     DETAILED DESCRIPTION 
     Various aspects of the disclosure will now be described with regard to certain examples and embodiments, which are intended to illustrate but not to limit the disclosure. Nothing in this disclosure is intended to imply that any particular feature or characteristic of the disclosed embodiments is essential. The scope of protection is defined by the claims that follow this description and not by any particular embodiment described herein. Before turning to the figures, which illustrate example embodiments in detail, it should be understood that the application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting. 
     Embodiments herein generally relate to a lens cleaning system (e.g., a continuous roll-off system, a wiper system, etc.) configured to facilitate cleaning a lens of eyewear (e.g., goggles, glasses, sunglasses, protective eyewear, etc.). The lens cleaning system may be configured to facilitate selectively cleaning the lens (e.g., removing debris from the lens hindering the vision of the wearer, etc.) in a relatively simple manner (e.g., easy, quick, etc.) and/or facilitate providing continuous cleaning (e.g., such that components of the lens cleaning system do not need to be refilled or replenished, etc.). Such eyewear having the lens cleaning system may be used in a number of activities, including without limitation: sports and athletics, including extreme sports such as motocross and snowmobiling; cycling activities, including auto racing, motorcycle riding and racing, BMX, mountain biking, etc.; with recreational vehicles including all-terrain vehicles (ATVs), dirt bikes, utility task vehicles (UTVs), snowmobiles, and other off-road vehicles; military applications; and/or construction applications to name just a few. Further details are provided herein. 
     According to an exemplary embodiment, the eyewear of the present disclosure includes a frame, a lens disposed within the frame, and a lens cleaning system coupled to the frame and/or the lens. Some traditional lens cleaning systems may include a non-continuous roll-off system having a roll of film that is selectively translated across the lens from one canister to another as the film becomes dirty (e.g., with dirt, mud, water, snow, etc.). Other traditional lens cleaning systems may include a rip-off system having a plurality of rip-off film elements that couple to the eyewear and may be torn or ripped off one-by-one as each becomes dirty. Such traditional lens cleaning systems only remain effective while there is a supply of film, such that once the roll of film or the rip-off film elements are spent, the wearer of the eyewear needs to replenish the lens cleaning system. Such replenishing of the supply of film may be disadvantageous, especially in competitive events where the wearer is unable to stop if the lens cleaning system is rendered unusable (e.g., which may lead to the lens becoming covered in mud, dirt, water, snow, etc. thereby hindering the vision of the wearer). Further, traditional lens cleaning systems may require that the eyewear includes a cylindrical lens that may cause distortion in the vision of the wearer (e.g., in a vertical plane, etc.). 
     According to an exemplary embodiment, the lens cleaning system of the present disclosure includes a continuous roll-off system having a continuous loop of film with a multi-stage debris removal system integrated into canisters. According to another exemplary embodiment, the lens cleaning system of the present disclosure includes a wiper system having a cable pulley system and a cleaning element (e.g., a wiper element, a squeegee element, etc.) that is translated across the lens by the cable pulley system. Advantageously, the continuous roll-off system and the wiper system eliminate the need to replenish film components (e.g., the roll-off film, the rip-off film elements, etc.) of traditional roll-off and rip-off systems. The wiper system may also advantageously facilitate the use of a toroidal lens and/or spherical lens. Such a toroidal and/or spherical lens may cause no or negligible distortion in the vision of the wearer in any direction. 
