Relative effectiveness of a blue light-filtering intraocular lens for photoentrainment of the circadian rhythm

The tinted IOL was significantly more effective for photoentrainment of the circadian rhythm with newer action spectra. The computational results suggest that the effectiveness of the tinted IOL in 60- to 85-year-old patients would be within +6% to −13% of that in 30 to 39 year olds. Both tinted and untinted IOLs are expected to be effective for melatonin suppression under average household illumination.
