| titleOfInvention | Diving mask with lens and method of manufacturing the same |
| abstract | (57) [Summary] [Purpose] To provide a diving mask which eliminates distortion of the visual field in water and can be used both by water with or without normal vision, people with myopia and hyperopia. [Structure] A flexible surface main body 14 and a peripheral surface of the surface main body 14 The main lens 12 having a substantially hemispherical shape and the peripheral edge of the main lens 12 are substantially aligned with the contour of the user's face, and the center of curvature of the main lens 12 is the optical nodal point of the eyeball 24 of the user or Fit it so that it matches the center of rotation. The lower lens 190 for making it easier to see the object at hand is used as the main lens 1 2, a movable or fixed correction lens 112 is provided in the diving mask 10 in order to correct the visual acuity of myopia. The main lens 12 may be provided with a drain valve 126 that allows the user to blow out his / her nose and drain the water that has entered the diving mask 10. |
