I think it's important to not make assertions that something is definitely true when we don't know that yet.) I explain that we get exposed to blue light outside in the sunshine too. I tell them that there is evidence to suggest that blue light can make your eyes feel more strained or tired, due to those light rays falling short of the retina. I also remind them that any time you are staring at a screen, be it your phone or computer, you tend to blink less, which can also contribute to eye tiredness and strain and dry eye, so it is important to take breaks to look away and blink.
I have had a patient tell me that they believe the blue blocker helps prevent migraines for them. Maybe that's true or maybe that's the placebo effect. Who knows.
If they ask about blue blocker and really want it, I just put them in Crizal Prevencia or another ar w/ blue blocker, or if they are already adding Transitions to their lenses, I explain that it already blocks out most of the HEV light so it's redundant to add blue blocker. I don't really push blue-blocker as a separate lens option, but if a patient brings it up or complains about digital eye strain, I will mention it but with all the disclaimers I mentioned above.
