Goggles with prism

摘要

Conventional swimming, anti-chlorine goggles only ensure the view underwater and the protection of the eye from water and chlorine. The following problem arises when swimming, using freestyle or butterfly, when the head is below the water and breathing takes place to the side or only once every two-three strokes. So that oncoming male/female swimmers are noticed and the distance from the edge of the pool is assessed properly for a precise turn, the head has to be lifted from time to time or orientation has to be sought from pool markings. This problem is solved by the feature specified in the claim. The prism (1) located in the upper third of the visual range and closely in front of the eye deflects upwardly the line of sight (2) of the eye, that is to say forwards past the forehead when lying on the stomach. (3) As a result, despite having the head underwater, it is possible to see what happens above the surface. This permits the swimmer to look forward without unnecessary head movement and thus to maintain the rhythm or to assess more precisely the distance from the edge of the pool. This principle for expanding the visual range can be applied in many areas, such as for example diving or gliding. <IMAGE>
