Description

Mirror and multi-function glasses with the mirror

The present invention relates to a pair of glasses, and more particularly to a set of mirrors and multifunctional glasses having the set of mirrors.

Wearing glasses can not only be used to correct a variety of vision problems (including myopia, hyperopia, astigmatism, presbyopia or strabismus), but also to protect the eyes or for decorative purposes. In daily life, each user is usually not limited to wearing only one pair of glasses. For example, for middle-aged and elderly people, there may be problems with both myopia and presbyopia. When you need to see the near objects, you need to wear reading glasses, and the distant objects cannot be seen at this time. Therefore, when you need to see a distant object, you need to replace it with myopia glasses. Frequent replacement of glasses will undoubtedly bring a lot of inconvenience to users. In order to solve the problem of frequent glasses replacement, the user needs to customize the lens to be able to look at the vicinity and look at the distance at the same time. However, the customization cost is high.

In view of this, it is necessary to provide a holster and a multi-functional spectacles having the holster, which can solve the above problems.

The present invention provides a holster that includes a set of frames and a progressive multifocal lens secured to the set of frames, the progressive addition lens including a distally located region of the upper portion, the diopter of the distally facing region being zero.

The present invention also provides a multifunctional spectacles comprising: a primary mirror including a primary frame and a primary lens fixed to the primary frame; and a set of mirrors including a set of frames and fixed to the set of frames a progressive multifocal lens, the set of frames being fixed to the main frame such that the main lens is superimposed with the progressive addition lens, the progressive addition lens comprising a viewing area at an upper portion, The diopter in the far field is zero.

The holster mirror of the preferred embodiment of the present invention includes a progressive addition lens, and the refracting power of the far vision region of the progressive addition lens is zero, so that when the holster mirror is superimposed with the main mirror, the main mirror is The diopter of the corresponding area of the lens remains the same, allowing the user to still see distant objects. Therefore, the user does not need to frequently change the glasses, and at the same time, the mirror is matched with the ordinary lens, which is beneficial to avoid the cost increase caused by the personalized customization.

As shown in FIG. 1 and FIG. 2, a specific embodiment of the present invention provides a multifunctional eyewear 1 including a primary mirror 200 and a set of mirrors 100.

The main mirror 200 includes a main frame 202 and a main lens 201 fixed to the main frame 202. In the present embodiment, the main lens 201 is a myopic lens.

The holster 100 includes a holster frame 102 and a progressive addition lens 101 (shown in Figure 2) secured to the holster frame 102. The progressive addition lens 101 is formed by an injection molding process using a cyclic block copolymer (CBC). The density of the CBC is less than 1 g/cm ³ , so the progressive addition lens 101 is light in weight.

In the present embodiment, the sleeve frame 102 can be fixed to the main frame 202 by magnetic or mechanical fixing, so that the main lens 201 and the progressive addition lens 101 are superimposed. At this time, the outer surface of the main lens 201 is in contact with the inner surface of the progressive addition lens 101. Since the existing lens curvature is generally 250 bends (+2.50D) to 1000 bends (+10.00D), the progressive multifocal lens 101 has a curvature of +2.50D~+10.00D, making it compatible with any lens. A better match is achieved, i.e., the hood 100 can be adapted for different types of primary mirrors suitable for outdoor, outdoor and special sports.

The progressive addition lens 101 includes a distally located region 11 at the upper portion, a near-proximal region 12 at the bottom, a transition region 13 between the distal-facing region 11 and the near-proximal region 12, and an astigmatic region 14 at the edge. The diopter of the far field 11 is zero. The near-field 12 is used to correct near-power diopter. The transition zone 13 is for connecting the remote view area 11 and the near view area 13 with a diopter continuously increasing from the far field area 11 to the near view area 13. The astigmatic area 14 is generated due to a change in the curvature of the surface of the progressive addition lens 101 during design, which may cause visual blur or deformation to some extent. Therefore, the remote area 11 and the near area 12 and the transition zone 13 constitute an effective field of view of the progressive addition lens 101. Since the diopter of the far-field area 11 is zero, the diopter after the superimposed area of the main lens 201 and the far-field area 11 remain unchanged.

In the present embodiment, the diopter of the near-field 12 is set according to the degree of the user's presbyopia, and is preferably +0.75D to +2.50D. The width of the remote area 11 and the near area 12 is relatively large, about 6 mm to 20 mm. The transition zone 13 has a channel length of 15 mm to 25 mm and a channel width of 2 mm to 7 mm. In this way, the user is made to have a higher degree of comfort when wearing.

For users who have both myopia and presbyopia problems, if the lens that was originally worn (ie, the main lens 201) is a myopic eyeglass, it will result in a situation where the near object is not clearly visible. However, after the corresponding area of the main lens 201 is superimposed with the near-field area 12, since the near-field area 12 can be used to correct the near-power diopter, the user can see the near object. At the same time, the remote viewing area 11 is an area that is generally used by the user for a long time. Since the diopter of the corresponding area of the main lens 201 and the remote viewing area 11 remain unchanged, the user can still see the far distance. Object. Therefore, the user does not need to frequently change the glasses, and at the same time, the mirror 100 is matched with the ordinary lens, which is beneficial to avoid the cost increase caused by the personalization.

Of course, in other embodiments, the main lens 201 is not limited to a myopic lens, and may also be an astigmatic lens. Since the diopter of the corresponding area of the main lens 201 and the remote area 11 remain unchanged, the user does not affect the distant object.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to the preferred embodiments thereof, those skilled in the art Modifications or equivalents are not to be construed as a departure from the spirit and scope of the invention.
