With it being Road Safety Week we thought we would feature the very latest technology in prescription driving lenses
Those driving for long periods, especially at night time, may feel visually insecure due to the reduction of their visual capacity. Night myopia is a phenomenon that affects one out of three wearers. It causes a loss of their ability to focus on distant objects at night.
AFAR-SV has a specific night vision zone in the upper part of the lens that helps compensate for the refractive error difference that occurs between day and night by up to 0.25D. This provides the wearer with superior visual acuity, reducing stress and visual fatigue so common when driving at night. Not to be underestimated, AFAR-SV design incorporates Norton-SV Digital HD design, providing extremely good visual quality at every point on the lens from the centre to edge, regardless of the prescription or frame selected.
AFAR-SV design can be further combined with VISTA-MESH lens material for outstanding night driving performance.
All AFAR variants come with RF coating, a choice of either regular emerald reflex or blue – considered by some to be advantageous for night driving.
Driving lenses Q & A
“Yellow ‘Night Driving‘ lenses have been shown to provide no benefit in seeing ability at night. They are even hazardous, because they give the driver a feeling of seeing better, which no one has yet been able to explain. Studies have shown that they actually impair visual performance and retard glare recovery
Too much exposure to blue light at night suppresses the secretion of melatonin, a hormone that regulates sleep cycles. … As scientists learn more about potential problems of blue light, blue light blocking glasses have gained popularity as a way to subdue digital eye strain and avoid disrupted sleep cycle.
These glasses can let more light in and also help to reduce glare from oncoming traffic and other light sources. … While often marketed specifically for night driving, polarized or UV (ultraviolet) lens glasses can actually be hazardous when used at night, as they can block too much light coming in
Although gray and green lenses have their own benefits, and colorful lenses are fun, copper and amber tints increase contrast, making them the best options for driving. If you’re looking for a crisp, clear view, we suggest finding a pair of shades with amber or copper lenses – and extra points if they’re polarized.
Polarised lenses are a great way of dealing with glare on a bright sunny day. But not recommended for use when light levels are poor.
