Authors' conclusions
This systematic review found that blue‐light filtering spectacle lenses may not attenuate symptoms of eye strain with computer use, over a short‐term follow‐up period, compared to non‐blue‐light filtering lenses. Further, this review found no clinically meaningful difference in changes to CFF with blue‐light filtering lenses compared to non‐blue‐light filtering lenses. Based on the current best available evidence, there is probably little or no effect of blue‐light filtering lenses on BCVA compared with non‐blue‐light filtering lenses. Potential effects on sleep quality were also indeterminate, with included trials reporting mixed outcomes among heterogeneous study populations. There was no evidence from RCT publications relating to the outcomes of contrast sensitivity, colour discrimination, discomfort glare, macular health, serum melatonin levels, or overall patient visual satisfaction. Future high‐quality randomised trials are required to define more clearly the effects of blue‐light filtering lenses on visual performance, macular health and sleep, in adult populations.
I recently bought new glasses, and they have a blue light filter. I wasn't very keen on it, because it distorts colors a bit with a yellow tint, but the optician insisted on it.
But it might be that it's a pointless feature with no real world advantages.
Although this study was peer-reviewed, it still requires more studies to further validate it's findings.
So the question is for our Gaf colleagues: do you use glasses with blue light filter? And what do you think of it?
