TR90 glasses are crafted from a thermoplastic material known as TR-90, which stands for "Thermoplastic Rubber 90". This material is a lightweight, flexible, and durable plastic that's been specifically engineered to provide a comfortable and secure fit for eyewear. TR90 frames are known for their resilience and ability to retain their shape, making them an excellent choice for anyone who leads an active lifestyle or is looking for glasses that can withstand daily wear and tear.
The benefits of TR90 glasses are manifold. Firstly, they offer unrivaled comfort due to their exceptionally light weight, reducing pressure on the bridge of the nose and behind the ears. Secondly, they exhibit high flexibility, reducing the chances of breakage under stress or impact, which is perfect for sports and active use. Moreover, TR90 has a high resistance to sweat, oils, and UV light, ensuring that the frames last longer without losing their color or shape. Lastly, they are hypoallergenic, which is a critical feature for users with sensitive skin.
Both acetate and TR90 have their unique advantages. Acetate frames are known for their rich colors and lustrous finish, often considered more fashionable. They are made from a renewable resource, which appeals to environmentally conscious consumers. However, TR90 frames surpass acetate in terms of durability, flexibility, and weight. They are lighter and more comfortable for extended wear, which often makes them the preferred choice for active individuals or for those seeking comfort without compromising on style.
Comparing TR90 to Ultem (PEI - polyetherimide) is another matter of context and preference. Ultem is a high-performance polymer that boasts superior heat resistance, strength, and stability and usually caters to premium eyewear markets. TR90, on the other hand, prioritizes comfort and flexibility. If your primary concerns are lightweight design and comfort, TR90 may be better suited for you. However, if you're looking for glasses that can endure extreme conditions and temperature fluctuations, Ultem could be a superior choice.
While TR90 is lauded for its flexibility and lightness, polycarbonate is recognized for its high impact resistance and superb clarity. Polycarbonate lenses are often preferred where safety is a concern, such as sports eyewear or children's glasses, due to their shatter-resistant properties. On the frame side, TR90 offers more give and comfort than polycarbonate. Choosing between the two would depend on whether comfort (TR90) or impact resistance (polycarbonate) is more important for your eyewear needs.
