Lenses Technology:

✓ CR-39 Custom-Made Lenses

CR-39 is made by polymerization of diethyleneglycol bis allylcarbonate (ADC) in presence of diisopropyl peroxydicarbonate (IPP) initiator.
"CR-39" is an abbreviation of Columbia Resin 39. CR-39 has the highest Abbe value of any lens. An Abbe value defines the chromatic aberration of material, and this effect is generally more noticeable in peripheral vision than when looking through the center of a lens. Resin raw is injected into lenses mould. After that, the anti-scratch coating is applied.

• Anti-scratch technology.
• Unique colors, with over 4+ tests to achieve the final result.
• Gradient colors with smooth transition.
• All DE products have V-Groove (Removable Lenses - Technical feature that allows lenses to be removable, in order to add prescription etc)

+ Metal Parts.

Metal Core wire with IP plating that prevents oxidation and wear.

✓ 100% UV Protection.
The lenses we use, have a UV protective coating with maximum filtration against harmful sun rays.

✓ Lenses Category: 3.

The bigger the category number of lenses, the better. Category 3 in lenses, is considered better than categories 2 & 1. This is because they provide extra protection from both visible and UV light. These lenses allow less than 20% of visible light to penetrate the lens. This means that they will block out 80%+ of light. Category 3 lenses are considered some of the best lenses in the optical industry.

Acetate Technology:

✓ Italian (Mazzucchelli) Acetate.
Our Acetate Materials are coming from some of the biggest acetate factories in Europe. Fabricated from wood pulp and cotton.

Mazzucchelli 1849, is an Italian Company based in Castiglione Olona, and is a worldwide leader in the manufacturing and distribution of sheets made of Cellulose Acetate, polymer of natural origin, traditionally used in the production of optical and sunglass frames. Cellulose acetate is a modified natural polymer. To obtain Cellulose Acetate Mazzucchelli starts with the selection of renewable sources such as certain varieties of trees and cotton linters. From these sources the purest part of the cellulose is extracted which is subsequently treated with Acetic Anhydride and transformed into Cellulose Acetate powder.

✓ Engraved DE logo on the temples.
Every pair has the engraved logo, product name, and measurements on both temples.

Comes with a luxury box, eco-leather case, and cleaning cloth.
