Elvex RX-200 is Elvex's second generation of bifocal safety glasses, and the company has combined the requirement for bifocal lenses with the desire for stylish, lightweight and comfortable glasses. RX-200 uses two base six lenses, in a contemporary frame wrap. This allows for both a stylish and protective product. The frame is made from transparent gray polycarbonate and has a soft rubber nose bridge and rubber tipped temples. RX-200 is available in five bifocal strengths. This new product incorporates bifocal segments into a molded dual curvature lens with integrated side shields. The RX-200 bifocal reading glasses also offer length and angle adjustable temples.
