surface quality of the lens will not be damaged, it is beneficial to accommodate more discoloration factors per unit area of ​​the surface of the lens, enhancing the discoloration effect of the lens, and at the same time having enough space Provi...

Abstract

The invention discloses a photochromic lens treatment method which comprises the following steps: S1, soaking a lens in a corrosive solution and a neutral solution, and washing with RO (Reverse Osmotic) water or purified water so as to form a uniform micro-pore structure on the surface of the lens; and S2, dialyzing a photochromic factor into the surface of the lens treated in the step S1, wherein the photochromic factor is dialyzed into the surface of the lens through a photochromic dialysis solution or a free photochromic factor. The photochromic lens treatment method disclosed by the invention uses a pretreatment method for preparing a pretreatment structure of a lens and further treating the pretreatment structure before methods such as spinning and soaking, then a thin layer of uniform spatial structure similar to a honeycomb can be formed on the surface of a lens substrate, the accommodation number of the photochromic factors within a unit area can be increased, the spatial structure is beneficial to opening and closure functions of photochromic chemical bonds, and thus the photochromic effect and the photochromic fading timeliness of the lens can be improved.

Description

technical field [0001] The invention belongs to the technical field of lens processing, and relates to a processing method for a color-changing lens, in particular to a processing method for a color-changing lens. Background technique [0002] Photochromic lens is a kind of lens commonly used in modern mirror-making technology. This kind of lens is usually prepared by the following methods: [0003] 1. Substrate discoloration: Mix discoloration powder and lens material evenly and stir, form discoloration lens by casting or injection molding, so that the lens has discoloration function; [0004] 2. Spin coating or dip coating film layer discoloration: dissolve the discoloration powder into the coating solution, and then coat the surface of the lens with a discoloration coating by spin coating or dip coating technology, so that the lens has a discoloration function; [0005] 3. Attaching the color-changing film: the film with the color-changing effect is pasted on the surface...
