Method and device for preventing alterations in circadian rhythm
First Claim
1. A method of maintaining the circadian rhythm of a subject exposed to light at night comprising selectively substantially blocking retinal exposure of the subject to light of wavelengths less than about 490 nm during the night, wherein selectively substantially blocking comprises transmitting less than 40 percent of the blocked wavelengths of light, while allowing transmission of more than 40 percent of non-blocked wavelengths of light and wherein the method inhibits melatonin suppression by light at night.

Abstract
A method of maintaining circadian rhythm of a subject comprising selectively substantially blocking retinal exposure of the subject to light having a wavelength shorter than a specified wavelength during the night, and an apparatus for carrying out the claimed method comprising an optical filter that selectively at least substantially blocks light having a wavelength shorter than the specified wavelength.
