Abstract
Optical lenses are described and include a polymeric interference filter disposed on a curved polymeric substrate. The optical lens has an average light transmission of less than 2% across a band of blue light from 400 nm to at least 420 and up to 440 nm and substantially transmits blue light greater than 450 nm.
Claims26
An optical lens comprising:
- a curved polymeric substrate;
- a polymeric interference filter disposed on the curved polymeric substrate;
- wherein the optical lens has an average light transmission of less than 2% across a band of blue light having a short wavelength band edge of about 400 nm or less and a long wavelength band edge in a range from 420 to 440 nm and substantially transmits blue light having a wavelength that is 10 nm or greater than the long wavelength band edge.
An optical lens comprising:
- a curved polymeric substrate;
- a polymeric interference filter disposed on the curved polymeric substrate;
- wherein the optical lens has an average light transmission of less than 2% across a band of blue light from 400 nm to 420 nm and substantially transmits blue light greater than 430 nm.
An optical lens comprising:
- a curved polymeric substrate;
- a multilayer optical infrared reflecting film disposed on the curved polymeric substrate, the multilayer optical infrared reflecting film having a higher order harmonic reflecting a band of blue light in a range from 400 to 440 nm and substantially transmitting blue light greater than 450 nm.
An optical lens comprising:
- a spherically curved polymeric substrate;
- a polymeric bandstop filter disposed on the spherically curved polymeric substrate, the polymeric bandstop filter reflecting a band of yellow light having a FWHM of less than 40 nm and a 1% floor of the reflected band of yellow light having a width being greater than one half of the FWHM value.
An optical lens comprising:
- a spherically curved polymeric substrate;
- a polymeric interference filter disposed on the spherically curved polymeric substrate, the polymeric interference filter reflecting a band of visible light having a FWHM of less than 40 nm and a 1% floor of the reflected band of visible light having a width being greater than one half of the FWHM value.
