more particularly refers to improvements in de
vices for protecting the eyes of the wearer against
injury from ?ying particles of glass or metal and
also against the effects of light brilliant enough
to be otherwise injurious to the sight and to inter

Accordingly, my improved shield can be used
under war conditions to protect the eyes against 10

burn with an intense light that no eye can bear.
