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. This invention avoids the difficulties and risks of the existing techniques for providing this protection for healthy and cataract-operated eyes and for improving protection for eyes undergoing neurodegenerative processes, achieving this with the simple application of a filter to common covering, coating or screening materials, thereby furnishing additional protection against neurodegenerative agents found in light (short wavelengths). ## Claims ### Claim 1 Covering material for the protection and therapy of healthy eyes from short wavelengths, said covering being the result of applying a yellow pigmentation filter that absorbs short wavelengths from 500 to 380 nm on sun-covering materials wherein the filter does not absorb other wavelengths. ### Claim 2 (depends on 1) Material for the protection of healthy eyes from short wavelengths according to claim 1, comprising a yellow pigmentation filter appropriate for use with the application material or materials. ### Claim 3 (depends on 1) Material for the protection of healthy eyes from short wavelengths according to claim 1, that comprises one or more covering, coating or screening materials. ### Claim 4 (depends on 1) Material for the protection of the eyes from short wavelengths according to claim 1, in which the materials are those intended for manufacturing awnings, parasols or insulating materials or protection screens of any type. ### Claim 5 (depends on 1) Material according to claim 1, characterised by its filtering quality. ### Claim 6 Covering material for the protection and therapy of pseudo-aphakic eyes from short wavelengths, characterised in that said material results from the application of a filter with yellow pigmentation that absorbs short wavelengths from 500 to 380 nm onto sun-covering materials wherein the filter does not absorb other wavelengths. ### Claim 7 (depends on 6) Therapeutic and prophylactic material for pseudo-aphakic eyes according to claim 6, that comprises a yellow pigmentation filter appropriate for use with the application material or materials. ### Claim 8 (depends on 6) Therapeutic and prophylactic material for pseudo-aphakic eyes according to claim 6 that comprises one or more of covering, coating or screening materials. ### Claim 9 (depends on 6) Therapeutic and prophylactic material for pseudo-aphakic eyes according to claim 6, in which the materials are intended for manufacturing awnings, parasols or insulating materials or protection screens of any type. ### Claim 10 (depends on 6) Material according to claim 6, characterised by its filtering quality. ### Claim 11 Covering material for the protection and therapy of eyes undergoing retinal neurodegenerative processes from short wavelengths, characterised in that said material results from the application of a yellow pigmentation filter that absorbs short wavelengths from 500 to 380 nm onto sun-covering materials wherein the filter does not absorb other wavelengths. ### Claim 12 (depends on 11) Therapeutic and prophylactic material for eyes undergoing retinal neurodegenerative processes according to claim 11, that comprises a yellow pigmentation filter appropriate for use with the application material or materials. ### Claim 13 (depends on 11) Therapeutic and prophylactic material for eyes undergoing retinal neurodegenerative processes according to claim 11, that comprises one or more covering, coating or screening materials. ### Claim 14 (depends on 11) Therapeutic and prophylactic material for eyes undergoing retinal neurodegenerative processes according to claim 11, in which the materials are intended for manufacturing awnings, parasols or insulating materials or protection screens of any type. ### Claim 15 (depends on 11) Material according to claim 11, characterised by its filtering quality.
