The Different Types of UV Protection Lenses

UV protection lenses are designed to provide a high level of protection against the harmful sunlight for your eyes. There are several types of sun lenses, each offering specific features in terms of protection and visual comfort.

UV400 Lenses

UV400 lenses filter all UVA and UVB light up to a wavelength of 400 nanometres. They offer complete protection against ultraviolet light, reducing the risk of eye damage in case of prolonged exposure.

Polarised Lenses

Polarised lenses eliminate disturbing reflections caused by sunlight reflecting off flat surfaces, such as water or snow. Highly sought after in mountain environments, and especially in early spring when the sun reflection is most intense on snow, they improve your vision and reduce glare, offering an optimal level of protection and visual comfort.

Photochromic Lenses

Photochromic lenses, on the other hand, automatically adapt to ambient light conditions, darkening in bright conditions and lightening in low light conditions. They are often chosen by athletes like cyclists or skiers, who often witness radical weather changes throughout the day. They allow you to carry only one pair of glasses, while being certain of being protected and seeing clearly in all conditions. Move from indoors to outdoors without noticing a difference, treat yourself to versatility.

Mirror Lenses

Coated with a thin reflective layer that reduces the amount of light reaching your eyes, Category 3 sunglasses with mirror lenses will be your allies for at the beach or in the mountains. Just like Julbo uses this technology on its Glacier glasses, these lenses provide additional protection against glare while adding a touch of style to your outfit.

Filter category 3 vs 4, Which Protection to Choose?

The UV (Ultraviolet) rating measures the intensity of the sun's ultraviolet light. A higher UV index indicates a more intense exposure to UV light. When it comes to choosing between a UV rating of 3 and 4, here's what you need to know:

Filter category 3:

• Suitable for moderate sunlight conditions.
• Provides basic protection against UV rays.
• Appropriate for normal sun exposure, for example, during occasional outings on partly cloudy days.
• Category 3 glasses can be used for driving.

Filter category 4:

• Suitable for intense sunlight conditions, as can be the case at the seaside or in the mountains.
• Provides superior protection against UV light.
• Recommended for prolonged sun exposure, especially in very sunny weather or at high altitudes.
• Category 4 glasses should not be worn for driving.

In general, the choice between filter categories 3 and 4 depends on the intensity of the sunlight you will be exposed to. If you plan to be under strong and direct sunlight for an extended period, opting for a UV rating of 4 may offer increased protection against the harmful effects of UV light. On the other hand, a UV rating of 3 may be sufficient for normal daily use in moderate sunlight conditions.
