CR-39 polarized lenses for sunglasses
By careoptik August 2nd, 2023

CR-39 is a type of plastic material commonly used in the manufacturing of eyeglass lenses, including sunglasses.  Here are some key features and benefits of CR-39 polarized lenses for sunglasses:

  1. Lighter weight: CR-39 lenses are lightweight, making them comfortable to wear for extended periods. This feature is particularly appreciated by individuals who do not want heavy sunglasses weighing down on their noses and ears.

  2. Impact resistance: While CR-39 lenses are not as impact-resistant as polycarbonate lenses, they still offer decent resistance to small impacts and scratches. However, for high-impact activities or sports, consider lenses made from materials like polycarbonate or Trivex, which offer superior impact resistance.

  3. Optical clarity: CR-39 lenses provide excellent optical clarity and are less prone to optical distortion. This means you'll experience clear vision with minimal distortion while wearing CR-39 sunglasses.

  4. UV protection: CR-39 lenses can be coated with a UV-blocking layer, which helps protect your eyes from harmful ultraviolet (UV) rays. Polarized CR-39 lenses not only block UV rays but also reduce glare, enhancing visual comfort in bright outdoor conditions.

  5. Polarization: Polarized CR-39 lenses are particularly useful for reducing glare caused by reflections from surfaces like water, snow, and pavement. The polarization filter helps improve visual clarity and reduces eye strain in bright, sunny environments.

  6. Cost-effective: CR-39 lenses are generally more affordable compared to lenses made from other materials, such as polycarbonate or high-index materials. This makes them a popular choice for sunglasses, especially for those on a budget.

  7. Tint options: CR-39 lenses can be easily tinted to various colors, allowing you to customize your sunglasses according to your preferences and style.

Despite these advantages, it's worth noting that CR-39 lenses do have some limitations, such as lower impact resistance compared to certain other materials. If you have specific needs, such as higher impact resistance or thinner lenses, consider other lens materials like polycarbonate, Trivex, or high-index materials.

When purchasing sunglasses with CR-39 lenses, ensure they are from a reputable brand or retailer, and consider choosing a polarized version for better glare reduction and improved visual comfort in bright conditions.
