    • A method and system is provided for controlling the intensity and wavelength of light that is perceived by a user to achieve optimal contrasts when viewing medical images. A medical image reviewing system may include at least one medical image displaying monitor and a light-filtering optical eyewear. The light-filtering optical eyewear may include an eyewear frame, the eyewear frame including a first temple, a second temple, and a lens frame, the lens frame being centrally connected between the first temple and the second temple. The light-filtering optical eyewear may further include a first ambient light shield, the first ambient light shield being connected along the first temple. The light-filtering optical eyewear may further include a second ambient light shield, the second ambient light shield being connected along the second temple. The light-filtering optical eyewear may further include a light-filtering lens assembly configured to optimize the contrasts of the medical images being viewed by the user and maintain activation of rods in the eyes of the user for low light level viewing by the user.
