Glass technology

In the production of glass in sunglasses are used in a variety of cutting-edge technologies. These glasses must be solid and secure, it must also bring comfort for the eyes, so the impact may not shatter, thay may not glistern and should comfortably dampen direct light. We are think about these important facts, while we produce lenses for ours sunglasses If you are interested in how to achieve the above-mentioned properties, check the text below.

Glass contruction

 We use the best lens materials in the world – Techlite Glass for optical precision and Carbonic for impact resistance. We precisely alight the finestpolarized filters and finish our lenses with multi-layer mirror, Anti-Reflective, anti-scratch, and Hydroleophobic lens coatings. The end result is an artfully crafted lens that preserves color perception and delivers optimized optical clarity and precision in all environments.


What you should know about the glasses

ChromaPop – polarized glasses

ChromaPop lenses employ a unique combination of patented polarization, and color management technologies. The result is a lens that delivers exceptional clarity, high contrast, and dynamic color optimization.

Techlite – polarized glasses

These polarized glasses make visual environment, which is ideal fot activites in water. 20% lighter and up to 12 times more scratch-resistant than regular glasses.


Carbonic lenses are optically tuned in a wide range of tints offering you visual comfort and protection from the urban grind to the mountaintop.

NXT photochromic technology

NXT photochromic glasses are modify tone filter UV light thameselves.

Exceptional clarity and sharpness will guide you through the day.

Light transmittance

There are 5 levels of normalized sun filter categories, marked 0 – 4. . The number reflects light transmission – higher filtr category means lower light transmittance by lens and it is darker. All of ours glasses has filtr level 3.

0 Non-color or verry light filter – light transmittance 80-100%
1 Light filter – light transmittance 43 – 80%
2 Medium dark filter – light transmittance 18 – 43%
3 Dark filter – light transmittance 8 – 18%
4 Verry dark filetr – light transmittance 3 – 8%, suitable to the sea and the mountains, on the contrary, unsuitable fot driving.


 Scientifically advanced material lenses.

ChromaPop lenses employ a unique combination of patented polarization, and color management technologies. The result is a lens that delivers exceptional clarity, high contrast, and dynamic color optimization.

This advanced material can accept the sophisticated dyes and tints needed to create our proprietary visual experience. Meaning ChromaPop delivers high contrast, select color filtering and color enhancement better than other lens materials commonly used in sunglass and prescription sunglass lenses. Known throughout the industry for ophthalmic grade optics and superior performance,Trivex® is the material that powers the ChromaPop lenses.

This gives ChromaPop lenses a visual acuity approaching glass,with benefits that surpass other materials.

Polarized lenses with photochromic technology to adapt to ever – changing light conditions.

With Smith Polarchromic, we combine the glare-free benefits of advanced polarization with UV sensitive, self-tint-adjusting photochromic technology to bring you the most advanced sunglass lenses we have ever created. How do we do it? Precise amounts of silver halide crystals are infused into the glass lens material during their creation. These microscopic crystals automatically change orientation in response to UV light which results in a shift in tint either increasing or decreasing Visible Light Transmission (VLT), fine tuning the tint of your lens in response to ambient light conditions as they change throughout the day. The result? You get a lens which offers crisp optics and soothing light levels at all hours, allowing you to focus on what matters most from dawn to dusk.


Precision polarization engineered to obliterate glare.

It’s like noise-canceling headphones for your eyes. Glare off of horizontal surfaces like snow, water, and asphalt, decreases depth perception, and reduces visual acuity which causes eye fatigue. We precisely align the polarized visual layer inside our lenses to filter out 99.9% of this “visual static” for a finely tuned view of the action.



„Objects in lens are exactly the same as they appear.” When light passes through a medium it refracts, i.e. changes course. If left uncorrected, this refraction can cause visual distortion and eye fatigue

Smith’s Tapered Lens Technology (TLT) straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with 100% accuracy and maximum comfort.

Hydroleophobic coating

Highly scratch resistant, hydrophobic (water repellent), super slippery, debris resistant and anti-static.

Anti-reflective coating

Vacuum applied Anti-Reflective (A/R) coatings on the back side of the lens will eliminate bothersome sidelight reflections.


Frame construction

The shape of frame and body is verry important for your feeling. One thing is shape, which is designed on the base of ergonomical measuring, and second thing is raw material. Sunglasses have to be flexible enough for good fit you, and also strong, to not break during handling. All informations about raw materials, producting of frames, megols and hinge and also about evolve, you can find in the text bellow.

Base curve

The base curve is the radius of the sphere measured from the back of the lens. Laceto features styles with 6,8, and 9 base lens curvature. Models that
include 6 base tend to be more flat relative to your face. While 9 base styles provide the maximum amount of wrap around your face.

Spring hinge

Stainless steel optical hinges incorporate small springs within the hinge structure that keep the temples snug against your head. This type of hinge is designed to smoothly self adjust in order to accommodate a broader range of head shapes and sizes more comfortably..


Placed at the nose and on the temple tips, Megol gently grips your skin to help keep the frame in place. The gripping power increases when introduced to moisture.

Handmade acetate

A 33-step handcrafted process that features the inclusion of wire-core temples for a customized fit. A huge variety of rich color combinations that possess depth and have a distinct character are made possible with this material.


Ultra lightweight with an immaculate fit. Classic silhouettes constructed with premium stainless steel or sculpted alloy metal frames. Adjustable silicone or optical nose pads provide all day comfort.

Grilamid® TR90

Resilient, tough, and flexible. Grilamid® TR90 is an exceedingly light and durable plastic that will maintain its shape under all temperature conditions.


We incorporate the revolutionary, Rilsan® Clear material into what has become the largest eco-friendly sunglass collection in the world. This material allows us to create lightweight, durable frames, that are over 53% bio-based.

Rilsan® Clear is derived from the renewable, non-genetically modified castor plant. Characteristics of this material include flexibility, lightweight, high elasticity, remarkable toughness,and excellent chemical resistance. Most importantly, this material is not petroleum based.

Why is 53% bio-based important? Through extensive testing and field trials, Smith has found the correct balance of materials required to sustain performance and durability, while reducing our environmental impact.
