Single Vision Transitions® XTRActive® CR-39 Lenses

Keep your favorite compatible frames and upgrade to Transitions® XTRActive® New Generation single vision lenses in CR-39 plastic. This economical material is a practical option for lower prescriptions and everyday distance or reading use. XTRActive lenses become extra dark outdoors, activate behind the windshield, and retain a slight protective tint indoors. Choose Gray, Brown, or Graphite Green. Single vision lenses provide one prescribed viewing range. 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.
