Product Overview
Brand: Khirhf
Color: Black
Features:
- ✪ Deutan/Protan-Specific Contrast Amplifier: Khirhf color blind glasses enhance red-green contrast by 62% through patented multi-band filtration, aiding identification of traffic signals, wiring diagrams, and safety signage. Tool for improved differentiation – not full color restoration. Most users report noticeable improvement within 2-3 weeks, while optimal results typically require consistent daily use for neural adaptation.
- ✪ Precision-Assist TR90 Frame System: Military-grade TR90 frame withstands 20kg vertical pressure with non-slip silicone nose pads, designed specifically for Deutan/Protan users needing durable contrast aid in driving, warehouse work, and outdoor navigation. Blue light blocking resin lenses reduce screen strain while maintaining ISO-certified 87% hue differentiation accuracy.
- ✪ Scenario-Specific Contrast Optimization: These colorblind glasses sharpen red-green object edges in 12 high-frequency scenarios – emergency vehicle identification (200m+), ripe produce selection, and LED status lights monitoring. Includes Ishihara test references for monthly progress checks – 78% users report improved workplace efficiency within 6 weeks.
- ✪ Adaptive Aid for Active Lifestyles: Hydrophobic resin lenses maintain 92% clarity in rain/sweat conditions, paired with pressure-dispersing TR90 temples tested for 8,000+ head movements. FDA-registered as Class I medical device for Deutan/Protan assistance – ideal for gym sessions, cycling commutes, and equipment maintenance.
- ✪ Transparent Functional Scope: These colorblind glasses improve specific spectral contrasts through 12-layer nano-filtration, not color restoration. Includes Ishihara self-test guide with optometrist-approved interpretation manual. Ineffective for complete color blindness – consult specialists for optic nerve conditions.
Details: Description Khirhf Color Contrast Amplifier: Precision Engineered for Deutan/Protan Enhancement After 2,190 days of optometric research, Khirhf color blind glasses utilize 12-layer Nano-Filter Technology to enhance red-green contrast by 62% (measured per CIE 1931 standards). Engineered for electrical engineers, construction supervisors, and outdoor enthusiasts requiring precise safety signal detection. Military-Grade Construction TR90 Thermoplastic Frames: Survived 20kg crush tests (ASTM F1839-07) Blue Light Filter Lenses: 98% UV400 protection with ANSI Z80.3 compliance Adaptive Wavelength Targeting: 550-580nm optimization for traffic lights (610nm) & warning signs (520nm) 20Faster Wiring Diagnostics:87% improvement rate Emergency Vehicle ID Range:79% achieved 200m+ Color Sensitivity Gain:30% after 60 days (severe cases) Important Note: These glasses improve specific red-green contrast detection in individuals with functional cone cells. Not intended for complete color blindness or optic nerve disorders.23 Clinical Trial Results (412 Participants)
