Glare can come from all sorts of sources. From lowlight in the spring to the reflection of light on wet roads, reflections off windows and even from objects in your car that catch the light.
It causes our pupils to try to rapidly constrict (get smaller) to adapt to the light source, which is what produces the temporary blindness associated with glare.
At night, our pupils are already dilated to adapt to low light. This means our eyes have to work harder to constrict the pupils when faced with bright headlights and street lighting. And problems with glare can also worsen with age as our ability to adapt to light and dark situations slows down.
Why is glare dangerous?
The danger comes in those moments when you can’t see or when one part of the road is thrown into dark shadows while the rest is flooded in light. What’s more, even if you aren’t affected by the glare, other drivers might be more susceptible to it, so it’s always important to keep the possibility of glare in mind whilst driving.
But particularly during winter, a host of conditions in darker, wetter weather can combine to create glare at any time of day causing temporary blindness – and that can be difficult whilst driving.
Fortunately, if glare is impacting your ability to drive safely, then there are specific anti-glare driving lenses you can get for your glasses, as well as some lens treatments for glasses that can help.
Specsavers in Devon can help with solutions
If you’re driving in daylight, polarised lenses might be a good option as they eliminate glare from horizontal surfaces such as roads, water and snow. They also offer 100% UV protection, improve contrast and help ease the strain on your eyes so they are particularly good for driving in bright conditions.
If you already wear varifocals or use two pairs of glasses, one for distance and one for close up, then SuperDrive varifocal lenses with UltraClear SuperClean Smart treatment, designed to reduce reflections and dazzle typically caused by the wavelengths of light emitted from headlights and street lighting, could help.
Other options such as tinted lenses or our Reactions photochromic lenses — which react by darkening when the light is bright — may also be helpful.
