ABSTRACT:
The invention provides a pair of goggles which can be used for a variety of recreational activities, such as swimming, cycling, ball games etc. The goggles comprise of a pair of eyepieces and a nosepiece. Each eyepiece has a lens and rim, each rim having a first connecting structure and a headstrap connecting structure to receive a headstrap. The nosepiece has a pair of second connecting structures, and a bridge structure disposed between and integral with the second connecting structure. Each second connecting structure is complementary to a respective first connecting structure of the pair of eyepieces and forms an essentially rigid interference fit therewith. Inner portions of the second connecting structure and outer portions of the bridge means are contiguous and inclined at respective angles to each other at a rigid joint which is sufficiently stiff to resist deformation when subjected to normal loads occurring during use. In this way, the angles between the second connecting structure and the outer portions of the bridge means remain essentially unchanged during normal use.
