What lens material will my Rx glasses be made from?Updated 2 months ago
Lens material is automatically assigned based on your prescription power. Standard-range prescriptions (sphere +1.50 to −4.25D) receive polycarbonate lenses — impact-resistant and lightweight. Higher-power prescriptions (sphere +1.75 to +3.00D or −4.50 to −8.00D) receive 1.67 High Index lenses, which are thinner and lighter for stronger Rx values. You do not select the lens index — it is determined automatically at order processing.
