Blue Light Blocking Glasses Rectangle Full Rim vs Gunnar Optiks Vertex Blue Light Blocking Glasses

Buy the Gunnar Vertex if you want a proven screen-glasses brand with a fixed nose ridge, dual-sided anti-reflective coating and a stated one-year warranty. Buy the rectangle 201974 if you want a photochromic lens that darkens outdoors and a speckled tortoise acetate look. The Gunnar has the more established optical reputation and sturdier hinge hardware; the 201974 is the more versatile single pair for indoor and outdoor wear.

• Choose the rectangle 201974 if you want one pair that blocks blue light at the desk and darkens into sunglasses outside, in a tortoise acetate frame.
• Choose the Gunnar Vertex if you want a dedicated screen pair from a brand known for computer eyewear, with anti-reflective coating on both lens faces and a fixed nose ridge.
