Abstract

Some embodiments of the present disclosure include a device for improving a user's sighting swimming technique, particularly in open waters. The device may be a pair of goggles that includes a lens and an angle-dependent darkening mechanism configured to darken a portion of the lens depending on an angle of the user's head. In some embodiments, the goggles may include a front transparent lens, a rear transparent lens, and a cavity between the front transparent lens and the rear transparent lens; and the darkening mechanism may be volume of opaque liquid filling a portion of the cavity. Alternatively, the device may be a detachable lens configured to attach to a standard pair of goggles, wherein the detachable lens includes a front transparent lens, a rear transparent lens, a cavity between the front transparent lens and the rear transparent lens, and the darkening mechanism positioned within the cavity.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A pair of swim goggles for improving a user's sighting swimming technique, the swim goggles comprising:
 a lens; and   a darkening mechanism configured to darken a portion of the lens depending on an angle of the user's head.   
     
     
         2 . The swim goggles of  claim 1 , wherein the darkening mechanism is a member selected from the group consisting of a volume of opaque liquid, a rolling material, an angle-dependent holographic material, and an electronic darkening lens. 
     
     
         3 . The swim goggles of  claim 1 , wherein:
 when a user's head is positioned such that a normal field of vision is perpendicular to the ground, the darkening mechanism is configured to block a bottom half of the lens, such that a user can only see out of a top half of the lens;   when the user is swimming and looking straight ahead, the darkening mechanism is configured to block about half of the lens;   when the user is looking downward, the darkening mechanism is configured to block an entire surface of the lens, such that the user cannot see through the lens.   
     
     
         4 . The pair of swim goggles of  claim 1 , wherein:
 the goggles comprise a front transparent lens, a rear transparent lens, and a cavity between the front transparent lens and the rear transparent lens; and   the darkening mechanism comprises a volume of opaque liquid filling a portion of the cavity.   
     
     
         5 . The pair of swim goggles of  claim 4 , wherein the volume of opaque liquid is equal to about half a volume of the cavity. 
     
     
         6 . A device for mimicking a field of vision available to a swimmer when swimming in open waters, the device comprising:
 a detachable lens configured to removably attach to a pair of swimming goggles, the detachable lens comprising:
 a darkening mechanism configured to darken a portion of the detachable lens depending on an angle of a swimmer's head; and 
 a fastener configured to engage with a pair of goggles, such that the detachable lens is removably attached to the goggles and aligned with a goggle lens. 
   
     
     
         7 . The device of  claim 6 , wherein the darkening mechanism is a member selected from the group consisting of a volume of opaque liquid, a rolling material, an angle-dependent holographic material, and an electronic darkening lens. 
     
     
         8 . The device of  claim 6 , wherein:
 when a user's head is positioned such that a normal field of vision is perpendicular to the ground, the darkening mechanism is configured to block a bottom half of the lens, such that a user can only see out of a top half of the lens;   when the user is swimming and looking straight ahead, the darkening mechanism is configured to block about half of the lens;   when the user is looking downward, the darkening mechanism is configured to block an entire surface of the lens, such that the user cannot see through the lens.   
     
     
         9 . The device of  claim 6 , wherein:
 the goggles comprise a front transparent lens, a rear transparent lens, and a cavity between the front transparent lens and the rear transparent lens; and   the darkening mechanism comprises a volume of opaque liquid filling a portion of the cavity.   
     
     
         10 . The device of  claim 9 , wherein the volume of opaque liquid is equal to about half a volume of the cavity.
