Gunnar Intercept Onyx Gaming Glasses Amber Lens

Why it's worth it

The Intercept is the rare pair that tells you exactly what it filters at the 450nm peak instead of making a vague claim. At 33 grams with a wraparound frame, it's light enough for an eight-hour shift and blocks glare coming in from the sides.

Gunnar is the only major brand here that publishes a verified number. Most blue light glasses claim a percentage with nothing behind it. Gunnar's lenses are built to ANSI Z87.1 and the company reports its Blue Light Protection Factor at the 450nm peak — the band that actually matters for screens. All About Vision puts the critical range at 415 to 455nm. You don't have to take the marketing on faith, which is more than you can say for most of this category.

The frame weighs 33 grams, and you notice. Owners who wear these for eight-hour shifts and then game afterward consistently say the glasses stop registering after the first hour. The wrap shape does something the flat frames don't: it cuts the light coming in from a window or an overhead fixture at the edge of your vision. If you sit near a window or under office fluorescents, that peripheral glare is a real part of why your eyes hurt.
