Night Driving

Battling with glare at night? You are not alone. Research done by Essilor in the UK shows that 85% of people struggle with night driving. And it has a lot to do with how our eyes are designed.

We are not cats. Cat retinas have evolved to give cats superior night vision for hunting purposes. Cats have a high concentration of rod receptors, which are sensitive to dim light. The human eye on the other hand was designed for daylight and high-contrast vision. The human eye has fewer of these cells in the retina which reacts to low-light. These cells also have a slow response time: sudden bright light disrupts these cells causing discomfort, longer reaction time and lower visual acuity. That makes prowling and navigating the streets of Johannesburg at night a little tricky.

But don’t fret. Recent lens innovation has brought new designs and premium coatings to the market that makes night driving easier.

These new lens product categories ensure reduction of irritation caused by reflected light, increasing contrast at night and this makes judging of distances during night driving easier. The lenses further reduce glare caused by oncoming vehicles; especially LED and Xenon headlights. The nett effect is that the wearer feels more relaxed and confident when driving in the dark; making the streets of Johannesburg easier to navigate at night.
