LOCKHART

Why we made it.

Lockhart is the perfect blend of form and function. With a sculpted square shape and bold lines it suggests that it is all style—but actually, it's all substance. Behind it's causal exterior, is an expertly engineered tool that weighs half the weight of similar styles from other brands. A wolf in sheep's clothing, it is a modern reimagining of a classic silhouette infused with our performance DNA.

CORE TECHNOLOGY

“The fit is exponentially better than so called premium glasses. Someone would have a difficult time to go with another company when I need a new pair. I'm a ROKA convert!”

- Eric L.

LENS MATERIALS

Standard

POLYCARBONATE

The highest quality PC, featuring anti-reflective, anti-scratch, super-hydrophobic, oleophobic and fog resistant coatings. Lightweight, impact resistant, 100% UV protection.

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.

“The spring hinges are great. Super lightweight. They are so stylish but also perfect for workouts and runs. They won't slip even with sweating which is the reason I gave ROKA a try in the first place.”

- Devon C.

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.
