Description

(54) SHIELD ATTACHMENT FOR SPECTACLES (71) I, WALTER STANLEY BADGER, British Subject, 165 Pantmawr Road, Rhiwbina, Cardiff, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to shields of the kind adapted to be fitted to spectacles to protect the lenses from being obscured by rain spots. The main object is to provide very light weight shields of clear material, inexpensive and easy to manufacture.

The purpose of this attachment is to prevent rain reaching the lenses by fitting a shield wherein the horizontal portion extends forward some 45 mm. from the curved recess which abuts the forehead and combined with the downturned sidepieces keeps both sides of the lenses almost entirely free from rain spots.

The shield may be made from one of several different light weight materials preferably clear plastics with soft plastic forehead lining and synthetic sponge rubber pads.

The shield is ever ready for use and instantly attached or removed. To attach the shield to the spectacles the bottom edges of the side-pieces are pulled apart enough to allow the shield to be placed over worn spectacles. Once in position the side-pieces are released from tension which urges the pads into contact with the spectacle arms.

Thus the shield remains firmly in position on most designs of spectacles until removed by reversing the action described.

The preferred shape and dimensions are the result of wide ranging tests to discover the optimum of efficiency with comfort and visual acuity. The shield maintains unimpaired forward vision in most rain conditions, in squalls with wind driven rain at almost horizontal planes a few rain spots may reach the bottom of lenses leaving the remainder free and clear for most outdoor activities. Satisfactory tests include Golf, Fishing, Boating, Cycling and spectator sports.

Alternatively the shield attachment as already described may be made from tinted material endowing the shield with screening qualities. Used thus in bright sunlight the wearer enjoys relief from glare in many ways obviating the need to impose a dark and colour distorting filter in front of the eyes. From another aspect anti-glare screening may be obtained by printing or otherwise obscuring the shield from opaque nearest the forehead with diminishing shading to nil or clear at the forward extremities of both horizontal and side pieces.

Apart from giving relief for many outdoor activities similar comfort may be experienced in artificial light and television viewing. This type of anti-glare shield can demonstrate an advantage over many other devices when motoring especially when moving from bright sunlight to shadow and vice verso.

WHAT I CLAIM IS:- 1. A shield attachment for spectacles comprising a clear waterproof shield which in use extends generally horizontally forward over the front part of the spectacles frame and has downturned sidepieces urged resiliently inwards to engage the arms of the shield on the frame.

2. A shield attachment as claimed in claim 1, wherein it has a curved recess to abut the wearer's forehead.

3. A shield attachment as claimed in claims 1 and 2 and has a soft plastics lining along the curved recess.

4. A shield attachment as in claims 1, 2 and 3 wherein it has a sponge pad on the inside of each sidepiece.

5. A shield attachment as in claims 1, 2, 3, and 4 wherein the shield extends forward over the spectacle frame to a point where it screens efficiently against rain or glare.

6. A shield attachment as shown in Figures 1-7 of the accompanying drawings, and substantially as herein before described.
