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 for clear Vision

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.
