Health Fitness and Personal Care
Reviews and guides covering personal health and self-care devices: blood pressure monitors, fitness trackers, massage guns, blue light blocking glasses, water flossers and electric toothbrushes for braces.
Blue light glasses have their own guide because the marketing claims behind them run well ahead of the evidence — a Cochrane review of 17 randomised trials found no clear benefit for eye strain or macular protection, and rated the evidence for better sleep as very low certainty. The guide covers what's actually been shown rather than repeating the packaging claims, and the review applies that same more grounded standard when comparing specific pairs.
