The RAC has issued a stark warning to motorists who find themselves increasingly dazzled by oncoming headlights, urging them to get their eyes checked for two specific conditions. The motoring organisation highlights that undiagnosed cataracts and glaucoma could be significantly worsening drivers' perception of glare on UK roads.
Silent Eye Conditions Exacerbating Dazzle
In a recent social media advisory, the Walsall-based RAC consulted with Denise Voon from the College of Optometrists. She explained the critical link between age, eye health, and glare sensitivity. "As you get older, you can be more prone to certain eye conditions, such as cataracts and glaucoma, and this can make your perception of glare a lot worse," Voon stated.
She emphasised the importance of regular optometrist visits, as these conditions are often symptomless in their early stages. Early detection and treatment are therefore vital for both eye health and road safety.
The NHS describes glaucoma as damage to the optic nerve, primarily affecting those over 50. Cataracts involve a clouding of the eye's lens, leading to blurred vision and sight loss, typically in older adults.
Beyond Eyesight: Other Causes of Headlight Dazzle
The RAC notes that the problem may not always stem from the driver's eyes. RAC Senior Policy Officer Rod Dennis outlined several other key factors contributing to the modern glare issue.
He pointed to potential headlight misalignment, where an incorrectly set lamp can scatter light dangerously. A major shift is also attributed to changing technology: the widespread replacement of traditional halogen bulbs with brighter, whiter full LED headlights.
Dennis also warned against the use of illegal retrofit LED bulbs, easily purchased online but known to create excessive dazzle. Furthermore, the growing popularity of taller vehicles like SUVs can cause problems for drivers in lower-sitting cars, exacerbating the angle of glare.
Call for Government Action and On-Road Testing
In response to growing public concern, the RAC has formally called on the government to review the issue of headlight glare. It is understood that on-road tests have already been conducted, with recommendations expected to be published before the end of 2026.
This move underscores the recognition that the problem is multifaceted, involving vehicle design, regulation, and driver health. For now, the RAC's primary advice remains clear: if headlights consistently blind you, booking a comprehensive eye test should be your first port of call.
