Biological cycle affecting goggles

A method as defined in claim, 7 in which the wavelengths are between 490 and 515 nm.

A method of avoiding the influence of light on the biological clock caused by the presence of full spectrum light during intervals unexpected by the human body comprising wearing contact lenses that substantially block light having wavelengths in a band of between about 480 and 530 nm. during exposure to said light while allowing visible light having wavelength outside and on each side said band to pass, while conducting normal activities using said visible light outside said band.

Contact lenses which can be worn to avoid the influence of light on the biological clock caused by the presence of full spectrum light during intervals unexpected by the human body comprising plastics which block visible light in a band having wavelengths of between 480 and 530 nm. and allowing visible light having wavelengths outside and on each side of said band to pass.

Flying goggles comprised of material which blocks light in a band having wavelengths of between about 480 and 520 nm. While allowing light having wavelengths outside and on each side of said band to pass.

Contact lenses comprised of material which blocks light in a band having wavelengths of between about 480 and 520 nm. while allowing light having wavelengths outside and on each side of said band to pass.

Reading glasses having lenses comprised of material which blocks visible light in a band having wavelengths of between about 480 and 530 nm. while allowing light having wavelengths outside and on each side of said band to pass, and includes light blocking side flaps for blocking light which has not passed through said material from entering the eye.

Driving glasses having lenses comprised of material which blocks light having wavelengths in a band of between about 480 and 530 nm. while allowing light having wavelengths outside and on each side of said band to pass, and includes light blocking side flaps for blocking light which has not passed through said material from entering the eye.
