I have a set of Ra Optics because they were highly recommended. I know Dr. Kruse mentions Lucia Optics as well. And recently, we sprung for a red light lamp from the guys at Elios… and they also have a good set at https://shop.evolutamente.it/ They even come in clip-on form, which is a budget-friendly way to mitigate blue light if you use prescription and don’t want to get a new set every time your prescription changes/drifts.
