When shopping for sunglasses, you may notice terms like Category 1, Category 2, Category 3, polarized and UV400. While these all relate to sunglass lenses, they don't mean the same thing.

Understanding the difference can help you choose the right Le Specs sunglasses for your lifestyle, whether you're looking for a lighter fashion tint, everyday sunglasses or darker lenses for bright conditions.

What Do Sunglasses Lens Categories Mean?

Sunglass lens categories describe how much visible light passes through a lens and how effectively it reduces sun glare.

Le Specs offers sunglasses in three lens categories: Category 1, Category 2 and Category 3. You can find the lens category for each Le Specs style under UV Protection in the Product Details dropdown on its product page.

Category 1: Light Tint Sunglasses

Category 1 lenses offer limited protection against sun glare and are typically lighter in appearance.

They're suited to lower-glare conditions and customers who prefer a subtle, fashion-focused tint.

Under the applicable filter category descriptions, Category 1 provides moderate UV protection.

Category 2: General Purpose Sunglasses

Category 2 lenses offer good protection against sun glare, making them a versatile choice for everyday outdoor wear.

They're suited to moderate sunlight and provide a balance between visible light transmission and glare reduction.

Category 2 is described as providing good UV protection under the relevant sunglass filter standard.

Category 3: High Sun Glare Protection

Category 3 lenses offer high protection against sun glare and are designed for bright, sunny conditions.

They allow less visible light through than Category 1 or Category 2 lenses, making them a suitable choice when stronger sun glare reduction is needed.

Category 3 is also described as providing good UV protection under the relevant standard.

It's important to remember that a Category 3 rating does not automatically mean a lens is UV400.

What's The Difference Between UV Protection And Lens Category?

UV protection and lens category measure different characteristics of sunglasses.

Lens category refers to visible light transmission and sun glare reduction.

UV protection refers to how effectively the lenses filter ultraviolet radiation.

You may also come across the term UV400, which refers to UV protection through wavelengths up to 400 nanometers.

A darker lens does not automatically provide better UV protection, and a Category 3 classification alone does not establish UV400 performance.

What Are Category 2 And Category 3 Polarized Sunglasses?

Le Specs also offers polarized sunglasses in Category 2 and Category 3.

Polarized lenses are designed to reduce reflected glare from surfaces such as roads and water.

Category 2 Polarized: Combines good sun glare reduction with additional reflected glare reduction.

Category 3 Polarized: Combines high sun glare reduction with additional reflected glare reduction.

Polarization is a separate feature from lens category and UV protection. A polarized lens is not automatically UV400 simply because it is polarized.
