Saskatoon optometrist Rachael Berger has noticed a rise in the number of drivers expressing concerns about their nighttime vision. According to Berger, many individuals, regardless of age or health, are reporting difficulties seeing at night due to the prevalence of LED headlights on vehicles. She explains that our eyes’ rods activate in darkness to aid visibility, and sudden exposure to intense LED light can be disorienting and uncomfortable, leading to visual fatigue.
Advocates are urging both the federal government and car manufacturers to reevaluate regulations regarding bright headlights. They emphasize the importance of finding a balance between enhancing drivers’ visibility without compromising the safety of others on the road. LED headlights, known to be up to four times brighter than traditional lights, can trigger discomfort glare, causing visual discomfort and fatigue, as highlighted by Berger.
Vehicle lighting expert Daniel Stern warns that prolonged exposure to bright headlights, whether from oncoming cars or through mirrors, can lead to discomfort glare and potentially affect driving safety. Stern advocates for stricter regulations concerning headlight adjustments for both new and existing vehicles to ensure proper bulb compatibility and alignment.
Although Transport Canada updated headlight regulations in 2018 to enhance visibility and address lighting technologies, aftermarket modifications by dealers or vehicle owners might not adhere to these standards. David Adams, president of Global Automakers of Canada, stresses the need for maintaining regulatory compliance post-purchase to prevent alterations that could affect safety.
Stern points out that Canada’s alignment with U.S. regulations has contributed to the brightness issue, lacking emphasis on glare control. Transport Canada is conducting a nationwide survey to gather insights on headlight glare’s impact and plans to collaborate with the United Nations Economic Commission for Europe to address the issue further.
Recent motions by Vancouver and Victoria city councils urge the federal government to address excessive headlight brightness, proposing solutions such as auto-dimming features and adaptable lighting options for various driving conditions. These initiatives reflect a growing political will to tackle the problem, similar to addressing air pollution once the necessary support is in place.
