Glare & Night Driving Problems in Boston

“Eyeglass wearers often complain that glare can be a real source of night driving problems, “commented Boston Ophthalmologist Francis D’Ambrosio, Jr., M.D. It is generally accepted that 8-14% of light is lost due to reflection off eyeglasses that creates glare, leading to loss of visual acuity and clarity. A result of decreased light is lower contrast sensitivity which affects the patient’s ability to discriminate different shades of gray or objects against a low contrasting background. Eyeglass wearers driving at night are exposed to distracting glare from oncoming traffic and street lights that cause a reduction in visibility. Patients who are not wearing non-glare lenses and driving at night in the presence of extreme glare can see 2 lines less on the Snellen chart (the chart with the big “E”). This glare decreases reaction time to unexpected situations and the ability to identify people or objects. In a study of the visual reaction time while driving at night, the following findings were observed.

Patient                                         No Non-Glare Lenses     With Non-Glare Lenses
Patient with Myopia (-) Rx             10 seconds                             5 seconds
Patient with Hyperopia (+) Rx          8 seconds                             6 seconds

Because the glare from light is eliminated, the wearer has an improved field of vision by 30% and better contrast to see people or objects better. Because non-glare improves reaction time during unforeseen situations, it makes you a safer driver. 70% of drivers prefer non-glare lenses, 89% of highway patrol officers chose non-glare lenses. Will you choose non-glare lenses with your next purchase?
