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.

My children occasionally need a really good nights rest.
Sometimes my kids need a good night's rest and this is my go-to product for that! The raspberry flavor makes it easy for them to take as well.

Didn't Notice Difference
The taste is actually pretty good, honestly it's more like a treat than a supplement... but I haven't noticed any significant changes after going through the entire bottle. They didn't cause any upset stomach or side effects, which is a plus, but the overall benefits feel negligible.

GREAT CONCEPT AND DESIGN
I bought these Feminine Balance Gummies because I was intrigued by the approach that was utilized. For me, I have been involved with lactobacillus formulas and probiotics with incorporating yogurt (the really healthy kind not the ones with a lot of advertising) to deal with yeast overgrowth. Typically I am experiencing a problem because I am consuming too much sugary foods (causing the body's resources to be depleted) or because I have taken a course of antibotics which killed both the good and bad bacteria in the body and now needs replenished. So, my first impression was the intrigued by the use of Pineapple as a part of the formulation, which is unusual but a good choice nonetheless because it is very beneficial for digestion and also for pain reduction. I liked the taste of the gummy, it tasted like Pineapple candy. The inclusion of Vitamin C seemed a bit of a stretch and is included to enhance the immune function. There are lactobacillus strains but the manufacturer has kept the strains used as a proprietary secret - which I find a bit frustrating as a consumer. Whatever it is, there is a billion of them (is this per gummie?). The manufacturer does support the use of vegan only products, it is also "clean" Halal, it is gluten free and allergen free. So, it appears they have carefully considered the inclusion of each ingredient for benefit. So here is the real test, yes, I have had the desired outcome by improving my "lady garden" and this is a very viable product in my opinion. I would recommend it to others.
