As shown in FIG. 1 and FIG. 2 , the present embodiment provides a lens, which includes a main body 11 located on the front side of the eye and two side wings 12 bent from both sides of the main body 11 to the side of the eye. The portion 11 and the side wings 12 are made by an integral molding process. The surface of the main body part 11 and the side wing part 12 facing away from the eye is defined as the outer surface, and the surface facing the eye is defined as the inner surface. The outer surface or the inner surface of the main body part 11 also has an optical film 21. The two sides of the main body portion 11 are bent along the two side edges of the main body portion 11 to be attached to the side wing portion 12 , and partially or completely cover the side wing portion 12 . Since the optical film 21 also covers the side wing portion 12, the side wing portion 12 also has the same functions as the main body portion 11, such as discoloration, polarization, etc., and can also effectively filter residual light and stray light. As a result, the problem of glare is caused, and at the same time, the side wings 12 also provide protection for the sides of the eyes, and can also prevent sand and soil from entering the eyes during sports such as cycling, thereby improving the user experience. The optical film 21 mentioned here may be an optical film in the prior art, such as polarizing film, color-changing film, and color-changing polarizing composite film.

The process of attaching the optical film to the lens can be realized by the conventional intracavity filming technology. For the specific operation process, please refer to the realization of the intracavity filming technology mentioned in Chinese patent CN104416738A, so it will not be discussed here. technology is detailed.

In this embodiment, preferably, the optical film 21 is located on the outer surface of the lens. Disposing the optical film 21 on the outer surface can have a better optical effect than the optical film 21 on the inner surface, without problems such as rainbow stripes, and can provide better optical functions. 21 being arranged on the outer surface also facilitates the positioning of the optical film 21 when the film is pasted in the cavity, and also simplifies the injection molding and laminating mold, which can better control the quality of the film in the cavity and facilitate cost control.

Example 2

In this embodiment, referring to FIG. 3 and FIG. 4 , this embodiment also provides a lens, which is based on the lens provided in Embodiment 1, by dividing the vertical line between the orthographic projection of the side wing portion 12 and the main body portion 11 . The included angle α is limited to 0-25°, preferably 0-20°, more preferably 0-10°.

Since there is a small angle between the vertical line of the orthographic projection of the side wing portion 12 and the main body portion 11, when the lens is impacted, the side wing portions 12 on both sides can support the main body portion 11 similar to a support column. effect, so that the lens can have better impact resistance.

It should be noted that the side wing portion 12 is a plane lens, and may also be a cylindrical, arcuate or spherical lens. When the side wing portion 12 is a plane lens, the vertical line of the orthographic projection of the side wing portion 12 and the main body portion 11 The included angle α between them is the included angle between the edge of the flank portion 12 and the vertical line of the orthographic projection of the main body portion 11 ; and when the flank portion 12 is a curved or spherical lens, the orthographic projection of the flank portion 12 and the main body portion 11 The included angle α between the vertical lines refers to the included angle between the tangent line of each point on the side wing portion 12 and the vertical line of the orthographic projection of the main body portion 11 . It should be additionally noted that the corner portion where the main body portion 11 and the side wing portion 12 are connected is not included in the limited range of the included angle.
