Zenni Optical Blokz vs Gunnar Enigma Onyx

The Zenni Blokz is the simpler, lighter buy for a woman who wants a square business frame with full UV protection and blue light filtering built into the lens. The Gunnar Enigma is the stronger pick if you need prescription lenses, progressive support, or a choice of tint and focus levels. Zenni's frames are widely seen as good value but basic in build, while Gunnar owners tend to praise the lens tint and frame durability and complain about the narrower fit.

• Choose the Zenni Blokz if you want a square full-rim frame with blue light blocking to 420 nm and full UVA/UVB protection, and you do not need prescription lenses.
• Choose the Gunnar Enigma if you need prescription lenses up to plus or minus 5.00, progressive eligibility, or a choice of amber, clear or sun tints.
