Why Choose Category 1 Lenses?
Category 1 lenses feature a light tint, allowing more visible light to pass through. This makes them ideal for overcast days or situations where you need a clear view with some protection. These lenses are perfect for activities like driving, where you want to protect your eyes from UV rays but still need to see the road clearly.
Eye Safety and Comfort
Wearing the right pair of sunglasses is crucial for eye health. All Julbo glasses offer 100% UV protection (UVA, UVB, and UVC) and help shield your eyes from harmful UV and blue light. You can choose from different categories and lens tints to get the best combination of comfort, style, and safety for your needs.
Understanding Lens Categories
Sunglasses lenses are divided into five categories (0 to 4), based on the percentage of visible light transmission-the higher the category, the darker the lens. Category 1 is designed for low light or slightly sunny conditions, while higher categories are for brighter days. Remember, UV protection is independent of lens darkness: even clear or light-tinted lenses can block 100% of UV rays if they meet the right standards.
Choosing the Best Sunglasses
Whether you prefer polarised lenses for extra glare reduction or want a specific colour or frame to fit your style, there’s a pair for every activity and face shape. You can shop a wide range of sunglasses categories and learn more about UV protection and lens categories to make the right choice.
Everyday UV Protection
All Julbo sunglasses are designed to offer reliable UV protection and help protect your eyes from harmful UV rays and UVA and UVB exposure-every day, in every condition.

See clearly and stay safe with the right category of sunglasses-because your eyes deserve the best protection every day.
