Why Use Night Vision Driving Glasses?
Night vision driving glasses are becoming increasingly more popular because
A) Car manufactures are installing more lights and brighter lights on their automobiles, and
B) New technologies in Ophthalmological science mean that night vision driving glasses are becoming more sophisticated and effective.
Driving at night places additional strain on the driver for several reasons and the design of night vision driving glasses should be targeted to address each issue, which include:-
- Reflections and haloes around lights.
- Glare from automobile lights, particularly from the rear view mirror.
- The sudden change of light intensity from bright to dark when street lamps are no longer present, for example on an urban motorway at the end of a brightly-lit major intersection where the road lights suddenly reduce in number, requires the eyes to constantly adjust to the new brightness levels.
- The absence of any visible scenery makes the journey monotonous leading to boredom and fatigue.
- At night, in very dark conditions the focus of the eyes reduces to a distance of about 1m.
It is no wonder that night driving results in four times as many accidents at night than during the day.
The Two Basic Kinds Of Night Vision Driving Glasses
Clear Night Vision Driving Glasses
The night vision driving glasses shown on this page are of the clear type, not tinted.
Many eye care professionals strongly recommend glasses with an anti-reflective (AR) coating. This ultra-thin film, made from zircon and silicon, reduces internal reflections in the lenses. Unlike sunglasses or self-darkening lenses, which block some light, AR-coated glasses actually transmit more light – about 8 percent more. This improves vision at night and helps distinguish fine details during the day. Highway patrol troopers have reported better night and day vision and reduced nighttime glare with AR-coated lenses.
Tinted Night Vision Driving Glasses
Tinted night vision driving glasses are also available with an anti-reflective (AR) coating and with Ultra Violet (UV) Filters. Be careful in your choice of tinted glasses and only choose those that do not significantly reduce the quantity of light passing through to your eyes.
