There has been much debate about the light transmission properties of various IOL optic designs. While most IOLs have a built-in UV blocker, only some IOLs provide a degree of visible light filtering. And even manufacturers who make the yellow-tinted IOLs offer them without a light filter. So which is better and is there a significant difference?
This is one of the best review papers about the IOLs which are designed to absorb short wavelength light. The paragraph highlighted in green is the summary paragraph.We can compare the absorption characteristics of IOLs with human crystalline lenses to see the differences in light transmission. Both IOL options are significantly better than the 70 year old human lens.

Dear Prof.Devgan
I have small suggestion regarding the video about Yellow tinted vs clear IOLs .
It’s already known and proven that there’s a third type of photoreceptors ,called intrinsically photosensitive retinal ganglion cells and their peak of sensitivity is exactly the blue light spectrum 470nm .
Research suggests the winter blues are triggered by specialized light-sensing cells in the retina that communicate directly with brain areas involved in mood.
With that in mind i don’t think there’s still a debate on yellow tinted vs clear lenses and such industry stunt should be left in the past , because there is obviously no feasibility to use filter which removes all one photoreceptor system from our patients .
Best regards
Merry Christmas and Happy new year
