Abstract:
A plastic lens plastic includes a plastic substrate (1) having a first main surface that is a convex surface (1A) and a second main surface that is a concave surface (1B), a photochromic compound-containing photochromic layer formed on the convex surface side of the substrate, and an impact-absorbing primer layer formed on the concave surface side of the substrate.
Abstract:
An information processor includes a storage part configured to store multiple hierarchically correlated data elements; a metadata storage part configured to store the metadata of each of the data elements; an editing part configured to edit the metadata stored in the metadata storage part; and a reflection part configured to reflect the result of editing the metadata of one of the data elements by the editing part in the metadata of at least one of the remaining data elements.
