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. An electronic device comprising:
a light transmission filter configured to:
block 5% to 50% transmission of blue light having a wavelength within a range of 400-500 nm such that energetic blue light photons are prevented from reaching a human eye, wherein the light transmission filter is a component of a first film, a first layer, or a first coating, and
provide an average light transmission of at least 80% across a wavelength range of 460-700 nm; and
a color balancing element configured to reduce, offset, neutralize, or compensate for an unwanted color effect of the light transmission filter such that a desired color of light transmitted through the electronic device reaches the human eye, wherein the color balancing element is a component of a second film, a second layer, or a second coating, and wherein the color balancing element is disposed on the light transmission filter or the light transmission filter is disposed on the color balancing element.
2. The electronic device of claim 1 , wherein the light transmission filter is a separate component from the color balancing element.
3. The electronic device of claim 1 , wherein the electronic device is a computer monitor.
4. The electronic device of claim 1 , wherein the electronic device is a television.
5. The electronic device of claim 1 , wherein the electronic device is a display device.
6. The electronic device of claim 1 , wherein the wavelength is within a range of 400-475 nm.
7. The electronic device of claim 1 , wherein the wavelength is within a range of 400-460 nm.
8. The electronic device of claim 1 , wherein the wavelength is within a range of 415-455 nm.
9. The electronic device of claim 1 , wherein the light transmission filter comprises an absorbing dye.
10. The electronic device of claim 1 , wherein the light transmission filter comprises a porphyrin dye.
11. The electronic device of claim 1 , wherein the color balancing element comprises a blue dye.
12. The electronic device of claim 1 , wherein the color balancing element comprises a mixture of red and green dyes.
13. The electronic device of claim 1 , wherein the light transmission filter is configured to block the blue light by absorption, reflection, interference, or a combination thereof.
14. The electronic device of claim 1 , wherein the light transmission filter is incorporated into a film of poly vinyl alcohol (PVA) or poly vinyl butyral (PVB).
15. The electronic device of claim 1 , wherein the light transmission filter comprises UVA and UVB inhibitors.
16. The electronic device of claim 1 , wherein the unwanted color effect is a yellow or an amber color effect.
17. The electronic device of claim 1 , wherein the light transmission filter is a blue light filter.
18. A display device comprising:
a blue light filter configured to:
block 5% to 50% of transmission of blue light having a wavelength within a range of 400-500 nm such that energetic blue light photons are prevented from reaching a human eye, wherein the blue light filter is a component of a first film, a first layer, or a first coating, and
provide an average light transmission of at least 80% across a wavelength range of 460-700 nm; and
a color balancing element configured to reduce, offset, neutralize, or compensate for a yellow or an amber color effect of the blue light filter such that a desired color of light transmitted through the display device reaches the human eye, wherein the color balancing element is a component of a second film, a second layer, or a second coating, and wherein the color balancing element is disposed on the blue light filter or the blue light filter is disposed on the color balancing element.
19. The display device of claim 18 , wherein the display device is a computer monitor.
20. The display device of claim 18 , wherein the display device is a television.
