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.

Helped me ace my final!
Format: Paperback
I strongly recommend this study guide to anyone who needs to understand and apply the pathophysiology in a final exam. The original book was the textbook for my pathophysiology course- it is over 1000 pages and overwhelming. This study guide broke down the important aspects of each chapter into very doable practice questions. The answer guide at the back has perforations - so I tore mine out and it made it so much easier to follow along and study with this guide. If you are struggling to learn/memorize/understand/apply all the pathophysiology concepts-I strongly suggest using this study guide. It really helped me get through my exam - and I am not a good test taker. Good luck in your studies!

Helpful for exam preparation
Format: Paperback
This is helpful in getting me ready for exams. I fill it in and then study it with my other notes and resources before exams. The activities can be fun (crossword puzzle) or simple fill in the blank. I think I have found 1 or 2 errors that do not match up to the reading but I find errors in the online questions provided with the textbook as well. Helpful to absorb detailed topics. I appreciate that there are answers in the back also so I can ensure I have found the right answer. Love the section that provides hypothetical patient or family questions where I can take the knowledge and put it in layman's terms so I'm ready to explain the pathophysiology in basic terms when needed.

Important to Know
Format: Paperback
I very much like this study guide. It has helped me study for my exams. Some of my test questions have even come straight from this book. HOWEVER, I do caution anyone who buys this book to double check the answers. I have come across MULTIPLE typos and incorrect answers in the Answer Key. I like the content of this book, but for a professionally printed book, the overall completeness is poor.

Great purchase
Format: Paperback
This was a great addition to the textbook. The textbook was awful in my opinion but this study guide really explained it in a easy to understand and direct way. I love the matching, fill in the blank and most importantly the case studies. Really helps you figure out what you may encounter pathophysiology wise when caring for patients.
