PREMIUM COATINGS

All Island Optics eyewear has the following lens coatings.

Scratch Resistance: Highly abrasion-resistant coating which increases surface hardness allowing lenses to exceed testing requirements.

Hydrophobic & Oleophobic: Helps repel water and reduce oil buildup.

Anti-Reflective: Reduces glare and unwanted reflections

Marine: Marine coating which protects lenses from saltwater use.

LENS MATERIAL

Lens material options for our prescription frames 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.

Single Vision Most common prescription that corrects for one field of vision (far distance, intermediate, or near vision correction).