     According to the exemplary embodiment shown in  FIGS. 1-8 , eyewear, shown as goggles  10 , have a first lateral end, shown as right end  12 , and an opposing second lateral end, shown as left end  14 , and include a frame, shown as frame  20 ; a lens, shown as lens  30 ; a strap, shown as head strap  40 ; a cushion member, shown as compressible member  50 ; and one of (i) a first lens cleaning system, shown as continuous roll-off system  100 , and (ii) a second lens cleaning system, shown as wiper system  200 . According to an exemplary embodiment, the continuous roll-off system  100  and the wiper system  200  are configured to facilitate selectively cleaning the lens  30  (e.g., removing debris from the lens  30  hindering the vision of the wearer, etc.) in a relatively simple manner (e.g., easy, quick, etc.), while providing continuous cleaning (e.g., a film component of the continuous roll-off system  100  does not need to be refilled or replenished, the wiper system  200  does not include a film component, etc.). According to an exemplary embodiment, the eyewear are motocross goggles. In other embodiments, the eyewear are snowmobiling goggles, snowboarding goggles, mountain biking goggles, motorcycle goggles, sky diving goggles, or still another action or extreme sport goggles. In still other embodiments, the eyewear are or include swimming goggles or other sports goggles (e.g., used in basketball, baseball, etc.; Rec Specs®; etc.). In another embodiment, the eyewear is or includes a visor coupled to a helmet (e.g., a football helmet, a motorcycle helmet, etc.). In yet other embodiments, the eyewear are another type of eyewear used for construction, military applications, machining, carpentry, scientific experimentation, and/or the like. In still other embodiments, the eyewear are traditional vision enhancing glasses (e.g., prescription glasses, etc.) and/or sunglasses. 
     According to an exemplary embodiment, the goggles  10  provide protection to the eyes and adjacent area of the face of a wearer. The lens  30  and/or the frame  20  may intercept light, wind, rain, snow, water, particulate matter (e.g., dust, dirt, mud, etc.), and the like to protect the eyes and/or various portions of the face of a wearer of the goggles  10 . According to an exemplary embodiment, the head strap  40  includes a band (e.g., an elastic band, etc.) having length adjuster elements. The length adjuster elements may be configured to facilitate adjusting (e.g., extending, shortening, etc.) the size of the head strap  40  such that the goggles  10  may fit various sized heads. 
     According to an exemplary embodiment, the frame  20  is shaped to correspond with anatomical features of a wearer&#39;s face (e.g., cheeks, nose, forehead, etc.) to facilitate a proper fit of the goggles  10  when worn. As shown in  FIGS. 1 and 5 , the compressible member  50  is positioned along an interior of the frame  20  such that the compressible member  50  is in contact with a wearer&#39;s face when the goggles  10  are worn. The compressible member  50  may include an impact attenuating material and/or cushion material (e.g., expanded polyurethane (EPU) foam, expanded polypropylene (EPP) foam, expanded polyethylene (EPE) foam, polyolefin foam, etc.) to facilitate a snug fit and comfortable fit of the goggles  10  onto a wearer&#39;s face and/or mitigate impact forces encountered by the goggles  10  (e.g., from flying debris, etc.). 
     According to an exemplary embodiment, the frame  20  defines a cavity or opening configured receive the lens  30  such that the lens  30  is disposed across and/or within, and supported by the frame  20 . As shown in  FIGS. 1 and 5 , the lens  30  includes a unitary, arcuate lens that extends across the entire opening of the frame  20  (e.g., over both the left and right eyes of the wearer, from the right end  12  to the left end  14 , etc.). In an alternative embodiment, the lens  30  includes dual lenses, one positioned over each of the left and right eyes of the wearer. In some embodiments, the lens  30  is clear (e.g., substantially transparent, etc.). In other embodiments, the lens  30  includes a tinted and/or polarized coating to shade a wearer&#39;s eyes from sunlight, reduce glare, improve contrast, and/or enhance depth perception. The tinted and/or polarized coating may be various colors (e.g., black, yellow, blue, green, brown, gray, red, etc.). In some embodiments, the lens  30  includes a reflective coating (e.g., to prevent others from seeing where the wearer is looking, etc.). In some embodiments, the lens  30  is a prescription lens configured to enhance the vision of a wearer of the goggles  10 . In some embodiments, the lens  30  is or includes at least one of a toroidal lens and a spherical lens (e.g., when the lens cleansing system includes the wiper system  200 , preventing distortion in the vision of the wearer, etc.). In some embodiments, the lens  30  is a cylindrical lens. In other embodiments, the lens  30  is still otherwise shaped.

By way of example, a first upper cable may have both ends thereof embedded within the first side of the body  302  of the squeegee  296  and extend around the upper cable portion  252  of the right spindle  250  and a second upper cable may have both ends thereof embedded within the opposing second side of the body  302  of the squeegee  296  and extend around the upper cable portion  262  of the left spindle  260 . 
