Night Vision Glasses

Driving at night can be difficult, but night vision glasses make it much easier.

These are not army issue night goggles that let you see in total darkness.

Just special glasses that cut the glare from oncoming cars and other light sources.

As car manufactures use brighter lights to help you see the road better, they are creating a hazard for drivers. Many car accessory stores offer these lights as aftermarket parts to help you ‘trick your ride’, and to see better after dark.

New optical technologies meet the hazards of these new lights with more sophisticated and more effective night driving glasses.

It is a myth that effective night vision glasses have a yellow tint lens.

Driving at night also causes excessive eye strain, because of reflections and the halo effect of lights, especially lights in the rear view mirror. Suddenly changing from a brightly-lit street to a darker one forces your eyes to readjust to the varying levels of brightness. Driving in the county without any visible scenery can also cause your eyes to become very weary and stressed.

All of these additional strains on your eyes results in nearly four times more accidents at night than during the day.

Yellow tinted night vision glasses

It is a common misconception that glasses with a yellow tint or polarized with a yellow hue are the best glasses for driving at night. The idea is that the yellow color will reduce glare and improve contrast. In reality, though, when driving at dusk or at night with limited outside light, any tinting will further reduce your vision. The yellow tint makes many people believe they are seeing better, when actually it is just the opposite.

Yellow tinted night driving glasses have been proven to provide no benefits whatsoever. They are actually considered more hazardous than not wearing any glasses at all. For reasons no one has been able to explain, the wearer feels as if he is seeing better, when actually he is not. Studies show these glasses impair your vision by reducing reaction times and glare recovery.

Night vision glasses are popular for huntng.

Producers of these yellow tinted glasses promote them with unfounded claims of improved night vision, often through mass mailing campaigns. The Federal Trade Commission has ruled these promotions and practices as illegal, because the glasses do not do what the promotions claim.

Yellow lenses are not all bad. They may be somewhat effective in foggy or hazy conditions, during the day. But, they do not have any benefits at night. They are ineffective against the glare of headlights and should never be used at night.

If you are extremely bothered by headlight glare, the first thing you should do is have your eyes examined. Problems seeing at night could be an early indication of medical problems or cataracts.

To help you see better at night, you should opt for a good pair of night vision glasses with clear lenses. These glasses have a special anti-reflective (AR) coating. The AR coating is a special type of optical coating that is applied to the surface of the lenses, to reduce reflection.

The glare is reduced, because the internal reflections are minimized. This reduces the halo effect headlights can cause. Also, the AR coating increases the light transmitted through the lens to your eye. The main reason we don’t see as well at night is because our eyes do not get the light they need to reflect images inside our eyes.

It is important to remember, if you do not normally wear prescription glasses, night vision glasses, even the ones with AR coated lenses, will not necessarily improve your ability to see better at night. But they can dramatically reduce the glare of oncoming headlights, and decrease the annoyance of lights coming up from behind.

To drive safely at night, stay away from the yellow tinted lenses, and get a good pair of night vision glasses with an AR coating.
