Title: Nose protective seal for spectacles
Inventor: NAKADA BUNJI
IPC: G02C11/00
Filed: 2001-05-24
Abstract: PROBLEM TO BE SOLVED: To provide spectacles which disperse pressure by widening contact points to prevent the concentration of the pressure of the spectacles to the skin so as not to leave the traces of the spectacles which remain on the nose on wearing of the spectacles for a long time, are conspicuous after removal of the spectacles and heretofore make persons dislike wearing the spectacles. SOLUTION: Weakly tacky adhesive glue is applied to the rear surfaces of felts 1 and the felts are attacked to pads of the spectacles so as to comply with the shape of the nose. The felts have the tacky adhesive surfaces and can therefore be fixed to the two points of the pads to impart tension between the two points. This tension accepts the pressure acting on the nose along the peak of the nose, thereby dispersing the pressure.
