As the magnetizable member 5, a magnetizable metal, rubber, synthetic resin, etc. can be used, and if necessary, ferrite used as a permanent magnet may be used as the magnetizable member. In this case, the permanent magnet member 7 on the side of the small lens 6 can be made of a magnetizable member, and when both of them are made of ferrite, rubber containing ferrite, synthetic resin, etc. The power has improved further, and the small lens 6 to Klings 4, 4,
6 becomes even more secure.

This invention utilizes the attraction force of a permanent magnet to attract and fix the small lenses 6, 6 to the rings 4, 4, and also allows the small lenses 6, 6 to be positioned at the inner lower part of the eyeglass lenses 3, 3. ,6
It can be used as near vision glasses. Further, when unnecessary, the small lenses 6, 6 can be removed and carried, and even when looking at a distant place through the spectacle lenses 3, 3, the field of view will not be particularly narrowed. Moreover, since the spectacle lens 3 only needs to be a single lens, it can be made at a lower cost than a compound lens, and the power of the left and right small lens can be changed according to the visual acuity, making it extremely convenient and convenient for bifocal glasses. have
