folding opera glasses

Twentieth century theatre glasses were usually of cheap plastic. Whilst playgoers could buy their own it was more usual to hire them from a dispensing unit on the back of the seat in front. The first picture shows a pair of 'Tivoli'' opera glasses by the well-known firm of Kershaw. (PAT. No 410292). In the twentieth century 'skeleton' pairs were also popular on account of their light weight and portability. We show a pair of folding opera glasses in nickel silver (?) with a lever-driven sliding action. The objective lenses screw in, whilst the eyepieces have eye-shaped cups - a thoughtful touch. This is a French example, marked 'Archimede'. Oval eyes compensated in part for the limited visual field provided by round opera glasses. They were also better for users with a wide inter-pupillary distance since, unlike field glasses, very few antique opera glasses had folding bridges adjustable for p.d. The oval-eyed opera glasses pictured with ivory barrels date from the early 20th century and bear the name of H. Oltzappfel & Co of 64 Charing Cross, Opticians to the Prince of Wales.

They are made mainly of brass and have an adjusting wheel at the centre for the focus. The large lenses fold down flat for portability. Although these glasses do not have a case, they are in very good condition for their year and the glass is not damaged.
