When I discuss night vision driving glasses herein, I am talking about the simple sort of inactive glasses, that seem like a special form of sun glasses, not the active type of night vision goggles developed by the armed forces to allow military personnel to see in pitch darkness.

Night vision driving glasses are becoming ever more more popular as a result of auto manufactures and car owners are installing additional lights and brighter lights on their cars and this increases glare from nearing vehicles.

In addition, the modern technology practices in vision components and coatings mean that present day night vision driving glasses are becoming more advanced and have improved performance.

If you have been undertaking investigations on the Internet about night vision driving glasses, you could have seen reports that the yellow sort should be avoided since they cut the degree of light entering the eyes.

Anayway, if that is fact or not is perhaps a subject for further research and will be strongly influenced by the specific company and type of night vision driving glasses. Nevertheless let me mention something to argue against that claim.

Let let me pose you a straightforward question. If racing car drivers make use of night vision driving glasses to drive quicker, why should people declare that they ought not be worn by the regular driver? Well, one particular night vision driving glasses specification was produced particularly for the worldwide renowned 24 Hours of LeMans sports car endurance race to increase the racing car drivers' speed.

Not only are they worn for the Le Mans, but TAG Heuer - creator of top quality sports watches and chronographs since 1860 intends to advertise their purpose-made "Night Vision" driving glasses through actual racing car drivers such as Formula One racers and Indianapolis 500 racer. And these night vision driving glasses are amber tinted glasses.

If you believe the persons who criticise amber colored driving glasses or not, there is always a different alternative. Clear - not amber colored - night driving glasses.

These types of glasses include a unique anti reflective (AR) outside layer that the producers assert actually improve the level of light passing through, not decreases it. Accordingly it could be useful to explore these prior to deciding not to try any kind of night driving glasses.

The exclusive layer on the clear type of night vision driving glasses is normally created from zircon and silicon, which in addition reduces internal reflections in the lenses.

Select and buy the two differing kinds of night vision driving glasses.

A night vision device is an optical instrument that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies, but are available to everyone. The unit includes an image intensifier tube, a protective and most likely water-resistant housing, and some type of mounting system.

Night vision devices gather existing ambient light (starlight, moonlight or infra-red light) through the front lens. This light, which is made up of photons is then changed to electrons which  are then amplified through an electrical and chemical process. The electrons are then hurled against a phosphorus screen that changes the amplified electrons back into visible light that you see through the eyepiece. The resulting image will now be a clear green-hued amplified re-creation of the scene you were observing.

The resulting image will now be a clear green-hued amplified re-creation of the scene you were observing.

A Night Vision Device can be either a 1st, 2nd or 3rd generation unit. What this stands for is what type of light intensifier tube is used for that particular device.  The light intensifier tube is the heart and soul of an NVD. The classification was initially introduced by the US manufacturers through the US government. European manufacturers do not abide by it

First  generation devices are currently the most popular type of night vision in the world and are passive devices that rely on ambient light and not an infra red source. A first generation device will amplify the existing light several thousand times letting you clearly see in the dark. These units provide a bright and sharp image at a low cost, which is perfect, whether you are boating, observing wildlife, or providing security for your home. They are though quite bulky and require moonlight to operate properly.

Second generation devices are  used by law enforcement or for professional applications. This is because the cost of a second gen unit is approximately $500.00 to $1000.00 more than a first generation device. They feature a much improved image intensifier resulting in a much brighter image, especially around edges of the lens. This leads to increased illumination in low ambient light environments, such as on moonless nights.

Third generation is the latest in night vision technology. By adding a sensitive chemical, gallium arsenide to the photocathode a brighter and sharper image was achieved. In addition, the inside of the device is coated with an ion barrier film for increased tube life. However, it is much more expensive. A third generation device is likely to cost more than $3000.00.

Fourth generation devices (Classified differently by the US Military) differ from third generation allowing the device to adapt instantaneously to changing light conditions. They also have  significant improvement in contrast level and in performance under all light conditions, and consequently  represent the top of the line performance in the night vision market. Price will also reflect this.

Infra-Red Illuminators

All  scopes the above need some form of light to amplify either from the stars or moon. In complete darkness you would not be able to see. Many devices therefore have an in built infra-red illuminator. They work by sending out a beam of infra-red light that is not really visible to the naked eye but the device can see it. This allows the device to operate in total darkness. But just  like a flashlight beam,  the distance you can see with it will be limited by the strength of the infra red beam, usually a maximum of 100 yards with the most powerful types.

How Far Can You See

There are many things that can affect the distance that a night vision device will be of use. Obviously the larger the object, the easier it will be to see. A boat in the water will be much easier to spot than a rabbit in the undergrowth. Also you need to consider how much detail are you trying to see? Often you will be able to detect movement but not determine exactly what moved. Lighting conditions will also affect how far you can see. You will see amuch greater distance under a full moon than say a new moon and a lot more than a cloudy night when there is hardly a star in the sky. Most devices at an economic price will allow you to differentiate between a man and a woman or a dog and a deer at up to 100 yards but you will also probably see a something as large as a barn or hose at 500 yards over open fields.

The purpose of the device is to see in the dark not to act as a pair of binoculars or sniper’s sight.
