Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Example 1

As shown in fig. 1 and 2, the present embodiment provides a lens, which includes a main body 11 located at the front side of the eyes and two side wing portions 12 bent from two sides of the main body 11 to the sides of the eyes, wherein the main body 11 and the two side wing portions 12 are manufactured by an integral molding process. The surfaces of the main body part 11 and the side wing parts 12 which are away from the eyes are defined as outer surfaces, the surfaces which face the eyes are defined as inner surfaces, the outer surfaces or the inner surfaces of the main body part 11 are also provided with optical films 21, two sides of each optical film 21 are bent along two side edges of the main body part 11 to be attached to the side wing parts 12, and the side wing parts 12 are partially covered or completely covered. Because the optical film covers the side wing part 12, the side wing part 12 has functions such as color change, polarization and the like as well as the main body part 11, and can also play a role in effectively filtering residual light and stray light, thereby solving the problem of glare, simultaneously, the side wing part 12 also provides protection for the side surface of the eyes, and can also prevent sand from entering the eyes in riding and other movements, thereby improving the experience effect of users. The optical film 21 may be a polarizing film, a color-changing polarizing composite film, or other optical films in the prior art, and the preparation process of the optical film is the prior art, and therefore, the details thereof are not described herein.

The process of attaching the optical film to the lens can be realized by using the intracavity film attaching technology in the prior art, and the specific operation process can refer to the realization of the intracavity film attaching technology mentioned in CN104416738A, so the technology is not described in detail here.

In this embodiment, preferably, the optical membrane is located on the outer surface of the lens. Set up the optics diaphragm on the surface outward, for can have better optical effect with the optics diaphragm setting at the internal surface, rainbow stripe scheduling problem can not appear, can provide better optical function, also be convenient for simultaneously with the optics diaphragm setting on the surface outward to the location of optics diaphragm when the intracavity pad pasting, also can simplify the injection molding laminating mould moreover, the quality of control intracavity pad pasting that can be better and be favorable to the control of cost.

Example 2

In the present embodiment, referring to fig. 3 and 4, the present embodiment also provides a lens, which is based on the lens provided in embodiment 1, and the included angle α between the wing portion 12 and the perpendicular line of the main body portion 11 in the orthographic projection is defined as 0 to 25 °, preferably 0 to 20 °, and more preferably 0 to 10 °.

Because the wing parts 12 and the perpendicular line of the orthographic projection of the main body part 11 have smaller included angles, when the lens is impacted, the wing parts 12 on the two sides can support the main body part 11 similarly to a support upright column, so that the lens can have better impact resistance.

It should be noted that, the wing portion 12 is a flat lens, and may also be a cylindrical lens, an arc lens or a spherical lens, when the wing portion 12 is a flat lens, an included angle α between the wing portion 12 and a perpendicular line of the main body portion 11 in the orthographic projection is an included angle between a sideline of the wing portion 12 and a perpendicular line of the main body portion 11 in the orthographic projection; when the wing portion 12 is a curved or spherical lens, the angle α between the perpendicular line on which the wing portion 12 and the main body portion 11 are orthographically projected is an angle between a tangent line of each point on the wing portion 12 and the perpendicular line on which the main body portion 11 is orthographically projected. It should be noted that the corner portion where the main body portion 11 and the side wing portion 12 are connected is not limited to this included angle.

In actual testing, the lens shown in FIG. 3 was placed in an impact tester for MIL-PRF-32432(GL) MCEP standard bullet impact testing. The specific testing steps are that the impact tester is adjusted to a testing state, the lens is worn on a head model and positioned, and after a positioning area is closed, the impact test is carried out according to the MIL-PRF-32432(GL) MCEP standard. And after the test is finished, reading the data displayed by the impact speed display table to obtain a test value. The test result shows that the lens has no cracking and penetration problem under the impact force of 730Ft/sec, and the lens has good impact resistance.

Meanwhile, when the lens is impacted (for example, when the lens is impacted by scraping of branches during riding, scraping of the ground during falling, and the like), under the condition that a small included angle is formed between the orthographic projection perpendicular lines of the side wing parts 12 and the main body part 11, the impact stroke of a foreign object on the side wing parts 12 is relatively short, and therefore, the optical film on the side wing parts 12 is not easy to break under the impact. When the side wing 12 and the main body 11 have a large included angle, the impact stroke of the external object on the side wing 12 is relatively longer, which easily causes the optical film on the side wing 12 to be damaged under impact, and when the optical film is damaged, the optical film is easy to fall off wholly or locally, thereby affecting the function of filtering residual light and stray light.

Therefore, the side wing part 12 and the main body part 11 can not only improve the impact resistance of the lens in the included angle range, but also enable the optical film to have better adhesion, and further can ensure the function of filtering residual light and stray light of the side wing part 12.

Referring to fig. 3 and 4, the body portion 11 may be a myopic lens or a presbyopic lens having diopter, or a plain lens having no diopter. The main body 11 as a lens may be a plane, a cylinder, a curved surface, or a spherical surface.

In the present embodiment, referring to fig. 3 and 4, the main body portion 11 and the side wing portions 12 are connected by a folded corner portion 13 or a chamfered corner portion 14. The adoption of the bevel part 13 for connection can enable the whole lens to have relatively stronger impact resistance, and the adoption of the bevel part 14 can reduce wind resistance on the premise of ensuring necessary impact resistance, so that the use of the lens in riding is facilitated.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
