📊 Based on 2025 Ophthalmology Research
1. The Truth About Blue Light & UV Radiation
HEV Blue Light (415-455nm)
- Sources: Screens, LEDs, fluorescent lights
- Effects: Digital eye strain, sleep disruption
- Our Solution: CATRA-certified filtering lenses
UV420 Protection
- Blocks 100% of UVA/UVB + harmful violet light (400-420nm)
- Essential for: Outdoor workers, drivers, snow sports
- Our Standard: Exceeds ANSI Z80.3 requirements
2. Who Needs Combined Protection?
Digital Professionals
4+ hours screen time? Our NOORBlue lenses reduce eye strain by 27% (2024 study)
Outdoor Workers
UV420 shields from sun + reflected glare (concrete, water, snow)
Blue Light & UV420: Myth vs. Science
MYTH
“All blue light is harmful”
Many believe all blue wavelengths damage eyes equally.
FACT
Only 415-455nm is high-energy
Our lenses selectively filter harmful wavelengths while allowing beneficial blue-turquoise light (465-495nm) that regulates circadian rhythm.
MYTH
“UV protection is only for sunglasses”
40% of UV exposure occurs when not in direct sunlight.
FACT
UV420 should be in all eyewear
Our clear lenses block 100% UV up to 420nm, protecting against:
- Reflected UV from surfaces
- Office fluorescent lighting
- High-altitude exposure
MYTH
“Yellow tint = better protection”
Many assume darker tints mean more protection.
FACT
Tint ≠ protection level
Our NOORBlue technology provides:
| Lens Type | Blue Light Filtered | UV420 Protection |
|---|---|---|
| Clear | 92% | 100% |
| Yellow-Tinted | 95% | 100% |
“In my practice, I recommend UV420 protection year-round, not just for sunglasses. The violet gap (400-420nm) contributes significantly to retinal aging.”
3. Our Clinically Tested Solutions
NOORBlue
- Blocks 92% harmful blue light
- UV420 protection
- Anti-reflective coating
Why UV420 Matters More Than Standard UV400
Standard UV400 blocks to 400nm. Our UV420 protection covers the dangerous “violet gap” (400-420nm) linked to retinal damage.
