Zenni Optical Blokz vs Firmoo Classic Square Blue Light Glasses

Both are low-cost blue-light glasses, so the choice comes down to fit and lens quality. The Zenni Blokz has a wider 132 mm frame, a 53 mm lens, anti-reflective coating and full UVA/UVB protection, which suits smaller-to-average faces and long screen days. The Firmoo is lighter at 11 g with a TR90 frame and claims 99% blocking across 380-450 nm, but it has no stated anti-reflective coating or UV rating. Owners of both report the coatings wear over time; the Zenni's AR coat tends to hold up better.

• Choose the Zenni Blokz if you want a wider frame, anti-reflective coating and stated full UV protection for all-day computer work.
• Choose the Firmoo if you want the lightest frame and the broadest stated blue-light blocking range at a low entry point.
