Problems solved by technology

[0005] This shows that above-mentioned existing eyeglass obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved
In order to solve the problems existing in the lenses, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above problems. This is obviously related. The problem that the industry is eager to solve

no. 1 example

[0041] refer to figure 2 As shown, a photochromic lens 20 according to the first embodiment of the present invention includes a body 21 . The body 21 has a first side 211 and a second side 212 , and the second side 212 is opposite to the first side 211 . The body 21 includes at least one photochromic material 213 .

[0042] The body 21 has a weight percentage of the photochromic material 213 ranging from 0.05% to 5%, wherein a preferred ratio is between 0.1% and 0.7%. In this embodiment, in order to prevent the photochromic material 213 from mixing into the main body 21 and interacting with the binder, the photochromic material 213 can be pre-coated into capsules by physical or chemical methods and then mixed into the binder . After the photochromic material 213 is mixed into the binder, the main body 21 is made by, for example but not limited to, injection molding.

[0043] The material of the body 21 can be glass or polymer, and the polymer can include thermosetting pol...

no. 2 example

[0047] Please refer to Figure 4 As shown, another photochromic lens 20a according to the second embodiment of the present invention includes a main body 21a.

[0048] The main body 21a is different from the above-mentioned main body 21 in that: the main body 21a further has a base color material 214 with a weight percentage between 0.1% and 5%. Under the condition that the main body 21a maintains high light transmittance without changing the transmittance, it can still provide a base color effect. When the color of the main body 21a changes, it visually produces an overlapping effect with the base color, and presents a different color on the photochromic lens 20a. In this embodiment, yellow is used as an example for the background color. Of course, the background color can be replaced by other colors or mixed and matched by colors and double-layer to multi-layer mix-and-match designs can be used to obtain different colors and concentrations according to actual needs. The ph...

[0050] Please refer to Figure 5 As shown, another photochromic lens 20b according to the third embodiment of the present invention includes a body 21 and a functional layer 22b. Since the main body 21 has been described in detail in the first embodiment, it will not be repeated here.

[0051] The functional layer 22b can be disposed on the first side 211 and / or the second side 212 of the body 21 by, for example but not limited to, soaking, deposition, spraying, coating or pasting. In this embodiment, the functional layer 22b is disposed on the first side 211 and the second side 212 of the body 21 as an example for illustration, but it is not intended to limit the present invention. The function of the functional layer 22b can be selected from anti-reflection (anti-reflection), waterproof (water-proofing), anti-fog (anti-fog), anti-scratch (anti-scratch), anti-ultraviolet (anti-UV) and other functions. The group formed by the combination.

Abstract

The invention relates to a photochromic lens, which comprises a body. The body is provided with a first side and a second side arranged opposite to the first side. The body contains at least one photochromic material. The photochromic lens reduces the transmitting degree of light to maintain visual comfort under strong light, and does not reduce the transmitting degree of the light under the dark light to provide high transmittance by applying the photochromic material. Compared with the prior art, the photochromic lens can automatically change the transmitting degree with strong-weak change of the light for maintaining visual comfort. In the production aspect, the photochromic lens can be applied to the prior production equipment, and widens the application range of the equipment.

Description

technical field [0001] The invention relates to a lens, in particular to a lens with a color-changing function. Background technique [0002] With the advancement of technology, lenses are an indispensable item in today's daily life. According to different functions, it can be divided into optical lenses and goggle lenses, which can be applied to optical glasses, sunglasses, protective glasses, contact lenses, safety helmet goggles or sun visors of sun hats, and even telescopes, microscopes or cameras Optical instruments such as optical instruments are common usage patterns. [0003] Please refer to figure 1 As shown, a known lens 10 includes a body 11 and a base color layer 12 . The base color layer 12 has a base color material 124, which can reduce the light penetration of the lens 10, so as to improve the discomfort caused by sunlight to the eyes. However, since the light transmittance of the lens 10 cannot change automatically with the environment, at night, indoors ...
