Description

  The present invention relates to eyeglasses, and more particularly to an improved structure for attaching a second lens or auxiliary lens to the eyeglasses. More specifically, the present invention relates to a structure in which a main lens and an auxiliary lens are provided with protrusions that cooperate and fit with each other so that the main lens and the auxiliary lens can be mechanically detachably connected.

  The spectacle wearer often desires to attach a second lens to the spectacles to protect the eyes from the sun and ultraviolet rays. Thereby, it becomes unnecessary to carry sunglasses separately, and the wearer can also obtain the effect of sunglasses while obtaining visual acuity with a prescription lens. In some cases, the auxiliary lens is provided with various clips in order to detachably fix the auxiliary lens to the main lens and immediately convert the main lens to sunglasses. Conventionally, there are various forms for attaching the auxiliary lens. One example is the use of a clip that hangs on the bridge of the main spectacle.

Another structure for detachably mounting a pair of auxiliary lenses on a pair of main spectacles is described in Patent Document 1. The patent discloses spectacles with a spectacle frame support for main lens support that includes side portions each having an extension for rotationally connecting the legs and two back portions to which the projections are respectively fixed. doing. The main spectacle frame includes an upper portion and a pair of first magnetic members fixed in the protrusions.

  Although the above-described clip structure and magnetic attachment have a function of fixing the auxiliary lens to the main frame, there are many problems. The clip structure is heavy and difficult to handle, and the appearance is not beautiful, and there is a risk of damaging the main lens when the auxiliary lens is attached to the main spectacle frame. The magnetic structure described in Patent Document 1 is also disclosed in Patent Document 2 by Sadler and Patent Document 3 by Richard Chao. One of the problems with magnetic structures is that the magnetism declines over time and the mounting effect is greatly reduced. Even when the magnetism is in the strongest state at the time of frame manufacture, especially when the user is engaged in sports such as jogging, jumping, and tennis, the magnetic force may not be able to withstand the dynamic load applied to the auxiliary frame. While the user is engaged in strenuous exercise, the auxiliary spectacle frame may come off from the main spectacle frame, and the auxiliary spectacle frame may be damaged, causing inconvenience to the user.

  Further, the magnetic surface in the protrusion provided on the main frame is easily rusted, and the magnetic effect may be reduced. As a further problem, the magnetic surface allows a range of movement on the surface of the magnet, so that the auxiliary frame moves relative to the main frame with the auxiliary frame attached to the main spectacle frame. there is a possibility. As a result, the gap between the auxiliary frame and the main spectacle is widened so that sunlight passes through the lens of the main spectacle frame, and the effect of attaching the auxiliary lens to the main spectacle lens is reduced as a whole.
