Sunglasses lenses come in a variety of materials, each with its unique characteristics and suitable applications. Here are some common sunglass lens materials:
Polarized lenses: These are special optical films that allow light to pass through only in a specific direction, effectively reducing UV damage to the eyes and improving visual clarity.
Polycarbonate lenses (PC lenses): Primarily made of polycarbonate, these lenses are strong, durable, impact-resistant, and lightweight. Their UV protection is long-lasting and stable, making them suitable for sports.
Nylon lenses: Made of transparent polyamide, these lenses offer high elasticity, excellent optical quality, and impact resistance. They are commonly used as protective gear and are suitable for athletes and professional protective gear users.
Photochromic lenses: These lenses contain UV absorbers and photochromic dyes that absorb and block UV rays, changing color under UV exposure to adapt to different lighting conditions.
Resin lenses: Made of resin, these lenses are lightweight, heat-resistant, and impact-resistant. They effectively block UV rays, meeting everyday wear needs.
Glass lenses: Stable optical performance, not easily deformed, and offer high clarity.
TAC lenses: Cellulose triacetate film, with good light transmittance but poor abrasion resistance and unstable optical properties.
AC lenses (acrylic lenses): Strong, lightweight, with extremely high transmittance and excellent anti-fog properties.
