DETAILED DESCRIPTION OF THE INVENTION AND BEST MODE

[0027] While the invention is applicable to many types of animals, especially large animals and show and zoo animals of any size, it will be described here as applied to Equine animals, particularly to horses. First, it will be described as applied to horses, particularly show horses, race horses or other horses that will need top performance the next day or hours following treatment with the masks, goggles, or other equipment using the inventive concepts. However, it is applicable to any horses, other equine and other animals.

[0028] One type of mask according to the invention is shown in FIGS. 1 and 2 placed on a horse. The mask 1 is comprised of a flexible material, preferably an open weave cloth or polymer material like a 2.5 oz., 75 denier micromesh, breathable polyester stitched together in a well known normal manner. The mask 1 is comprised of blue blocking lens or sheet material like vinyl, polycarbonate, acrylic like Plexiglass, (PMMA), Polymethyl methacrylate, suspended over the eyes of the horse, preferably an amber colored 14 mil yellow colored polyvinyl chloride from LowBlueLights.com. If any of these materials do not contain a blue blocking material, a coating is applied to one face, the coating being colored amber or orange to block the blue light waves, preferably an amber colored, about 14 mil or heavier amber colored polyvinyl chloride like that from Tillman (the John Tillman Co.), or from thelLowbluelights.com website. FIG. 4 is a graph showing the blocking and filtering performance of the Tillman panels 2L and 2R in the mask. The visibility through 14 mil (0.0014 inch) thick Tillman blue light blocking material, and of 40 mil thick of material from the same source is shown in Photos 3 and 4 with the visibility being significantly better through the 14 mil material than through the 40 mil material, but the latter is also suitable for some applications. Suitable thicknesses of the blue light blocking material are from about 5 mil to about 50 mil with a preferred thickness being from about 10 mils to about 45 to 50 mils or thicker, and as used herein 14 mils was very suitable where the animal needed good visibility. This product can block about 100% of wavelengths of light form 400 nm to 510 nm, about 40% from 510 to 525 nanometers and partially blocks wavelengths from 525 nm to 575 nm. The graph in FIG. 6 shows the blocking of blue light and extending partially into the green light spectrum and the chart of FIG. 14 shows further blocking efficiency for this product.

[0029] The mask 1 is also comprised of openings 8L and 8R for the ears to pass through and having soft borders 6L and 6R to avoid irritating the ears, made preferably from a 13.5 oz. polyester double sided artic fleece. A top section 4 covering the forehead, preferably made from a 2.5 oz. 75 denier polyester Micro Mesh breathable material, an optional additional opening 5 for a forelock of mane to pass through, this opening having a soft border 7 like 6L and 6R. The mask 1 further comprises a front piece 14, preferably made from a 7.5 oz. cotton twill fabric with side pieces 12L and 12R (not shown) preferably made from the same material as the center panel 14. A lower piece 16 having a soft border 18 like the other soft borders 7 and 8L and 8R. Finally to hold the mask 1 onto the head of a horse a band 20 going under the horse's head and having a Velcro fastener 21 on its free end. This type of mask can also be used on a pony, mule, donkey, camel, and like animals.

[0030] The mask in FIG. 3 is similar to the mask in FIG. 1 but adds the optional opening 5 for a forelock of mane of the horse in the, top piece 4 having a border 7 around the edge of the opening 5. This border 7, as well as the other borders 6L, 6R, 10 and 18 are made preferably with a fleece material by folding this material over and sewing one edge to the top edge of the material forming the opening or the border, and sewing the other edge to the bottom edge of the material forming the opening or edge of the mask. FIG. 5 shows the opposite side of the mask shown in FIG. 1, showing how the strap 20 is sewed to the bottom panel 16 of the mask 1. The enclosed photos show an example of the mask described above.

[0031] FIG. 6 is a graph showing the blue light blocking performance of the blue light blocking material used in to cover the eye holes in the masks shown in FIGS. 1-5, also that can be used in goggles as shown in FIGS. 7-10. As shown, light waves having a wavelengths beginning about 400 nanometers (nm) and extending up to about 505-510 nm are totally blocked and then on up to about 520 nm are at least 80% blocked.

[0032] FIGS. 7-9 show a typical blue light set of goggles 51 of the invention for an animal, e.g. an equine like a horse, according to the invention. FIG. 7, a side view of a horse wearing a typical pair of goggles of the invention including a flexible transparent polycarbonate lens 32, a suitable lens material being described earlier with respect to the masks of the invention, surrounded by a felt piece 34 attached in any suitable manner to, preferably an open mesh screen fabric 50a having thereon a hook and loop fastener 44. A top piece 50b, preferably a black mesh screen fabric, contains an optional opening 37 for a forelock, is attached to a middle piece 20a and has an outer border 42. A lower piece 48 of the goggles 51 is preferably a 2.5 oz. 75 denier polyester mesh screen material. The lower piece 48 has a border 46 around its lower end. The hook and loop piece 44 attached to the middle piece 50a operates like the fastener described above on the masks of the invention. Border pieces 36, 40L, 40R, 42, and 46 are preferably a 13.5 oz. polyester double sided artic fleece surrounding ear openings 38 L and 38R formed like explained above in the description of the masks of the invention.

