Somnr Gamma Ray Blue Light Blocking Glasses vs Zenni Optical Blokz

The Somnr Gamma Ray is the cheaper-feeling pick: a lightweight TR90 frame with polycarbonate lenses that claim to cut about 95% of blue light, and 306 ratings average 4.3. The Zenni Blokz is the more finished product: a full-rim frame with anti-reflective coating, 100% UVA/UVB protection and blocking up to 420 nm, backed by a brand that builds prescription eyewear. Buy the Somnr for casual screen use and a spare pair; buy the Blokz if you want a better-coated lens and a frame you can wear out.

• Choose the Somnr Gamma Ray if you want a light, simple pair for TV and phone screens and don't need a prescription or a fashion frame.
• Choose the Zenni Blokz if you want anti-reflective coating, full UV protection and a sturdier full-rim frame from an eyewear specialist.
