Night vision glasses have enjoyed a huge surge in popularity over the past few years, but are they really safe for driving? Most night driving glasses are designed to be worn alone or over prescription glasses. Drivers report that the yellow or amber polarized or tinted lenses help to cut glare from headlights. Often, users feel that they improve their vision after dark but in fact, the reverse is true. They may be something of a fashion statement, but overnight glasses with colored lenses can actually be detrimental to the wearer's ability to see clearly. Those yellow lenses can sometimes prove to be an effective way to cut glare in daylight if it is foggy or overcast. However, they also reduce the amount of light that reaches the eye and should not be worn after sunset. If the glare from oncoming or passing headlights really is an issue, you should consult your optometrist. This can often be a sign of cataracts or other underlying eye problems that can be corrected with the right prescription lenses
