Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to distance vision glasses that do not require changing between myopia glasses and presbyopia glasses. 2. Description of the Related Art Conventionally, there has been a single-lens spectacle for bifocal use. [0003] This has the following disadvantages. It is good when reading and writing simple sentences and reading newspapers, but when working on a full-fledged desk work, such as design, it is necessary to work with different presbyopia glasses. The present invention has been made to eliminate these disadvantages. A lens (2) having a power for presbyopia is mounted on a lens frame (1) of a main body. The movable lens frame (3) which can be rotated or detached on the upper side is provided with a correction lens (4) having a power obtained by subtracting the power of the presbyopic lens (2) from the power for myopia. The present invention is a perspective glasses configured as described above. Hereinafter, embodiments of the present invention will be described. (A) A lens (2) having a power for presbyopia is attached to the lens frame (1) of the main body. (B) A movable lens frame (3) that can be rotated or detached on the upper side is provided with a correction lens (4) having a power obtained by subtracting the power of the presbyopia lens (2) from the power for myopia. The present invention has the above-mentioned structure. When used as myopia glasses, the presbyopia lens (2) attached to the lens frame of the main body and the correction lens (4) attached to the movable lens frame (3) that can be rotated or detached. ) And look at the object through the two lenses. When used as presbyopia glasses, the movable lens frame (3) that can be rotated or detached is raised, and objects are viewed only with the presbyopia lens (2) of the main body. As a specific example, in the case of a person having a near-sighted power of −3.00 and a presbyopic power of −1.25, a power of −1.25 is provided to the presbyopia lens (2) of the main body, and − is provided to the upper correction lens (4). What is necessary is just to attach the frequency of 2.25. The relational expression of the power of the lens is -3.00 =
(-1.25) + (-2.25). The effect of the gap generated when the presbyopia lens (2) of the main body and the upper correcting lens (4) are combined has no problem in seeing an object. According to the present invention, there is no need to re-hook the eyeglass body, and the user is not bothered.
