Samsung s next-generation ultra-lightweight 3D Active Glasses are light-years ahead. When combined with Samsung 3D entertainment, 3D Active Glasses bring viewing to vivid life. Samsung s newest 3D Active Glasses offer even greater comfort over hours of viewing. Viewers who require corrective lenses can now order prescription lenses that clip on to the frames of the SSG-3300CR and SSG-3300GR; other models fit easily over existing glasses. Keep the 3D Active Glasses viewing-ready for family and friends with the Samsung Wireless Charging Hub (CY-SWC1000A) that recharges up to four pairs at a time.
