1. Eyewear for providing therapeutic effects while being worn in sunlight, the eyewear comprising:
- a lens which allows two ranges of therapeutic wavelengths of light therethrough;
wherein an average light transmittance of the lens at the wavelength range of 460 nm to 510 nm is greater than the average light transmittance of the lens at the wavelength range of 400 nm to 450 nm for therapeutically affecting a wearer'"'"'s circadian rhythm;
wherein the average light transmittance of the lens for the range of 460-510 nm is greater than an average light transmittance for the range of 520 nm-560 nm, a maximum light transmittance within the range of 460 nm to 510 nm being at 470 nm to 495 nm to facilitate transmittance of a therapeutic portion of the blue light through the lens and a minimum light transmittance within the range of 540 nm to 600 nm being no less than 0.2 light transmittance of the lens starts to increase at or below 600 nm to facilitate transmittance of a full spectrum of red light through the lens, and an average light transmittance for the range between 650 nm to 850 nm is greater than an average overall light transmittance of the lens for perceptively darkening a scene viewed through the lens and stimulating cells of the wearer with red and near-infrared wavelengths of light.

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.
