GUNNAR Vertex Blue Light Glasses (Clear Lens, Onyx)

GUNNAR Vertex blue-light gaming glasses with clear lens and 35–98% blue-light filtering claim (manufacturer specification). Frame: lightweight plastic in Onyx colorway, designed for all-day screen use. Coatings: anti-reflective and blue-light-blocking lens treatment. Fit: standard adult sizing. Marketed to gamers, office workers, and students seeking to reduce screen glare and eye strain during extended digital use.

Important note: Clinical evidence that blue-light filtering reduces eye strain or improves sleep is limited and actively debated by major optometry bodies (e.g., American Academy of Ophthalmology). GUNNAR's stated filtering strength is a measurable lens property; user reports of reduced glare and comfort are common, but health benefits remain unproven. The Vertex sits in GUNNAR's mid-tier line—established brand trust, solid reviews, and moderate price point.
