Glare Recovery

Many drivers report glare reduction and improved photo stress recovery times that contribute to improved night driving ability. When photo stress glare recovery time is improved by just one second when driving 60 mph, vision is restored 100 ft sooner.

Glare can make night driving particularly dangerous because those sensitive to glare can become “temporarily blinded” and driving in rain compounds glare issues. Click the image below to see an enlarged view.

Glare Recovery Time Example

Imagine driving at 60 mph with your eyes closed for five (5) seconds. You would travel 440 feet during that five (5) second period. Click the image below to see an enlarged view.

Now, imagine being “blinded” by an oncoming car with bright lights. One study (Stringham and Hammond 2007) demonstrated that recovery time from glare (photostress recovery) could be reduced as much as five (5) seconds by increasing macular pigment (Zeaxanthin and Lutein) via supplementation.
