Invisible rays that are part of the energy that comes from the sun. Ultraviolet A radiation also comes from sun lamps and tanning beds. Ultraviolet A radiation may cause premature aging of the skin and skin cancer. It may also cause problems with the eyes and the immune system. Skin specialists recommend that people use sunscreens that protect the skin from ultraviolet radiation. In medicine, ultraviolet A radiation also comes from special lamps or a laser and is used to treat certain skin conditions such as psoriasis, vitiligo, and skin tumors of cutaneous T-cell lymphoma.
Device for oral UV photo-therapy
Skin disorders such as, for example, atopic dermatitis, dyshidrosis, eczema, lichen planus, psoriasis, and vitiligo, are treated by applying high doses of ultraviolet light to diseased regions of a patient's skin. The dosage exceeds 1 MED as determined for the particular patient and may range from about 1 MED to about 20 MED or higher. The ultraviolet light has a wavelength within the range of about 295 nanometers to about 320 nanometers. High doses of ultraviolet light are preferably restricted to diseased tissue areas. A specialized handpiece provides a beam profile especially suitable for application of controlled doses. A specialized delivery device is useful for UV treatment of tissue within the mouth.

Treatment of skin disorders with UV light and cooling
Skin disorders such as, for example, atopic dermatitis, dyshidrosis, eczema, lichen planus, psoriasis, and vitiligo, are treated by applying high doses of ultraviolet light to diseased regions of a patients skin. The dosage employed exceeds 1 MED, an MED being determined for the particular patient being treated, and may range from about 1 MED to about 20 MED or higher. The ultraviolet light has a wavelength within the range of between about 295 nanometers to about 320 nanometers and preferably is between about 300 nanometers and about 310 nanometers. High doses of ultraviolet light are restricted to diseased tissue areas so as to avoid risk of detrimental side affects in healthy skin, which is more susceptible to damage from UV light. Cooling the skin prior to and / or while exposing the skin to the UV light can be used to minimize tissue damage resulting from exposure to the UV light. Higher doses of UV light can therefore be employed without injurious affects.

Method of stabilizing human eye tissue by reaction with nitrite and related agents such as nitro compounds
A method for stabilizing collagenous eye tissues by nitrite and nitroalcohol treatment. The topical stiffening agent contains sodium nitrite or a nitroalcohol in a buffered balanced salt solution and can be applied to the surface of the eye on a daily basis for a prolonged period. Application of the solution results in progressive stabilization of the corneal and scleral tissues through non-enzymatic cross-linking of collagen fibers. The compounds can penetrate into the corneal stroma without the need to remove the corneal epithelium. In addition, ultraviolet light is not needed to activate the cross-linking process. The resulting stabilization of corneal and scleral tissues can prevent future alterations in corneal curvature and has utility in diseases such as keratoconus, keratectasia, progressive myopia, and glaucoma.

Solar blind-UVC photochromic detector and method for calibration
The present invention relates to an ultraviolet radiation detector in general and more specifically to a solar blind ultraviolet radiation detector; that is, a detector insensitive to the radiation of sunlight reaching the earth's surface but sensitive to UVC wavelengths in the spectrum, defined as the interval 200 nm-280 nm. The solar blind detector is base on the use of photochromic compounds in conjunction with ultraviolet wavelength-selective chemical blocks and their incorporation into optically clear polymer matrices. The photochromic compound is selected from the group comprising spiropyran molecules spirooxazine molecules and chromene derivatives. Applications for such device are as numerous as the sources of UVC radiation. An obvious use for such Solar Blind UVC detector is monitoring the output of UVC sources used in the decontamination of water and air (water treatment and air purification) and for sterilization of medical instruments.
