Puckerings has dated this piece to the 1900s.

They focus wonderfully with leather covered sun shades which pull out to reduce glare in bright light and sunshine.
What is rather nice and unusual is the gold embossed makers mark to the front of the case "Heath & Co. Ltd. - Opticians To The Admiralty - Grayford, London".

Excellent condition measuring 5" wide x 4 1/2" tall extending to 6 1/2" while fully extended and the sun shades pulled out.
