A Look at the Materials: What Makes Clip On Sunglasses Durable

Clip-on sunglasses are designed to be durable, capable of withstanding daily wear and tear, and providing long-lasting protection for your eyes. The durability of clip-on sunglasses is influenced by the materials used in their construction. Here’s a look at the materials that make clip-on sunglasses durable:

1. Lens Materials:

  • Polycarbonate: Polycarbonate lenses are lightweight and highly impact-resistant. They can withstand accidental drops or impacts without shattering, making them a popular choice for sports and active lifestyles.
  • Glass: Glass lenses, while providing excellent optical clarity, are heavier and more prone to shattering upon impact compared to polycarbonate. However, they are less susceptible to scratches.
  • TAC (Tri-Acetate Cellulose): TAC lenses are lightweight, shatter-resistant, and provide good optical quality. They are often used in high-quality clip-on sunglasses.

2. Frame Materials:

  • Metal: Metal frames, such as stainless steel, aluminum, or titanium, are known for their durability and resistance to corrosion. They are lightweight and provide a sleek, stylish look.
  • Nylon: Nylon frames are lightweight, flexible, and resistant to impact. They are a popular choice for sports-oriented clip-on sunglasses due to their durability.
  • TR-90: TR-90 is a thermoplastic material known for its exceptional durability and flexibility. Frames made from TR-90 are lightweight, comfortable, and highly resistant to impact.
  • Acetate: Acetate frames offer a classic, retro look and are durable when properly cared for. They are resistant to corrosion and can last for many years.

3. Hinges and Attachment Mechanisms:

  • Metal Hinges: High-quality metal hinges are durable and allow for smooth folding and unfolding of the clip-on sunglasses.
  • Spring-Loaded Clips: Spring-loaded clips in the attachment mechanism ensure a secure and snug fit onto your prescription eyeglasses. These clips are designed to withstand repeated use without losing their grip.

4. Coatings:

  • Scratch-Resistant Coatings: Many retro sunglasses come with scratch-resistant coatings on the lenses, which help protect them from minor abrasions and maintain optical clarity.
  • Anti-Reflective Coatings: Anti-reflective coatings on the back of the lenses can reduce glare from sunlight filtering through the trees or other light sources.

5. Rubberized Components:

  • Some clip-on sunglasses feature rubberized components, such as nose pads and temple tips. These provide additional grip and comfort, making them suitable for active outdoor activities.

6. Adjustable Features:

  • Clip-on sunglasses with adjustable nose pads and temple tips allow for a customized and secure fit, ensuring they stay in place during various activities.

7. UV Protection:

  • While not a material, it’s worth noting that clip-on sunglasses with built-in UV protection not only safeguard your eyes but also prevent the deterioration of the materials over time due to sun exposure.

In summary, the durability of clip-on sunglasses is achieved through a combination of materials, coatings, and construction methods. When choosing clip-on sunglasses, consider your lifestyle and activities to ensure that the materials used in their construction align with your needs for long-lasting eyewear that provides both style and functionality. Proper care and maintenance, such as cleaning the lenses and frames regularly, can also help extend the lifespan of your clip-on sunglasses.
