Abstract

The embodiments disclosed herein relate to a transparent material to provide protection to a person'"'"'s eyes from harmful wavelengths of the light spectrum, overall visual comfort, or improved vision such as color enhancement, target recognition and other functions, while selectively transmitting more of certain wavelengths of the light spectrum that have a therapeutic benefit such as healing or general mood modifier. The transparent material may be a lens or a shield which is disposed in front of the wearer'"'"'s eyes.

Claims

1. An eyewear comprising:

a lens or shield which selectively allows therapeutic wavelengths of light therethrough while blocking harmful wavelengths of light.

2. The eyewear of claim 1 wherein an average light transmittance of the lens or shield at a wavelength range of 450 nm to 510 nm is substantially greater than an average light transmittance of the lens or shield at a wavelength range of 400 nm to 450 nm.

3. The eyewear of claim 2 wherein the average light transmittance of the lens or shield at the wavelength range of 450 nm to 510 nm is 2 or more times the average light transmittance of the lens or shield at the wavelength range of 400 nm to 45 nm.

4. The eyewear of claim 1 wherein light transmittance through the lens or shield increases beginning at or about 600 nm and an average light transmittance in the range of 650 nm to 850 nm is about 2 or more times an overall lens Tv of the lens or shield.

5. The eyewear of claim 2 wherein the light transmittance of the lens at 450-510 nm is 20% or more than an average light transmittance for the range of 500 nm-600 nm, and light transmittance through the lens or shield increases beginning at or about 600 nm and an average light transmittance for the range between 650 nm to 850 nm is 2 or more times an average overall light transmittance of the lens or shield.

6. The eyewear of claim 5 wherein the lens or shield blocks substantially all wavelengths below 400 nm.

7. The eyewear of claim 6 wherein light transmittance through the lens or shield increases as the wavelength increases from 400 nm to 450 nm.

8. The eyewear of claim 5 wherein the light transmittance has a relative maximum at 460 nm to 490 nm within the range of 450 nm to 510 nm.

9. The eyewear of claim 8 wherein the light transmittance has a relative maximum at 470 nm to 480 nm within the range of 450 nm to 510 nm.

10. The eyewear of claim 5 wherein light transmittance is substantially attenuated in the range of 510 nm-600 nm with a minimum transmittance within the range of 510 nm to 600 nm no less than 0.2 Tv transmittance.

11. The eyewear of claim 5 wherein an overall light transmittance value of the lens or shield is 8% to 15%.

12. The eyewear of claim 5 wherein an overall light transmittance value of the lens or shield is 16% to 25%.

13. The eyewear of claim 5 wherein an overall light transmittance value of the lens or shield is 25% to 50%.
