Definitions
- the invention falls within the ophthalmology sector, within the preventive and therapeutic optical applications.
- the object of the invention is a filter covering material for the protection of healthy, pseudo-aphakic (cataract operated) eyes and / or with retinal degeneration against short wavelengths, which results from the application of a filter with Yellow pigmentation on any covering material, lining or screen in order to protect the eyes from the short wavelengths of the visible spectrum from 500 to 380 nm that produce retinal degeneration.
- the application of this element is indicated in the materials intended for the manufacture of awnings, sunshades or insulating materials or protective screens of any kind.
- Visual perception is the result of the response to visible radiation from 380 to 760 nm.
- solar radiation is the main risk for vision.
- the sun emits UV rays and IR radiation that are mostly absorbed by the atmosphere.
- the solar radiation that is transmitted through the atmosphere upon reaching the earth's surface consists of UV-B rays (from 230 to 300 nm), UV or UV-A rays (from 300 to 380 nm), visible light (from 380 to 760 nm) and IR rays (from 760 to 1400 nm).
- the eyes of a human in normal health freely transmit the IR rays and the majority of the visible spectrum to the retina but the cornea and the lens prevent the most reactive waves of the visible spectrum (UV-B rays and the light portion blue of the visible spectrum) reach the retina.
- the human lens changes its transmission characteristics as it ages, intensifying its yellow color and increasing its ability to filter UV rays and blue light. For this reason, the violet light ( ⁇ 400nm) is not transmitted in people over 65 and the transmission for the blue light (from 400 to 500 nm) decreases markedly.
- the retina self-protects the short wavelengths in two ways: with a heterogeneous distribution of the photoreceptors, so that in the macular depression there are no photoreceptors sensitive to blue light, and by the action of yellow pigments existing in the same area that also exert a protective action.
- AMD age-related macular degeneration
- the objective of the invention is, in general, the prevention and protection of the eyes against the absorption of blue and violet light, by means of a filter applied to cover, coating or screen materials. As mentioned, it is particularly useful in the case of pseudophakic subjects, to functionally compensate for the removal of protective pigments
- the invention is obtained as a result of the application in cover materials of a filter with yellow pigmentation that absorbs short wavelengths from 500 to 380 nm.
- cover materials of a filter with yellow pigmentation that absorbs short wavelengths from 500 to 380 nm.
- the application of this element is indicated in the materials intended for the manufacture of awnings, sunshades or insulating materials or protective screens of any kind.
- the element therefore combines three components:
- a mount or device to apply the filter to the material -
- Embodiment of the invention There are various embodiments of the invention, depending on the specific material where the filter is to be applied. Additionally, the embodiment of the present invention is illustrated by the following example of its application which is not, however, limiting its scope, since there are alternative forms and combinations for the manufacture of this element.
- a yellow filter of those available on the market is prepared, for example, the generic dye "Yellow 191"
- a support material or device available on the market is prepared for the application of the filter to the covering material, for example, the covering material of a plastic sunshade i -
- the yellow filter is applied on the face or faces of the material, so that it covers the desired light transmission area.
- cover, lining or screen materials and a yellow filter will allow any individual to protect healthy eyes from short wavelengths, to patients operated on cataracts with a transparent intraocular lens to correct the unprotected eye already operated
- the eyes with neurodegenerative processes improve and increase in this way the natural protection.
- filters without an application device and intraocular lenses are avoided.
