High energy visible light filter systems with yellowness index values
The present invention relates to ophthalmic and non-ophthalmic systems with blue light filtering and Yellowness Index ranges. UV and IR filtering are also included. Industrial applications are also outlined in the invention.
1. A non-ophthalmic electronic device comprising:
a filter comprising a film that selectively inhibits 5 to 50% of light transmission at every wavelength in a 430+/−20 nm range and has an average light transmission of at least 80% in a group of wavelengths greater than 460 nm;
wherein the film comprises a porphyrin dye, or a porphyrin derivative, having a Soret band, and
wherein the light transmitted through the filter impinges directly on a human retina.
2. The non-ophthalmic electronic device of claim 1 , wherein the filter inhibits 5-60% of light having a wavelength of 430+/20 nm.
3. The non-ophthalmic electronic device of claim 1 , wherein the filter inhibits 5-90% of light having a wavelength of 430+/20 nm.
4. The non-ophthalmic electronic device of claim 1 , wherein the porphyrin dye or porphyrin derivative is selected from the group consisting of: diprotonated-tetraphenylporphyrin; magnesium octaethylporphyrin; magnesium octaethylporphyrin (MgOEP); magnesium tetramesitylporphyrin (MgTMP); magnesium tetraphenylporphyrin (MgTPP); octaethylporphyrin; phthalocyanine (Pc); porphin; tetra-t-butylazaporphine; tetrakis(2,6-dichlorphenyl)porphyrin; tetrakis(o-aminophenyl)porphyrin; tetramesitylporphyrin (TMP); tetraphenylporphyrin (TPP); zinc octaethylporphyrin (ZnOEP); zinc tetramesitylporphyrin (ZnTMP); zinc tetramesitylporphyrin radical cation; and zinc tetrapheynlporphyrin (ZnTPP).
5. The non-ophthalmic electronic device of claim 1 , wherein the filter further comprises a synthetic or non-synthetic antioxidant.
6. The non-ophthalmic electronic device of claim 1 , wherein the filter further comprises a natural or synthetic or derivative of a carotenoid.
7. The non-ophthalmic electronic device of claim 1 , wherein the filter comprises UVA and UVB inhibitors.
8. The non-ophthalmic electronic device of claim 1 , wherein the filter is a synthetic or non-synthetic pigment.
9. The non-ophthalmic electronic device of claim 1 , further comprising infra-red radiation inhibitors.
10. The non-ophthalmic electronic device of claim 1 , wherein the filter inhibits 5-90% of light having a wavelength of 430+/−10 nm.
11. The non-ophthalmic electronic device of claim 1 , wherein the filter is incorporated into PVA or PVB.
12. The non-ophthalmic electronic device of claim 1 , wherein the filter inhibits light by absorption, reflection, interference or any combination thereof.
13. The non-ophthalmic electronic device of claim 1 , wherein the filter further comprises lutein, zeaxanthin, melanin or any combination thereof.
14. The non-ophthalmic electronic device of claim 1 , wherein the filter has a yellowness index of not more than 35.0.
15. A non-ophthalmic electronic device comprising:
a filter comprising a film that selectively inhibits 5 to 50% of incident light transmission at every wavelength in a 430+/−20 nm range,
wherein the average transmission of light from the non-ophthalmic electronic device is at least 80% in a wavelength range of 400-700 nm,
wherein the filter comprises a porphyrin dye, or a porphyrin derivative having a Soret band, and
wherein the light transmitted through the filter impinges directly on a human retina.
16. A system disposed on a non-ophthalmic electronic device comprising:
a filter comprising a film that selectively inhibits 5 to 50% of incident light transmission at every wavelength in a 430+/−20 nm range,
wherein the average transmission of light from the system is at least 80% in a wavelength range of 400-700 nm,
wherein the filter comprises a porphyrin dye, or a porphyrin derivative having a Soret band, and
wherein the light transmitted through the filter impinges directly on a human retina.
