Certification

Independent laboratory testing confirms that Post Seven CR-39 amber tint lenses block approximately 94–100% (inferred from spectral graph) of blue light (380–500 nm) while providing UV400 protection with extremely low UV transmission (UVB: 0.04%, UVA: 0.07%).

Our lenses comply with:

• ANSI Z80.3-2018 (United States) 🇺🇸
• EN ISO 12312-1:2022 (European Union) 🇪🇺
• AS/NZS 1067.1:2016+A1:2021 🇦🇺 🇳🇿

In simple terms, this means our lenses:

• Block harmful UV rays (UV400 protection)
• Significantly reduce blue light exposure in the evening
• Meet recognized safety requirements for optical performance
• Maintain proper signal light recognition for safe use

All testing was conducted by an accredited laboratory to ensure objective, third-party verification.

This certification confirms that Post Seven is not just tinted eyewear. It is tested circadian protection designed to support better sleep and recovery.
