Product Overview
Brand: Khirhf
Color: Black
Features:
- ✪ Experience Vibrant Color Clarity: 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. Mild users notice faster object recognition; severe cases require 2-3 months of 90min daily use for neural adaptation.
- ✪ Evidence-Based Contrast Aid: Clinically measured 0.41→0.59 CIE contrast ratio improvement for Deutan/Protan users. TR90 frame withstands warehouse/construction environments while blue light blocking resin lenses maintain ANSI Z80.3 optical standards. Daily 2-hour wear recommended for wiring diagnostics or safety sign recognition.
- ✪ Situational Recognition Accelerator: Sharpen red-green object detection in 8 critical scenarios: emergency vehicle tracking (150m+), ripe fruit selection, circuit board diagnostics. Includes Ishihara test references for monthly progress checks – 78% users report improved workplace efficiency within 6 weeks.
- ✪ Durable Contrast Enhancement System: Hydrophobic resin lenses repel 98% liquids without coating degradation, paired with pressure-dispersing TR90 temples tested for 500+ hours in humid environments. FDA-registered as non-prescription visual aid for Deutan/Protan-specific contrast challenges.
- ✪ Transparent Functional Scope: These colorblind glasses improve specific spectral contrasts through 12-layer nano-filtration, not color restoration. 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) 2023 Clinical Trial Results (412 Participants) Faster Wiring Diagnostics:87% improvement rate Emergency Vehicle ID Range:79% achieved 200m+ Color Sensitivity Gain:30% after 60 days (severe cases) Complete Support Package Ishihara Test Booklet Frame Adjustment Toolkit FDA 510(k) Exempt Certification 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.
