December 21 at 9:27 pm marks the winter solstice for the Northern Hemisphere. That’s when the days will start to get longer. This means more difficulty with night driving. Have you noticed a lot of glare with oncoming headlights? Do those LED headlights drive you crazy? Well, you’re not alone. But what is causing this difficulty with driving at night?Stop lights showing a glare at night

A major cause of glare driving at night is CATARACTS! In the dark, our pupils get larger and this allows more light to hit the lens behind the iris (colored portion). These are normal changes, but if you feel unsafe, please have your eyecare professional evaluate the lens for “cloudiness”.

Another common cause is DRY EYE. Just as the lens can be cloudy from cataracts, the front surface of the eye can become more cloudy when it’s dry. Artificial tears can help as a start, but if it’s not helping enough, other dry eye treatments are available. Treatments can vary from person to person so it’s important to have a complete eye exam with a focus on dry eye testing.

Uncorrected refractive error. This just means your glasses are not updated and the prescription is wrong. Lights will appear to have starbursts and it can make night driving difficult as well. Older glasses can also be scratched with outdated coatings, which can make it even worse.
