How to choose the right sunglasses for the mountains and the ocean?

Why is choosing the right sunglasses essential?

Whether in the mountains or at the ocean, your eyes are subjected to intense exposure to UV rays and glare. Choosing the right sunglasses is essential to protect your vision and fully enjoy your activities (surfing, skiing, hiking, sailing, etc.).

UV protection: the number 1 priority

• 100% UVA/UVB protection is mandatory for all pairs of glasses.
• In the mountains, UV intensity increases by 10% per 1,000 m of altitude .

• At the ocean, water and sand reflect up to 25% of UV rays .

👉 Always look for the mention UV400 or 100% UV .

Polarized lenses: an essential accessory in the mountains and on the ocean

Polarized lenses filter out glare and significantly improve visual comfort, which can prevent headaches after long days of exposure:

• Surfing, sailing, fishing : better visibility on the water.

• Skiing, snowboarding, mountaineering : sharper terrain and enhanced safety.

At 2NDLIFE , our VisionHD™ lenses are all polarized, made in France from recycled pine resin (ISCC Plus) : performance and respect for the environment.

Categories of sunglasses lenses: which intensity should you choose?

Sunglasses are classified from category 0 to 4 according to their level of filtration:

• Category 3 : ideal for the ocean, beach and summer activities.

• Category 4 : perfect for high mountains or glaciers (prohibited for driving) .

👉 For versatile use at sea/in the mountains, opt for category 3 .

What color lenses are best for the mountains and the ocean?

• Neutral grey : natural vision, perfect for everyday use.
• Brown/gold : enhanced contrast, ideal for the mountains.
• Blue/silver mirror : maximum glare reduction, perfect for the ocean.

👉 Our 2NDLIFE models are available in several shades to suit every practice.

Comfort and durability: two criteria not to be overlooked

Outdoors, your glasses need to be sturdy, lightweight, and resistant to the elements (salt water, sand, wind). Nothing is more annoying than glasses that break on the first outing or that press too hard on your nose.

👉 Our lenses have the same technical characteristics as traditional polycarbonate: lightness and resistance, which guarantees you unparalleled comfort and longevity.