[0033] FIG. 10, an opposite side view of the goggles 51 shown in FIG. 7, has ear opening 38L having a soft border 40L in a top piece 50a, the latter having a soft border 52 formed from a 13.5 oz. double sided artic fleece and going around the rear of the goggles 51. A center front piece 36 borders top piece 50a. A frame 34 for the blue light blocking (blb) material 32 is attached to a center portion 50c, a suitable shape for the blue light blocking material 32 can be seen in plan view in FIG. 11. A frame opening 34 is held closed on the goggles 51 and 50c with a hook and loop 35, 47. The hook and loop is made of well-known brand, Velcro made by the Velcro company. It usually comprises two components; two lineal fabric strips that are attached (sewn or otherwise adhered together) to the opposing surfaces to be fastened. The first component has tiny hooks protruding from the fabric strip and the second fabric strap has tiny loops protruding for the tiny hooks to lock onto until pulled apart to separate. A lower piece 48, a black mesh screen material, is sewn to the middle piece 50c and has a border 46, same kind as the border 40L. The opening 37 in the mask is the opening created by unfastening the hook and loop fastener to allow the mask to be pulled open to remove, or replace, the blue blocking lens or material 32. The goggles 51 are secured onto the horse with the Velcro fastener 44.

[0034] There are several types of frames 33, 34 that are suitable for holding the blue light blocking (blb) material 32 as is apparent. The type described here is made using a Velcro fastener. Another type can be a blb material holder, goggles frame. It is preferably made by injection molding of a flexible, somewhat elastic polymer. It can have a groove in the surface surrounding the opening for the blb lens or material, the groove or slot being such that the outer edge of the lens can fit into it to hold the lens, or material snugly in place. The elasticity of the polymer frame allows the blb lens or material to be inserted into the groove or slot. The goggle frame can be any color but usually is black, or either the same or contrasting color to the fabric surrounding the goggle frame.

[0035] Also, another feature of the invention is that the blb material, lens like that used in the masks and goggles described herein can be a laminate, bonded together, or unbondedl and held together with another means like a Velcro frame or other type of frame, one layer being a transparent, preferably flexible, plastic material and the other layer being the blb layer. Using such a laminate a thinner blb material can be used with a thicker, transparent layer providing support and the thinner blb layer providing the blue light blocking and good visibility functions. Also, a more rigid transparent layer, either due to a more rigid material or a thicker layer or both, will also function to prevent the blb layer from being pushed into the animal's eye, or eyes, by wind or other cause. Using this type of multiple layer lens material with a flexible, but preferably semi-rigid transparent layer, allows a thinner, such as thin as 5 mil or thinner, blb material to be used in the invention where suitable to produce the blb function(s) desired. The transparent material will be next to the eyes if the two layers are not bonded together, but if bonded together the thin blb layer can be next to the eyes if desired, or an outer layer. Photo 5 shows an example of a 14 mil blb blocking material laid on top of a transparent plastic layer.

[0036] FIGS. 12 and 13 show another mask of the invention fastened onto a horse, FIG. 12 being a side view and FIG. 13 being a front view. This mask 55 has ear holes 66 L and 66R, each having a soft border 68L and 68R, in a mask material 64. The mask 55 also has two eye holes 58L and 58R having a blue light blocking material 59 sewn onto the mask material 64, such as a black mesh screen material, as shown, the mask 55 also has a soft back border 70 and a soft front border 56 like the soft borders on the other masks and goggles. This masks differs from earlier masks shown and described by having one or more features in, around, on or in the blue blocking material for keeping the blue blocking lens or material from being pushed into the horse's eyes by wind or some other force, in the case of the mask of FIGS. 12 and 13, with two eye protecting lens, material stabilizers, or restrainers, 60aL and 60bL, which are preferably low-density polyethylene plastic strips about 0.5 inch wide by about 2 inches long, used to prevent the blue light blocking material from being pushed into the horse's eyes by wind or other thing. Any other type of restrainer that doesn't irritate the horse can be used instead of restrainers 60aL and 60bL.

[0037] While soft borders on the masks of the invention, e.g. around the ear holes, around the optional forelock opening, around the lower and upper, or back, ends of the masks are optional, but preferred for endurance and comfort. Also, while the forelock opening is optional it is also usually preferred. Also, while the forelock opening is preferred, full ear covers are another option for any of the masks or goggles used.

