When discussing luxury sunglasses, most of the focus is usually on the design and durability of the outer frame. However, from a medical and practical standpoint, the lens is the first line of defense for your eyes, directly responsible for the quality of your vision and your comfort while driving or in bright sunlight.
At Solaris eyewear, we utilize polarized TAC (Triacetate Cellulose) lenses across a wide range of our models. In this article, we'll explain the technical and structural aspects of these lenses, their practical advantages, and why they were specifically chosen.
1. What is TAC technology and how does it work?
TAC lenses are not just a colored plastic layer, but rather an integrated engineered lens consisting of 7 to 9 layers that are processed and pressed together using advanced technologies:
- The central layer (core): This is the polarizing filter (Polarizing Core), which is the layer responsible for blocking the reflected horizontal light rays that cause deep glare.
- Surrounding layers: This layer is surrounded on both sides by ultraviolet (UV) filtering layers, followed by hard outer layers that are resistant to scratches and light impacts to ensure the lens's durability.
2. The true advantages of TAC lenses in our summer weather
The selection of this material for Solaris customers is based on tangible, real-world performance:
- High Polarization: These lenses eliminate up to 99% of glare. This means the disappearance of annoying reflections from other car windows, asphalt, or shiny surfaces, providing very comfortable vision during daytime driving and long journeys.
- Complete UV400 protection: The lenses effectively block 100% of harmful light waves (UVA, UVB and UVC), protecting the retina from strain and photoburn caused by prolonged sun exposure.
- Visual clarity and color purity: The lens gives you a view of its natural and realistic colors without any distortion of dimensions or visual aberration (Distortion), which is the main reason that it prevents headaches and eye strain while wearing it for continuous hours.
3. Geometric balance: Why TAC and not glass?
Traditional glass lenses offer excellent clarity, but they suffer from two fatal flaws: extreme weight and susceptibility to breakage and fragmentation inside the eye upon impact.
Since Solariz frames are made from a luxurious, weightless acetate material, the clever engineering decision was to combine them with ultra-lightweight TAC lenses. This combination ensures you get glasses that are both sturdy and luxurious as frames, while remaining light and comfortable on the bridge of your nose and ears without leaving any irritating marks.
4. Candor and realism: What are the limits of this material?
Based on the principle of absolute transparency with our clients, these are the technical points to consider when purchasing TAC lenses:
- Not for violent sports: Despite its flexibility and resistance to everyday impacts, it is not intended for violent or physically contact sports (such as basketball or mountain biking), as these sports require thick polycarbonate lenses that are resistant to direct breakage.
- Sensitivity to excessive heat: Because the lenses are made of integrated layers, leaving the glasses inside a car's dashboard under direct, intense sunlight for several days may affect the integrity of these layers in the long run. Luxury glasses belong in your eyes or their case.
In conclusion
The combination of a durable vegan acetate frame and TAC polarized lenses in Solarize sunglasses offers the perfect balance of a pair of glasses that will last a lifetime: luxurious and substantial outer construction, combined with exceptional lightness, visual comfort, and medical-grade safety for your eyes. They're more than just an accessory; they're an investment in your vision and everyday style.