     As shown in  FIGS. 8-9 , the lower cable  294  includes a first end, shown as first end  295 , and an opposing second end, shown as second end  297 . The first end  295  is coupled to (e.g., attached to, embedded within, hard mounted to, etc.) the first side (e.g., the right side, etc.) of the body  302  of the squeegee  296  and the second end  293  is coupled to (e.g., attached to, embedded within, hard mounted to, etc.) the opposing second side (e.g., the left side, etc.) of the body  302  of the squeegee  296 . As shown in  FIGS. 5-9 , the lower cable  294  (e.g., the first end  295  thereof, etc.) extends from the first side of the squeegee  296 , enters the right canister  210  through the lower cable slot  234 , coils around the lower cable portion  256  of the right spindle  250 , exits the right canister  210  through the lower cable slot  234 , enters a second aperture, shown as lower through-hole  308 , defined by body  302  of the squeegee  296  through the first side of the body  302 , exits the lower through-hole  308  through the opposing second side of the body  302 , enters the left canister  220  through the lower cable slot  244 , coils around the lower cable portion  266  of the left spindle  260 , exits the left canister  220  through the lower cable slot  244 , and terminates within the second side of the squeegee  296  (e.g., the second end  297  thereof, etc.). The lower cable  294  may thereby forms a single, continuous cable (e.g., a monofilament cable, etc.) that extends around the right spindle  250  and the left spindle  260 , coupling the squeegee  296  thereto. In other embodiments, the lower cable  294  includes two or more portions or cables. By way of example, a first lower cable may have both ends thereof embedded within the first side of the body  302  of the squeegee  296  and extend around the lower cable portion  256  of the right spindle  250  and a second lower cable may have both ends thereof embedded within the opposing second side of the body  302  of the squeegee  296  and extend around the lower cable portion  266  of the left spindle  260 . 
     As shown in  FIGS. 5 and 7 , the actuation system  270  is coupled to the right canister  210  and includes a pull-cord including a pull-string  274  with a knob  272  attached to an end thereof. In other embodiments, the actuation system  270  is coupled to the left canister  220 . According to an exemplary embodiment, the actuation system  270  is configured to facilitate selectively cycling the upper cable  292  and the lower cable  294  between the right canister  210  and the left canister  220  such that the squeegee  296  selectively repositions across the front surface  32  of the lens  30  from the first position to the second position. As shown in  FIG. 7 , the pull-string  274  is coupled to (e.g., coiled around, etc.) the pull-cord portion  254  of the right spindle  250  with the end thereof extending through the pull-cord slot  236  such that the knob  272  is positioned outside of the right canister  210 . According to an exemplary embodiment, pulling the knob  272  causes the pull-string  274  to unwind from the right spindle  250 , thereby rotating the right spindle  250 . Such rotation of the right spindle  250  may cause the upper cable  292  and the lower cable  294  to selectively cycle between the right canister  210  and the left canister  220  such that the left spindle  260  also rotates, thereby causing the squeegee  296  to selectively reposition across the lens  30 . 
     As shown in  FIG. 6 , the wiper system  200  includes a resilient member, shown as rotational biasing element  280  (e.g., a torsional spring, a rotational spring, etc.), coupled to the left housing  222  (e.g., an end thereof attached to the left housing  222 , etc.) and the biasing portion  264  of the left spindle  260  (e.g., coiled around the biasing portion  264 , etc.). The rotational biasing element  280  may provide a biasing force that rotationally biases the left spindle  260  into a nominal position such that when the knob  272  is released, the squeegee  296  returns to the first position (e.g., the left end  14 , etc.). In other embodiments, the rotational biasing element  280  is coupled to the right spindle  250 . In still other embodiments, the wiper system  200  does not include the rotational biasing element  280  (e.g., in embodiments with an electric actuator, etc.). By way of example, the actuation system  270  may additionally or alternatively include an electric actuator positioned to rotate at least one of the right spindle  250  and the left spindle  260  (e.g., in response to wearer pressing a rotate button, etc.) to selectively rotate the spindles and thereby reposition the squeegee  296  across the lens  30 . 
     It is important to note that the construction and arrangement of the elements of the systems, methods, and/or apparatuses as shown in the exemplary embodiments are illustrative only.
