As Seen on TV, Tac Glasses by Bell + Howell are military-inspired, polarized sports glasses for men and women.Tac Glasses block harmful UV rays and glare, improving visibility against reflective surfaces like asphalt covered roads, snow, and sand. Their light filtering technology improves visual clarity, even under low light conditions, while sharpening colors and edges of objects, and the lenses are corrosion proof against alkaline conditions such as exposure to ocean spray. Featuring extra durable black matte frames with rust proof screws, Tac Glasses provide the aesthetic design, construction, and functionality of costly eyewear for a fraction of the cost!
