Abstract: Provided are a lens composition that filters out and reduces transmittance of blue light and a lens formed of the composition. The lens composition includes: 40-50% thermoplastic material, 34-46% plasticizer, 2.6-4.4% quinophthalone, 2.1-3.6% perynone, 1.3-2.3% anthraquinone, and 0.48-0.82% luminophor. The lens is formed by having the composition mixed and subjected to pressing or injection molding so that the lens reduces the transmittance of blue light in the wavelength range of 380-550 nm to about 35-65% thereby reducing the harm caused thereby to human eyes.

Abstract: An improved 3-D shoe includes an outsole, an air pad, a midsole and an insole; wherein the outsole has a heel section and a sole section; a first air compartment containing air ducts is formed at the sole section; the midsole is placed above the outsole; the insole is placed above the midsole; the air pad is placed below the insole and above the heel section and provided with an air outlet. The improvement comprises a second air compartment, containing air ducts, being integrally formed at the heel section; a communicating duct being defined between the first air compartment and the second air compartment; and a ventilating hole being provided in one of the air ducts of the second air compartment at a lateral side of the outsole, such that the ambient air can enter the shoe through the ventilating hole to keep the user's foot fully dry.

Abstract: The insole has a number of flexible bulges on a first major surface, and a number of protruding ribs on a second major surface. The projections of the bulges fall within the regions bounded by the ribs. The bulges and their underlying bounding ribs therefore form a number of chambers. The insole further contains a number of through holes positioned between the ends of at least two ribs. The insole further contains a larger heel bulge provided on the first major surface in the heel section, and a concave on the second major surface, which is conducted to the other chambers via at least a duct.

Abstract: A shoe sole includes a bottom, an insole, and a midsole. The insole forms a plurality of air passages extending therethrough, and has a bottom face on which a plurality of first raised sections is formed to delimit a plurality of first air chambers. The midsole is positioned between the insole and the bottom and has a top face opposing the bottom face of the insole and forming a plurality of second raised sections that delimits a plurality of second air chambers, the second raised sections being configured to correspond in position to the first raised sections so that when the midsole is stacked on the insole, the first raised sections are respectively positioned on the second raised sections and the first air chambers respectively correspond to the second air chambers to form combine air chambers that each have an increased volume.

Abstract: A ventilating structure for a shoe is provided, which contains a duct member containing a number of air ducts communicating with a plurality of through holes at the sole's rim, a first pad member having a plurality of through holes on top of the duct member, a semi-spherical bubble member fixedly attached to the top of the first pad member covering at least a through hole of the first pad member directly above an air duct of the duct member, and a second pad member on top of the first pad member having a number of through holes and a bulged section accommodating the bubble member. As a user walks on a shoe of the invention, the bubble member, like a pump, undergoes intermittent compressions and releases by the user's foot, causing warm and humid air to be expelled out or fresh air to be drawn inside of the shoe quickly and periodically.

Abstract: The present invention relates to heat-resisting silicone materials containing inorganic ceramic hollow microspheres, which comprising an inorganic hollow microsphere substrate consisted of inorganic ceramic hollow microsphere, silicone rubber and other compounds, wherein the inorganic ceramic hollow microspheres with diameters of 80-100 ?m, and complex ceramic powders of nano-grade. The silicone rubber has heat-resisting temperature up to 450° C., so that the heat-resisting temperature of resultant silicone materials of the invention may be raised to 450° C. even higher. Furthermore, the heat energy can be converted to thermal radiation with the broad wavelength in frequency domain of about 2-80 ?m by the silicone materials of the invention.
