Description: A pair of Hamblin's 'Full-Field' snow goggles with yellow-orange 'salvoc' lenses (a) in a metal case (b). Made by Theodore Hamblin Ltd. of London, and used throughout the British Graham Land Expedition 1934-37 (Penola). The lenses of this pair have been ground to a special curvature to avoid the use of two pairs.

Full description:

goggles (a): The goggles consist of two yellow-orange 'salvoc' (a trade name for a type of reinforced safety glass produced by inserting a sheet of cellulose acetate between two layers of glass) glass lenses set into aluminium frames, with sides made from a double layer of waterproof fabric. The eye pieces are triangular in shape, giving increased downward and lateral vision, and the lenses are starting to delaminate. According to the accession register, the lenses have been ground to a special curvature so as to avoid the use of two pairs. The fabric has been almost completely cut away at the sides – presumably a modification to increase the amount of ventilation. The frames have small clips/tabs which fit over the fabric and help hold it in place. The metal rims are covered with velvet and lined with a furry textile, so that no metal touches the face and causes frostbite. The eye pieces are joined together across the nose by a strip of brown leather which feeds through a slot on the aluminium frame. They are further joined by a metal staple which fits into small tubes attached to the frames of each eye piece, which give the goggles both stability and a small measure of flexibility. A piece of string has been tied to the outer aluminium frame and the inner velvet covered-rim at the side of each eye piece, to counteract the natural spring of the inner rim. The black elastic headband (16mm wide) has two three-way joins, to create a strap which passes over the head and an angled strap which passes round the back of the head. The headband is fitted to the frame by means of an aluminium hook on either side, and has two metal adjustors.

case (b): The metal case is painted black and is heavily scratched in places. The lid of the case is hinged along the long edge, and has a paper label which reads: 'British Graham Land Expedition // 1934/7 // "Full-Field" Goggles // (Salvoc Yellow) // Made by // Theodore Hamblin Ltd. // Dispensing Opticians // 15. Wigmore Street, London. W.1'
