Dear Editor
I appreciate Dr Van Gelder’s thoughtful comments regarding the potential consequences of a UV+blue light absorbing intraocular lens (IOL) on circadian rhythmicity.[1] I agree that the clinical importance of retinal ganglion photoreceptors is currently unknown and that decreasing the amount of blue light reaching them might affect their function. Conversely, if photosensitive ganglia respond to circadia...

Dear Editor
Drs Mainster and Sparrow have provided an excellent perspective on the relative merits and difficulties of extending IOL absorption into the blue portion of the spectrum.[1]
However, they have not considered an unintentional consequence of blockage of the blue portion of the spectrum: reducing the activity of intrinsically photosensitive retinal ganglion cells.[2, 3] These cells subserve se...
