BloodVision Eyewear - High Contrast Hunting & Recovery Glasses for Day & Night Use | Enhanced Blood Detection for Hunters | Perfect for Tracking Wounded Game & Trophy Hunting

SKŌPT OpticsSKŌPT Optics has engineered new OptiChromatic lenses to let you see blood-trails better. This patent pending technology is like nothing you've ever seen before. HOW TO USE: BloodVision glasses work BEST in bright sunlight or in the dark with a bright warm flashlight (1900 Kelvin to 4000 Kelvin, WARM colored is better). Glasses should fit close to your face to stop daylight from reaching your eyes around the lens. A hat can help keep sunlight from leaking around the glasses to the eye. The science behind these glasses is that they enhance your color-vision to pass Blood-Red colors and to Dull ground colors. They work both Day and Night; in the daytime they work great with the bright sunlight; at nighttime they work great with a bright LED flashlight. Human color vision is not very good in low-light conditions (like dusk and dawn) so the glasses will be limited in low light conditions. So, if you shoot a deer late in the afternoon just wait for the sun to go down. The glasses have a patented “OptiChromatic” lens technology that helps you see blood better. If you are Red-Green color-blind then you are in luck, because they help color-blind hunters see blood.Two Framestyles to choose from: Tactical-180 and Comfort Fit-Over.MAINTENANCE: To help maintain the OptiChromatic BloodVision lenses, your new eyewear comes with a microfiber wipe and protective case for cleaning and storage. Using them will preserve the superior optical quality of SKŌPT’s lenses.
