Here's an example of a thread from a forum discussing some of the benefits of Hi-Viz  - and whether or not high visibility gear in different types of instances.

The writer explains: Hi vis is not necessarily the 'safest' method of visibility for objects moving at high velocities.


Why is hi-viz used for construction workers and not their trucks? Because they aren't moving much by comparison to vehicles.

Now, what do they do for vehicles that are in motion in areas that are extremely hazardous or dangerous?

They add CONTRAST and SHAPES OR PATTERNS which are disjointed from the shape of the object.

Because when those objects are in motion, it becomes obvious due to the contrast and the shape/pattern moving through space.

The color (of the hi-vis apparel), actually, doesn't make too much of a difference.

A black & white patterned kit will have just as much visibility to the human eye as a hi-viz one when it is placed on an object in motion at some discernable velocity. A black & white patterned kit will have less visibility than a hi-viz one when the object is in low-speed, minimal activity.

Motion is detected with the RODS in your retina, not the cones, and more importantly through utilizing perceived CONTRAST, not color.

Why do you think the best snipers in the world are color blind? Because they're able to see contrast quicker, no colors to distract their vision.

Why do you think the military (of any country) prefers soldiers who are color blind? Because they can detect movement in even the best camouflage, they are not distracted by color but focus on... guess what... CONTRAST.

Why do you think the world's greatest predators (non-human) see the world in greyscale or black&white? CONTRAST!

What do you think? Is he correct?







 









The Brilliant Series from ML Kishigo

The Brilliant Series line of high-viz workwear is the premium line for ML Kishigo, and the safety enhancements they provide far outweigh the premium you’ll pay over standard hi-viz. For example, the Brilliant Series Economy Vest is up to 60% brighter than its standard counterpart when viewed at a distance. When comparing their suggested retail prices, that equates to only 3 pennies for every percent of increased visibility. They calculated the remarkable affect by analyzing a 1080i HD video frame at the distance of approximately 30 to 60 feet. By zooming in and mapping out the identical area/proportions for both vests (Brilliant Class 2 vs Standard) they measured the individual visual footprint of each. This is based exclusively upon luminosity of the cars headlights hitting the reflective material.

Luminosity Comparison, Brilliant Series vs StandardThoroughly measuring the gray levels pixel by pixel, then taking the average across the entire area of each image, you can see that the Brilliant series has up to 60% more of a visible footprint at night.

When comparing the histogram graphs (left side shows level of black, right shows level of white, with every level of gray in between), across the charts there are much higher numbers of pixels for each level of gray all the way up to white, and a significantly lower levels of black pixels with the Brilliant Series than with the standard.

Go to HiVis Supply for the very best from ML Kishigo, and the very best for your workers. They can’t afford not to wear the best and the brightest.
