<P>PROBLEM TO BE SOLVED: To easily generate static electricity at a spectacle lens, when inspecting a charging state using the principle that particles for evaluation adhere to the spectacle lens by Coulomb force due to the static electricity. <P>SOLUTION: The charging state inspection tool for a spectacle lens includes: a body part 2 forming an airtight container capable of housing a spectacle lens 3; a lens holding part 4 for holding the spectacle lens 3 in the body part 2; and a large number of particles 5 for evaluation stored in the body part 2. The body part 2 has: a transparent part through which the spectacle lens 3 can be viewed from the outside of the body part 2; and space which is provided between the body part and the spectacle lens 3, and through which the particles 5 for evaluation can pass. The particles 5 for evaluation are composed of material which generates static electricity by coming into contact with the spectacle lens 3, and adhere to the spectacle lens 3 by Coulomb force due to the static electricity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
