Title: Eyewear having a mesh eye shield

Description:
FIELD OF INVENTION 
     This invention relates to eyewear having a mesh eye shield. 
     BACKGROUND 
     It is known to form eyewear having an eye shield which is made from mesh. It is an object of a preferred form of the invention to provide novel and inventive mesh eyewear which provides a useful alternative to at least some of such known products 
     The term “comprising” or derivatives thereof, if and when used in this document should be interpreted non-exclusively, eg to mean “consisting of or including”. 
     SUMMARY OF THE INVENTION 
     According to one aspect of the invention there is provided eyewear having an eye shield of mesh where the mesh has been formed by chemical etching involving the steps of applying a protective coat to a suitable sheet material, creating openings in the protective material, and subjecting the sheet material to a suitable liquid or gas such that mesh spaces are formed at the openings. 
     Preferably the mesh contains openings that are generally hexagonal in shape. 
     Preferably there are two separate eye shields, one for each eye. 
     Preferably the eyewear is in the form of goggles. 
     Optionally the eyewear is in the form of eye glasses. 
     Preferably the mesh is formed of a suitable metallic and/or plastic substance. 
     Preferably the mesh is formed of stainless steel. 
     Preferably the chemical etching involves the steps of applying a protective coating to a suitable sheet material, creating openings in the protective coating, and subjecting the sheet material to a suitable liquid such that mesh spaces are formed at the openings. 
    
    
     
       DESCRIPTION OF THE DRAWINGS IMAGES 
       Some preferred forms of the invention will now be described by way of example and with reference to the accompanying drawings, of which 
         FIG. 1  is a perspective view of a pair of safety goggles, and 
         FIG. 2  is a front magnified view showing an eye shield forming part of the safety goggles. 
     
    
    
     DETAILED DESCRIPTION 
     Referring to  FIG. 1  the eyewear  1  has an eye shield  2  which consists of two separate pieces. In other embodiments of the invention the eye shield  2  may consist of one piece. The eye shield  2  is made of mesh  3 . The mesh  3  is made of a suitable metallic and/or plastic substance such as stainless steel. The mesh  3  is formed by chemical etching. The chemical etching involves the steps of applying a protective coating to a suitable sheet material, creating openings in the protective coating, and subjecting the sheet material to a suitable liquid such that mesh spaces are formed at the openings. in other embodiments of the invention the sheet may be exposed to a gaseous acid or an alkali rather than the liquid mentioned above. 
     The eyewear  1  has a pair of strap connectors  4  on the right and on the left of the rear facing side of the goggles.  FIG. 1  does not show a strap for attaching the eyewear  1  to a user&#39;s head but according to one preferred embodiment of the invention the eyewear  1  is secured to a user&#39;s head by a flexible head strap that is attached at each end to the strap connectors  4  respectively, In other embodiments of the invention the eyewear  1  can be secured to a user&#39;s head with two arms curved at each end to form ear hooks as is normal with eye glasses. When the eyewear I is worn the eye shield  2  protects the eyes. 
     Referring to  FIG. 2 , a magnified view of the mesh  3  shows that the mesh  3  consists of openings  5  which are generally hexagonal in shape  6 . The hexagonal shape of the openings  5  in the mesh  3  give the mesh more strength than would be the case with quadrilateral-shaped mesh spaces. 
     While some preferred forms of the invention have been described by way of example it should be appreciated that modifications and improvements can occur without departing from the scope of the following claims.
