A helmet is indisputably the main element of protection, but what happens if it does not have a visor?
Part of the visor can be considered passive protection, because it is he who is responsible for the comfort of the motorcyclist in a headwind. It primarily protects the eyes, prevents stones, insects, rain / moisture and other troubles from getting into the face that may be encountered along the way, depending on weather conditions.
Traditionally, motorcyclists use a transparent and tinted visor, the former for driving in the dark and the latter on sunny days. However, more and more variants of different colors appear on the shelves. What are they needed for?
In addition to protecting against external factors, the visor’s task is to provide perfect visibility. In other words, a good visor that does not distort the space around the driver and does not strain his vision. What else can you call a visor? This is a lens. Curved lens.
To call the visor completely optically neutral is difficult, because the curved shape will somehow no-no yes distort the space around the edge, but this does not apply to models with a wide viewing angle. And to be completely honest, the lion’s share of the distortion depends on the materials and …. the color of the glass.
Every motorcyclist has a simple and uncomplicated transparent visor. It is used when the brightness of the lighting does not interfere with tracking the road. It is especially relevant at night. The transparent visor is the basic equipment of almost all helmets. Visors of other colors are usually purchased separately.
The second most popular option, which is needed in bright light. Tinted visors can be of different shading levels, and there are also options with a transition – partial tint. It is customary to measure tint as a percentage of transmitted light.
Tinted and mirrored visors are not recommended for use at night, because their functionality is designed for daylight hours, and the amount of light transmitted by them is not enough.
Perhaps the trendiest of all are the mirror visors. Their coating attracts attention and makes the helmet visually very elegant. The point of using such a visor is not beauty, as one might think. The essence of the device is in the reflection of a light wave of a certain spectrum, while a conventional color visor simply refracts light through itself.
Earlier we talked about changes in color and visual perception. This also applies to color visors.
Mirror visor, reflecting a certain wave of light, does not let it pass through itself. The remaining waves reach the driver’s eye and the perception of the color of the surrounding space is distorted. Further, it is quite logical to guess into which spectrum the selected visor will ultimately translate the driver’s color sensation, since some part of the light waves will be excluded.
The blue mirrored visor, reflecting the blue spectrum wave, makes the driver perceive the road in orange-red tones. A similar result can be expected from the green visor as the blue and green waves are close. Yes, here we are again back in the school physics course to plunge into the optics section. Unless through the green visor, the sensation will be closer to yellow tones, while in blue it will still be closer to red.
The yellow / gold visor will reflect the rays of the “warm” spectrum, so through it the surrounding space will be perceived in cool blue and green tones.
The red visor will turn color perception into blue.
Mirror visors “multicolor” or “rainbow” are found in warm and cold versions and work according to the principles described above. If there are more warm colors in the mirror visor, then in the bright sun through it there will be a blue-green world, and if the visor is outwardly in cold colors, then through it the world will be definitely “warmer”.
– Well, with colored mirrors everything is clear. What about a simple silver visor?
The silver mirrored visor reflects the entire spectrum, which means it acts as a darkened one. In general, mirror visors are convenient because they have a tinted effect, which is why they are good for bright sunny days.
How visor color affects road perception
Let me remind you again, a regular color visor and a mirror are a significant difference, even if they make the pilot see the world in the same shades.
– Well, I have a yellow visor, so what? – someone will think.
Have you ever noticed that the fog lights have a yellowish tint? Warm tones, especially yellows and oranges, highlight the topography of the road, as they add contrast to the perception. That is why yellow visors are more suitable for driving at dusk, in fog and during rain, as well as in low sun conditions. Among other things, “warm” visors smooth out glare. But, just a yellow visor at dusk will be more profitable than a mirror one with the same effect, since it has no darkening and allows more light to pass through. On the other hand, the transparent yellow visor blinds the eyes on a fine sunny day, which makes quite a lot of motorcyclists nervous. Way out: have a visor with you to change according to the weather.
The manufacturer wisely says, “Find yours and roll.” And all because it is more convenient for someone to see the road in blue or greenish lighting, a matter of personal preference. In the frank sunshine, motorcyclists are pleased with the feeling of freshness from bluish and greenish visors, and in memory of the contrast of warm colors, drivers choose red shades.
Visor color and shading relieve eye strain and reduce driver eye fatigue
The main thing is to choose a visor that will not only be functionally beneficial in everyday life, but also facilitate driving at one time or another of the day, without straining the driver’s eyes.
