ZILKER
Why we made it.
CORE TECHNOLOGY
“Honestly, I never thought I would spend more than the $15 gas station sunglasses. But I figured I would try these and see if they lived up to the hype. We do a lot of outdoor activities. These are the real deal. No slippage, perfect for biking, hiking, all outdoor stuff. I liked them so much I bought a second pair. Very happy with them and recommend to everyone I know.”
LENS MATERIALS
POLYCARBONATE
The highest quality PC, featuring anti-reflective, anti-scratch, super-hydrophobic, oleophobic and anti-fog coatings. Lightweight, impact resistant, 100% UV protection.
Trivex
Features all of the benefits of our polycarbonate lenses but even lighter and more optically clear, both centrally and peripherally.
High Index
Thinner and lighter to accommodate strong prescriptions.
LENS TINTS
CLEAR
Premium optical lenses with outstanding clarity.
PHOTOCHROMIC
The tint of the lens adjusts in different light conditions. Lighter inside, darker outside.
BLUE LIGHT BLOCKING
A coating is applied to filter out blue light. Helpful for those who spend a significant portion of their time in front of screens.
“My previous iterations of eyeglasses tended to either fall off or swing from my ears when facing down. The grips on my ROKA Zilker pair keep everything in place, even with decent movement, and they are lightweight for their chunky frame.”

LENSES
PREMIUM COATINGS
All ROKA performance eyewear has the following lens coatings.
Scratch resistance Highly abrasion-resistant coating which increases surface hardness allowing lenses to exceed testing requirements.
Fog resistant Reduce fog and water formation on the lenses. Smooth coating surfaces allow for easy cleaning after use.
Hydrophobic/Oleophobic Help repel water and reduce oil buildup.
Anti-Reflective Reduce glare and unwanted reflections
OPTIONAL COATING
Blue light blocking An optional lens coating that reduces the amount of high energy visible (HEV) blue light from heavy screen-time use that extends late in the day and into the night.
LENS MATERIAL
Lens material options for this frame are below.
Polycarbonate Thinner than mineral glass by up to 25%, lightweight with increased impact resistance.
Trivex Best optical clarity (centrally and peripherally), ultra lightweight, increased impact resistance and resistant to chemical and stress.
High Index Ideal for stronger power prescriptions that allow for thinner lenses, increased scratch resistance, lower impact resistance as compared to polycarbonate or Trivex. High Index lenses are recommended for prescription powers above +/- 4.00 Sphere and/or Cylinder above +/- 2.00.
OPTICAL TYPE
Prescription and non-prescription options for this frame are below.
Single Vision Most common prescription that corrects for one field of vision (far distance, intermediate, or near vision correction).
Progressive Multifocal lenses for far distance, intermediate, and near vision. Progressive lenses have added magnification at the bottom of the lenses for up close reading.
Readers Non-prescription lenses that have magnification (+ power). Designed to enhance up close reading and do not require a prescription to purchase. Power range offered- +0.50 to +3.00 (in +0.50 diopter increments).
