Progressive Transitions® XTRActive® CR-39 Lenses

Keep your compatible frames and upgrade to Progressive Transitions® XTRActive® CR-39 Lenses. CR-39 plastic offers an economical option for eligible lower prescriptions. Progressive lenses combine distance, intermediate, and reading correction in one lens without a visible bifocal line. XTRActive® New Generation technology provides extra darkness outdoors, activates behind the windshield, and retains a slight protective tint indoors. Choose Gray, Brown, or Graphite Green where available. Upload your prescription during ordering or send it later before production. RenewLens installs your replacement lenses in your compatible frames, with free prepaid shipping both ways.
