Spocwd Color Blind Glasses for Men, Color Vision Deficiency Correcting & Enhancing Glasses for Red Green Colour Blindness | Indoor/Outdoor Use, TR90 Frame — Open-Box, 5% Off

✪ Deutan/Protan-Specific Contrast Adjustment​: Qlonn color blind glasses use multi-band filtration to modify red-green contrast, helping users differentiate traffic signals, wiring diagrams, and safety signs. This tool supports improved distinction — it does not restore normal color vision. ✪ TR90 Frame with Non-Slip Fit​: The TR90 frame includes silicone nose pads for secure positioning. Blue light blocking resin lenses may reduce visual fatigue during screen use. Designed to provide contrast support in settings such as driving, warehousing, and outdoor navigation. ✪ Contrast Support in Common Situations​: These glasses assist in distinguishing red-green edges across everyday tasks — spotting emergency vehicles, selecting ripe produce, or reading LED indicator lights. An Ishihara test card is included for periodic self-checking. ✪ Lenses and Frame for Active Use​: Water-repellent resin lenses help maintain visibility in rain or sweat. The TR90 temples are built for repeated movement, making the glasses suitable for gym workouts, cycling, or equipment maintenance. ✪ What These Glasses Do — and Don’t Do​: They filter specific wavelengths to alter color contrast, not to restore full color perception. A self-test guide with interpretation instructions is provided. Not effective for total color blindness; individuals with optic nerve conditions should consult an eye care professional.

Spocwd Color Contrast Amplifier: Precision Engineered for Deutan/Protan Enhancement

After 2,190 days of optometric research, Spocwd 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.
