Progressive No-Line 1.67 Super-Thin High Index Transitions® Lenses our Progressive No-Line 1.67 Super-Thin High Index Transitions® Lenses are manufactured using the same high quality 1.67 material as our single vision lenses, with ultraviolet filter and scratch resistant coating. Our Progressive lenses are of aspheric (flatter) design, incorporating a distortion free distance zone with a smooth intermediate transition to a wide reading area. Our 1.67 Super-Thin High Index Lenses, with a refractive index of 1.67, are substantially thinner and lighter than CR39 plastic and 1.67 lenses are the same as all other Opticians and Optometrists that may sell them as high index lens. They are manufactured with an aspheric (flatter) design as well as UV and scratch resistant coatings.

1.67 Super-Thin High Index Lenses are highly recommended for people who wear larger, rimless eyeglasses frames or who have smaller pupillary distances (i.e. less than 62mm).

1.67 Transitions® Lenses contain light-sensitive molecules that darken and lighten according to the intensity of ultraviolet light. Recent advances in Transitions® technology ensure that they perform consistently across a wide range of temperatures and climates.

The greater the intensity of the UV rays, the darker the lens becomes. The moment the UV rays are no longer present, the lens begins to fade back to almost clear. Transitions® Lenses do not change while driving in a car. All Transitions® lenses come with 100% UV protection.
