Let's be real – when you slip on a new pair of sunglasses, the first thing you're thinking about is how good they look (and you should!). That confidence boost is everything.
But have you ever stopped to think about what your sunglasses are made of?
At By Charley, we’re obsessed with what happens behind the scenes. We believe that truly great style isn’t just about appearance; it’s about intention. It’s about feeling as good about what you’re wearing as you look wearing it.

So, let’s pull back the curtain and dive into the heart of our frames: the materials.
1. The Dynamic Duo: Plant-Based Acetate & Metal
This combination is a classic for a reason, and we’ve made it even better.
-
What It Is: Imagine the rich, unique look of classic acetate, but made from renewable resources like wood pulp and cotton. Now, pair that with sleek, durable metal accents, often in the temples or as a subtle inlay. It’s the best of both worlds.
-
Why It’s a Winner:
-
Style That Pops: You get the depth, color, and individuality of plant-based acetate with the sharp, refined detail that only metal can provide. It’s a sophisticated, high-fashion look.
-
Tailored Fit: The magic here is adjustability. The metal core in the temples can often be gently adjusted by an optician to fit the unique contours of your face perfectly. It’s custom comfort, just for you.
-
Built to Last: This combo is a workhorse. The strength of the metal complements the substance of the acetate, creating a frame that’s resilient and made to be a long-term companion.
-
-
The By Charley Touch: Our acetate is plant-based, reducing our reliance on fossil fuels. It’s a small but mighty step towards a more conscious wardrobe.
2. The Featheweight Powerhouse: TR90
You might not know the name, but you’ll definitely love the feel.
-
What It Is: TR90 is a super-flexible, ultra-lightweight thermoplastic polymer. Think of it as a high-tech nylon that’s been engineered specifically for wearability. It’s so light you might forget you’re wearing it!
-
Why It’s a Winner:
-
All-Day Comfort: This is, hands down, one of the most comfortable materials out there. It’s perfect for travel, sports, or just those days when you don’t want anything weighing you down.
-
Memory & Flexibility: TR90 has fantastic "shape memory," meaning it can bend and twist and then spring right back to its original form. No more worrying about your frames getting warped in your bag or from an accidental sit-on.
-
Hypoallergenic Hero: It’s a great choice for those with sensitive skin, as it’s non-toxic and contains no common allergens like nickel or BPA.
-
-
The By Charley Touch: We source high-quality TR90 for its unbeatable blend of comfort and durability, making it the go-to for an active, on-the-go lifestyle.
3. The Durable & Conscious Choice: High-Quality Recycled PC
PC (Polycarbonate) is famous for its toughness, and we’ve given it a sustainable upgrade.
-
What It Is: Polycarbonate is an impact-resistant material known for its strength. Our version uses high-quality recycled PC, giving a second life to existing materials without compromising on performance.
-
Why It’s a Winner:
-
Nearly Unbreakable: If you’re rough on your shades or need a pair that can keep up with kids and adventure, this is your material. It’s incredibly impact-resistant.
-
Lighter on the Planet: By choosing recycled PC, we directly reduce plastic waste. It’s a simple equation: great product + less environmental impact = a win-win.
-
Cost-Effective Quality: This material allows us to offer exceptional durability and a lower price point, making sustainable, high-performance sunglasses accessible to more people.
-
The Bottom Line: It’s All About Choice.
At By Charley, we don’t believe in a one-size-fits-all approach. Your life is unique, and your sunglasses should be, too.
