In a world where technology is an extension of ourselves, protecting our devices has become a priority. Glass lenses emerge as the silent guardians of our screens, but are they really the knight in shining armor we expect?

The brands that lead the market offer a promise of invulnerability. With names that evoke strength and durability, such as Gorilla Glass, Dragontrail and Dinorex, these lenses are not just accessories; They are an investment in peace of mind1.

But what are the advantages and disadvantages of this transparent shield? On the one hand, impact resistance is indisputable. A fall that previously meant the end is now just a scare thanks to the shock absorption of the tempered glass. In addition, its pristine transparency maintains the clarity of the screen, as if the protector were invisible.

However, all that glitters is not gold. Tempered glass can be more susceptible to peeling on devices with curved edges, and installation requires surgical precision to avoid bubbles or misalignment. Furthermore, although they resist impacts, they are not invulnerable to deep scratches that can be left by sharp objects.

And here comes the million-dollar question: How much does it cost to protect our precious devices? Prices vary, but generally, the lighter and thinner the crystals, the cheaper they will be. Tempered glass protectors can be found from affordable prices to more premium options, depending on the brand and quality

In conclusion, glass lenses are the modern ally in the battle against everyday accidents. They offer robust protection without sacrificing aesthetics or functionality. But like every hero, they have their weaknesses. The final decision lies with us, the users, who seek the perfect balance between security and practicality.

The Art of Forging Crystal Micas: A Journey from Casting to Unbreakable Protection

Glass lenses, those invisible guardians that protect our screens, have a fascinating manufacturing process. Let me take you behind the curtain to discover how these technology advocates are made:

Material Selection: The process begins with the choice of material. There are two main options: plastic (organic glass) and real glass (mineral glass). Both are the basis for glass micas.

Creating the Semi-Finished Lens: In this step, a semi-finished lens is produced. Professionals select the appropriate material based on the user's prescription and necessary measurements. This is where you decide if the lens will be custom or stock.

Freeform Technology: For individualized precision lenses, freeform technology is used. This advanced process, developed by ZEISS, creates almost entirely prescription lenses. The asymmetrical lens shape is precisely molded.

Stock Lenses: On the other hand, “off-the-shelf” stock lenses are manufactured through injection molding. These lenses are not customized and are produced in large quantities. They are suitable for standard vision corrections, but do not offer the same performance as precision lenses.

Essential Steps:

Locked: The glass block is fixed to a support that connects to the machinery.
Roughing and Precarving: The surface is rubbed with coarse grain abrasives to shape it.
Refined: The shape is perfected and the details are polished.
Polishing: The surface is meticulously polished.
Unlocked: The lens separates from the holder.
Cleaning: Impurities and residues are removed.
Surface Control: Quality is verified.
Cooling and Tempering: Finally, all the pieces are melted in an oven at 1500°C. The result is subjected to a cooling and tempering process, resulting in the resistant and transparent glass we know.

In short, glass lenses are more than just protectors; They are the result of a dance between technological precision and security. So, next time you look at your screen, remember the journey he took to protect you.

Are you ready to join the screen protection revolution?

Freeform technology is a revolutionary advancement in the manufacturing of optical lenses, especially progressive lenses. This technique has radically changed the production process, allowing unprecedented customization and millimeter precision. Here I explain more about how it works and its benefits:

1. Customization: Previously, laboratories acquired semi-finished bases with the progressive design already incorporated into the external part of the lens. Then, they worked on the inside to adjust the patient's prescription. With freeform technology, you start from a spherical base in simple view and both the patient's prescription and the design of the progressive are carved on the internal face¹.

2. Advantages:
    - Greater availability of base curves: This allows better adaptation to individual visual needs.
    -Wider fields of vision: Users enjoy clearer, broader vision, which is especially useful in progressive lenses.
    - Greater accuracy in design: Digital precision ensures that each lens fits perfectly to the user's visual requirements.
    - Design Customization: Each lens is manufactured with the user's unique specifications in mind, resulting in an optimized viewing experience.

3. Digital Manufacturing Process: Freeform technology uses digital design and finishing to create high-end, custom-made lenses. This includes parameters such as pantoscopic angle, vertex distance, facial angle and reading distance, ensuring that the lenses are completely personalized to the user.

4. Progressive Glasses: Progressive lenses are multifocal and allow you to see at various distances with the same lens. Freeform technology improves this type of lenses, offering a fluid transition between the different areas of vision and a faster and more comfortable adaptation for the user.

In short, freeform technology is a qualitative leap in lens manufacturing, providing a high-quality, personalized visual experience. It is a perfect example of how technological innovation can significantly improve our daily lives. 🌟
