“…The crystalline lens of a 53-year-old person shows a transmission spectrum of 70% at 500nm and so, in theory, scotopic vision should actually be better with yellow IOLs in pseudophakic patients than in the phakic eye of a 53-year-old patient. 23,26…”

Yellow filters for the eye have been of interest to ophthalmologists and optometrists for the last 30 years. Certain fish species can change the colour of the cornea in response to the level of illumination and regulate the amount of short-wavelength light reaching the retina. A positive influence of yellow eye filters on reduction of chromatic aberration has been found in a fish eye model. Blue-light-filter (yellow) intraocular lenses (IOLs) were introduced for cataract surgery almost 20 years ago. The main advantage of yellow IOLs is thought to be the reduction of chromatic aberration under photopic conditions and protection of the retina from phototoxic short-wavelength light, especially in eyes at risk of age-related macular degeneration (AMD). This article highlights the importance of yellow IOLs for cataract surgery in terms of quality of vision and AMD protection.

“…To further complicate matters, what is considered visible light to humans will gradually change over decades because of reduced transmission through the crystalline lens. 12,13 For example, Sliney 10 describes being able to detect wavelengths as short as 310 nm during his twenties, but he can barely detect 400-nm wavelengths in his 70s. Thus, what is considered visible is greatly dependent upon an individual's age and their perceptual threshold.…”

“…Additionally, holding UV-blocking products to the 400 nm cutoff historically resulted in ophthalmic lenses that had a cosmetically undesirable yellow hue, 11 which was unappealing to consumers.
