Abstract: Method, device (100) and system (200) for detection and quantification of the variation of eye damage caused by the blue and violet light of the visible spectrum comprising the steps of detecting the incident radiation on an individual's visual system; calculating the incident radiation within the range between 380 and 500 nm; establishing at least one threshold of incident radiation within said range; detecting if at least one threshold established for said range has been exceeded; warning of the excess of at least one threshold; measuring the exposure time to incident radiation; and inferring in the different ocular structures of an individual the effect of incident radiation and warning of such effect.

Abstract: The subject of the invention is a covering filtering material for protecting eyes which are healthy, pseudo-aphakic (operated for cataracts) and/or having retinal degeneratiion under short wavelengths, which results from the application of a filter with yellow pigmentation on any covering, coating or screening material with the purpose of protecting the eyes from the short wavelengths of visible spectrum from 500 to 380 nm which cause retinal degeneration. By way of example, this element may be applied in materials intended for manufacturing awnings, parasols or insulating materials or protection screens of any type.

Abstract: Kit and method for the pre mortem in vitro detection of Alzheimer's disease The invention relates to a detection kit for Alzheimer's disease based on the vitro identification of the presence of biomarkers in the remains normally discarded after crystalline lens surgery. The kit can be used for the pre mortem detection of the disease, even before the appearance of clinical symptoms. Among the available biomarkers, the biomarker of choice is beta-amyloid peptide, for which several methods of sample processing and labelling for the presence of the biomarker may be used. Embodied in the invention is also the use of the crystalline lens remains discarded during surgery, often cataract surgery, to prepare a method for the in vitro pre mortem detection of Alzheimer's disease.

Abstract: The invention is a filtering, transparent device for preventing damage to healthy eyes and for the prophylaxis and therapy of pseudophakic eyes and/or eyes with macular and retinal neurodegeneration and is the result of applying a yellow filter to the transparent or translucent surface(s) of the visor of a protective helmet, to protect the eyes from the short wavelengths of the visible spectrum (500 to 380 nm). The invention avoids the difficulties and risks of existing ways of protecting healthy eyes or eyes subjected to cataract surgery, and improve the protection of eyes suffering retinal neurodegeneration, simply by applying a filter to the transparent or translucent surface(s) of the visor of any protective helmet. The invention consists of combining the transparent or translucent surface(s) of the visor of any protective helmet with a yellow filter that absorbs short wavelengths of light from 500 to 380 nm.

Abstract: A component with a yellow pigment that absorbs light wavelengths in the range 500 to 380 nm is provided for transparent or translucent components of a vehicle in order to protect healthy eyes, pseudophakic eyes, and eyes with macular and retinal degeneration from harmful ultraviolet rays. The component may be in the form of a filter that is applied on or within these transparent or translucent components of the vehicle.

Abstract: The object of the invention is a method and the corresponding device thereof for recognition of persons incorporating, as biometric constant and determinant for each individual, the irregularities of the map of the posterior surface of the cornea, being different in each individual. The invention is based on taking an image exclusively of the second ocular dioptric with the objective of determining the irregularities of the surface map thereof with respect to a standardised surface (sphere, ellipsoid, torus, etc.) and quantifying them, yielding a set of attributes characteristic of each person utilised as a system of authentication, that is to say utilising the variations and calculations carried out therewith as biometric minutiae. Taking an image is of proven safety insofar as it may be taken without any contraindication whatsoever and as many times as necessary.

Abstract: The invention relates to a person recognition method and device incorporating the anatomic location of the retina as a biometric constant, corresponding to the physiological location of the projection of the visual axis. More specifically, the invention relates to a person recognition method and a corresponding device incorporating the anatomic location of the retina as an exclusive discriminant biometric constant for each individual, corresponding to the physiological location of the visual axis, taking account of the physiological fixation disparity.

Abstract: A device is provided for the treatment and prophylaxis of healthy eyes, pseudoaphakic eyes and/or eyes suffering macular and retinal degeneration that comprises a yellow filter applied to a conventional illumination system to protect them from short wavelengths of the visible spectrum under 500 nm and preferably in the range of 350 nm to 500 nm. This device the difficulties and risks of existing ways of protecting eyes undergoing cataract surgery and prevents or improves the degeneration of healthy eyes and those suffering neurodegeneration by the simple application of a protective filter to any lighting system. Embodiments of the invention comprise combining a conventional light source with a conventional yellow filter that absorbs wavelengths of light shorter than 500 nm so that the filter completely covers the illumination source.

Abstract: The subject of the invention is a covering filtering material for protecting eyes which are healthy, pseudo-aphakic (operated for cataracts) and/or having retinal degeneration under shortwave lengths, which results from the application of a filter with yellow pigmentation on any covering, coating or screening material with the purpose of protecting the eyes from the shortwave lengths of visible spectrum from 500 to 380 nm which cause retinal degeneration. By way of example, this element may be applied in materials intended for manufacturing awnings, parasols or insulating materials or protection screens of any type.
