Preparations are disclosed containing the 3R-3'R stereoisomer of zeaxanthin as a sole detectable isomer, packaged for oral ingestion by humans as a therapeutic drug or nutritional supplement. Zeaxanthin is a yellow carotenoid pigment found in the macula (in the center of the human retina), which helps protect retinal cells against phototoxic damage. The pure R-R stereoisomer can be prepared by fermenting cells, such as Flavobacterium multivorum (ATCC 55238), which do not create any detectable quantity of the undesired and potentially toxic S-S or S-R isomers, and which do not synthesize any other carotenoids. The R-R isomer can be concentrated, in large quantities and at low cost, into a viscous oily fluid containing about 5 to 20% zeaxanthin, by means of a simple solvent extraction process. This oily fluid can be mixed with a carrier such as vegetable oil and enclosed within a digestible capsule, comparable to a conventional capsule containing Vitamin E. Alternately, a zeaxanthin fluid can be added to various types of foods, such as margarine, dairy products, syrup, cookie dough, and certain types of meat preparations which are not subjected to harsh cooking. Additional purification steps can also be used to purify zeaxanthin to a granular or powdered state which contains nearly pure zeaxanthin. Such processing can be used to create formulations such as ingestible tablets, and particulate formulations that can be added to soups, salads, drinks, or other foods. Preferred stabilizers and anti-oxidants are also disclosed herein. When consumed by humans in any of these modes, the purified R-R stereoisomer of zeaxanthin can help treat and prevent macular degeneration, one of the leading causes of blindness and vision loss, especially among the elderly.

The invention relates to functional grease composition which is rich in omega-3 unsaturated fatty acid and xanthophyll. The functional grease composition disclosed by the invention can effectively protect eyes from being damaged by light rays, slow down the aging of the eyes, prevent the eyes from generating pathological changes, strengthen the brain and improve the memory.

A screen protection sheet with a function of blue light filtering comprises a PET film (bi-direction extensible polyester film); an anti-glare layer (or a surface hard-coating layer) on an upper surface of the PET film; an adhesive layer on a lower side of the PET film. A blue light filtering layer is installed on an upper side of the anti-glare layer (or the surface hard-coating layer) or between the film and the adhesive layer, or on an upper side of the anti-glare layer (or the surface hard-coating layer) and a second blue light filtering layer is installed between the film and the adhesive layer. The screen protection sheet may also be formed by a PET film; an anti-glare layer on a lower side of the film; an adhesive layer on a lower side of the anti-glare layer; and a blue light filtering layer on an upper side of the film.

A method of vacuum evaporation coating process that effectively block blue light and infra red light on optical lenses includes five steps. Step one is to provide a lens substrate. Step two is via vacuum evaporation coating process to evaporate silicon dioxide layer on the surface of said lens substrate. Step three is to use the vacuum evaporation coating process to evaporate zirconium dioxide layer on top of the silicon dioxide layer. Step four is to repeat step two and three to coat a plurality of silicon dioxide layers and zirconium dioxide layers. Step five is to repeat step two thus forming a multilayer stacking structure. Therefore, said stacking structure can block partial blue light and infrared light on optical lenses to achieve the effect of eye protection.

The invention relates to an anti-blue-ray resin lens with the refraction index of 1.56. The anti-blue-ray resin lens with the refraction index of 1.56 comprises a resin substrate with the refraction index of 1.56; the resin substrate is dip-coated with a hardened film; a first SiO2 film, a ZrO2 film, a second SiO2 film, a Ti2O3 film, an In2O3 film and a third SiO2 film are deposited on the surface of the hardened film in sequence. According to the resin lens disclosed by the invention, the effect of filtering blue rays with the wavelength of 400 to 500 nm can reach 40 to 50 percent; blue ray radiation can be filtered effectively; sharp pain, soreness and swelling of eyes can be reduced; eye dryness and eye fatigue can be reduced; cataract and macular degeneration can be prevented.

The invention discloses a preparation method for nutrient five-cereal coarse food. The nutrient five-cereal coarse food is prepared by the following raw materials in parts by mass: 5-15 parts of rice,5-15 parts of wheat, 5-15 parts of beans, 5-15 parts of corn, 5-15 parts of potatoes, 5-20 parts of sesame, 0.5-1 part of a spice agent, 1-2 parts of a flavoring agent, 40-60 parts of water, and 1-5parts of salad oil. The nutrient five-cereal coarse food is capable of, through adding the rice, the wheat, the beans, the corn, the potatoes and the sesame, supplementing nutrients to many symptoms well, has the prevention and treatment effect, and has a great promotion value.