[0038] This masks and the goggles of the invention can use different types of blue light blocking material instead of the amber vinyl from the Tillman Company, so long as they block more than at least 50% of the blue light waves having wave lengths of form about 400 to about 500 or 511 or 551 nanometers. FIG. 14 shows how one of the blue light blocking materials described herein performs in blocking blue light. Visibility is affected in many blb materials by the thickness of the blb material. While 14 mil thick material was preferred in the masks and goggles described above, much thinner and much thicker blb material can be used, e.g. up to at least 40 mils or thicker, especially for uses where visibility is not very important. However, for those uses where visibility is important, the thinner thicknesses are preferred. The photographs 1-5 show colored pictures of the 14 mil blb material used in the preferred masks described above and also show the type of visibility of this 14 mil blb material and the lesser visibility in the same material, but 40 mils thick.

EXAMPLE 1 METHOD

[0039] Shielding a horse's eyes using a blue light-blocking mask or goggles of the invention. The purpose of this test was to prevent the portion of the electromagnetic spectrum having wave lengths in the range of about 400 nm to at least about 510 nm from artificial lights, e.g. overhead lights, etc., such as in a building, from entering the animal's, e.g. a horse's, eyes, thus reducing its melatonin levels normally released by the pineal gland of the horse. A mask of the type shown in FIGS. 1 and 2, the eye holes covered with the amber colored polyvinyl membrane from the Tillman Company were put onto the horse at the onset of normal night cycle, e.g. sunset, and removed at or close to sunrise, at least two hours prior to any competition, to allow the stimulatory effects of the blue light wavelengths. Wearing the mask 1, allows melatonin to rise by preventing these inhibitory wavelengths of light from reaching the eyes of the horse. This has several functions including signaling the body of the horse that it is dark outside, i.e. night time, has a calming effect on the horse and prepares it for rest and sleep. Following this procedure, or one close in proximity will produce a higher performing horse the next day, one that is more alert, and having greater energy and endurance.

EXAMPLE 2 METHOD

[0040] This procedure and mask or goggles of the invention can also be used on animals, e.g. horses and others, that are suffering from international travel and/or jet lag. In these cases the mask or goggles can be used to mimic the photoperiod (light/dark cycle) they are used to and then gradually transition to the actual current new photoperiod.

EXAMPLE 3 METHOD

[0041] A mask or goggles of the invention is applied mid-summer to shorten estrous and speed up winter anestrous by increasing melatonin earlier in the light period, mimicking day lengths of October. Once they have been consistently exposed to short days for a period of days, they can then be exposed to long days using artificial light sources in November to be ready to breed the upcoming year. Melatonin level functions as the signal for female animals like equines, e.g. horses, to go in, or out, of estrous depending upon a series of increasing daylight cycles (brings on estrous depending upon a series of increasing daylight cycles) or a series of decreasing daylight cycles (brings on anestrous). Applying the mask 1-2 hours prior to sunset to shorten the perceived length of daylight can facilitate bringing the animal, e.g. a mare, into anestrous more quicklyas melatonin level also functions as the signal for animals like equines, mares, to become fertile for breeding earlier in the breeding period.

EXAMPLE 4 METHOD

[0042] A mask or goggles of the invention can also be used to treat head-shaker syndrome. For example, the mask or goggles as described above, is applied to a seasonal head-shaker syndrome afflicted horses. The mask is applied two hours before sunset to mimic a shorter photoperiod and removed close to sunrise the next morning.

EXAMPLE 5 METHOD

[0043] The mask can also be used for horses that are being treated in hospital situations while under lights at night. A mask or goggles of the invention is applied at sunset and removed at or close to sunrise. This allows the normal melatonin level to rise at night to better mimic the horse's normal circadian rhythm By allowing the horse to maintain normal bio-rhythms and elevations in melatonin, rest and recovery is enhanced while the horse is in a stressful environment.

[0044] Different embodiments employing the concept and teachings of the invention will be apparent and obvious to those of ordinary skill in this art and these embodiments are likewise intended to be within the scope of the claims. For example, another possible option is to create a double layer using the 14 mil 601 over a heavier clear vinyl before sewing together. The heavier clear vinyl is readily available off the shelf with low minimums. Another example, while the drawings and descriptions show applying the inventions to an equine animal like a horse, the inventions are also applicable to other animals, particularly to large animals needing better relaxation, recovery, performance, and the like. The inventor does not intend to abandon any disclosed inventions that are reasonably disclosed but do not appear to be literally claimed below, but rather intends those embodiments to be included in the broad claims either literally or as equivalents to the embodiments that are literally included.
