Both materials reference the thickness of the lens.
High Index 1.60 lenses are thinner & lighter than CR-39, polycarbonate or glass. Recommended sphere range is -/+ 4.00 through -/+ 6.00.
High Index 1.67 lenses are thinner than High Index 1.60, polycarbonate, CR-39 or glass. Recommended sphere range over -/+ 6.00.
Ultra High Index 1.74 is the thinnest & lightest plastic material. AR coating is included, recommended sphere range is 0.00 through -/+ 18.00
There are so many variables, a lot of this depends on frame style, size and your prescription. Each lens materials has the same properties as polycarbonate so anti-scratch is included and they block UV rays. AR (non-glare) coating would need to be ordered extra for most lenses except 1.74.

You are correct. Ultra High Index comes with AR coating, anti-scratch and UV coating by default.
Let me know if we can help you further.
Can you please confirm that if I were to order Ray Ban RX8633 frames with prescription High Index 1.74 lenses, the lenses will include AR, UV protection and anti-scratch coatings without the need to pay extra for them? This is not clear in the ordering process and I saw your earlier post from April but wanted to know if it still applied today.
Thanks for the post. Ultra High Index comes with AR coating, anti-scratch and UV coating by default. The lenses of the 1.74 must be clear and cannot be tinted.
I hope this helps. Call me when you are ready to place an order at 1-800-504-5897 ext 320. I will help you personally!
