ABSTRACT:
Spectacles which can be put on together with other ordinary spectacles to correct, among others, age-related or non-age-related farsightedness, and which are extremely lightweight, compact and easy to carry. The spectacles include an elongate bar member formed by molding a synthetic resin and having a pair of lens portions having edges, and a bridge portion coupling the edges of the respective lenses together. Temples are foldably coupled to both ends of the bar member by hinges. The lenses have a vertical width substantially equal to the vertical width of the temples. The bridge has an arcuately curving back face which serves as a nose pad. The bar member has at both ends thereof rodlike projections protruding forwardly beyond the front faces of the lenses. Also, cases for such spectacles are proposed.
