Yellow Glasses for Night Driving

Going out on the road at night or on a rainy or cloudy day,
many people, although they know how to drive very well, do not give them
security. A great help is to wear yellow glasses.
We all know that if we are outdoors on a sunny day,
sunglasses help reduce glare and protect from sun shine. In contrast, on dark
days, sunglasses increase the contrast and help you see well, especially if the
glass is yellow.
The visual acuity is necessary to achieve a good three -
dimensional view without the perception is very difficult to coordinate the
direction of depth, evaluating the distances or calculating trajectories and speeds.
This poor vision can have as a consequence faults in the
braking distance and cause accidents, so it is very important to take it into
account when going out to drive.

The yellow color in the lenses absorbs , or eliminates, the
light blue , the violet and partially the green; It increases the contrast and
the amount of visible light so that they increase the depth of focus and that
helps to see better.
Therefore, glasses with yellow crystals are effective in low
light, on cloudy days or during the night , since their function is to
increase, in addition to contrast, perception. In this way you can see the
holes in the street better, you reduce eye fatigue and you will feel safer when
driving.
Both yellow and orange increase the contrast because they are
at the center of the visible light spectrum and that is why it is the color
that we see best. For that reason, they are also used for reflective vests,
heavy machinery and even tennis balls.

Yellow Glasses or lenses are widely used by cyclists, triathletes,
drivers, hunters and those who practice shooting because, by improving the
contrast, it helps to sharpen the aim. But they are also suitable for people
with diabetes, problems in the retina or in the macula.
Ophthalmologists recommend using yellow lenses to improve
vision at night or on dark, rainy or cloudy days, and opt for gray or blue
during the day.
The ophthalmologic explanation
The retina is the part of the eye equivalent to the sensor
of a digital camera, that is, where the images that enter through our eyes are
captured so that the brain interprets them and we can see them. It has mainly
two types of cells, the cones that are activated under natural light conditions
and the rods that are activated when night falls and are used to see in low
light conditions.
With the fall of the sun, the retina begins to stop using
the cones to use the canes. If we put yellow lenses in front of our eyes, they
will block the passage of light with bluish components, the predominant type of
light at this time of day, and then the cones will remain active for a longer
time in the face of the appearance that there is still some natural light.
That is why, during the night, the yellow lenses increase
luminosity, improve the contrast of the objects and help us to see well.
