Abstract

PURPOSE:To facilitate the replacement of a convex lens and to obtain economical spectacles by dividing a right and a left lens into upper and lower parts, forming the lower lenses as farsighted convex lenses, and providing attaching and detaching means which allows the convex lenses to be attached to and detached from the upper lenses. CONSTITUTION:The right and left lenses of spectacles 1 are divided into two upper and lower parts; and the upper parts are protection spectacle lenses 2 having no diopter and the lower parts are farsighted convex lenses 3. The upper lenses 2 are held by an upper lens frames 4, which are coupled with each other by coupling frames 5 and 6; and side frames 8 are coupled in a free folding state with both outside parts of the frames 4 through L-shaped frames 7. The lower end slide contact surface 2a of each lens 2 and the upper end slide contact surface 3a of the lower convex lens 3 are linear and held by the lower lens frame 9 of the convex lens 3 and the upper and lower frames 4 and 9 form projection parts 4a and 9a at both inside and outside opposite end parts; and magnets 10 and 11 are provided inside the projection parts and the lower lenses 3 are allowed to be attached and detached by attaching and detaching means through the attraction of the magnets.

(B) Background of the Invention Conventionally, as the above-mentioned eyeglasses, for example, there are eyeglasses in which the lower portions of the left and right lenses are integrally formed with convex lenses for presbyopia.

In the case of these glasses, the entire lens is fixed to the frame, so when you look up close, such as when reading or writing, you can accurately see the object, such as letters, through the convex lens at the bottom. You can read it, but when you look down at your feet in the distance, like when you're walking down a flight of stairs while wearing glasses, make sure your eyes are facing downwards, that is, looking at the steps of the stairs to avoid tripping. In this case, because the visual field was viewed through a convex lens, it was difficult to focus, making the steps look blurry or distorted, making it difficult to descend smoothly, which was dangerous.

(D) Summary of the Invention This invention divides each left and right lens into upper and lower halves, forms the divided lower lens into a convex lens for presbyopia, and attaches the convex lens to the lower lens removably. The glasses are characterized by being equipped with a means for putting on and taking them off.

In addition, when you are going down stairs with glasses on or off and don't need a convex lens, you can remove the convex lens and use only the upper lens to see, even if your eyes are directed downwards when looking at the steps of the stairs. Since the step is not performed through a convex lens, steps are not blurred or distorted/V, and the stairs can be smoothly descended.
