In some situations, this can deteriorate into nyctalopia or night blindness. As convenient as all our electronic devices are, they wreak havoc on our eyes. These devices emit blue light which can cause eyelid twitching, eye strain, fatigue and even headaches.
Besides the fact our vision changes as we age, driving conditions have also changed over the years. In addition, our reaction times are slower. Coupled with the fact it becomes more difficult to gauge distance. All this translates into not seeing that pothole or deer leaping out from nowhere in time. It can take up to 20 minutes for our eyes to fully adjust to dark conditions.
The challenge is when they need to adjust between bright lights and darkness. So, your vision is used to the blackness of the evening. When you see headlights or streetlights, your eyes have to quickly adjust.
That being said, city driving also poses problems. Unlike natural light, our eyes can be overwhelmed and miss things. Some other tips that will help improve your night vision as well as glasses are:.
Some women are into jewelry, purses or shoes. My wife loves her sunglasses and owns at least a half dozen pairs of Eagle Eyes. As a child, she was near-sighted wearing thick prescription lenses. After corrective eye surgery, she became far more conscious of protecting her vision. She has owned, at some point, almost every brand of sunglasses out there!
She determined Eagle Eyes are amongst the highest quality of manufacturers and, consistently, less than half the price of the other big-name brands. At least until I tried them on! To my astonishment, they made everything brighter and the clarity was remarkable. This was especially true with highway driving and trying to keep an eye out for wildlife. Another thing I noticed was the difference they made when road conditions were rainy or snow covered.
The best part, no more squinting at oncoming traffic. For me, it really does make a difference! Vision Center ranked them in 2 nd place, although I personally prefer Eagle Eyes and all they stand for. Check pricing and availability on Eagle Eyes website.

Many older adults actually avoid or minimize traveling after dark. Regular glasses lenses block about 8 percent of the available light, only allowing about 92 percent through to the lens. Glasses with AR coatings allow nearly all the light in, Glasses with AR coating promote sharper vision.
They can also appear more invisible and seem less obtrusive than regular glasses. New and advancing technologies are improving glasses regularly. New technologies involve high-definition eyeglass lenses that are specially designed to correct vision issues and higher-order aberrations. These glasses enhance and sharpen vision in every lighting condition. As such, they can improve night vision and therefore night driving.
High-definition glasses can sharpen vision, reduce glares, and let in maximum amounts of light. Examples of high-definition eyeglass lenses include free-form and wavefront lenses. High-definition and glare reducing lenses are more advanced, specialized, and typically about a quarter to twice as expensive as traditional eyeglasses.
Many glasses are marketed that claim to enhance night driving, most without a prescription. These typically include polarized or UV ultraviolet lenses. These glasses are often initially designed as sunglasses meant to block out harmful sun rays and help people to see better in the sunshine. UV and polarized glasses usually have a yellow or blue tint to them. Headlights and streetlights are not the same as sunlight, however, and these glasses may actually be dangerous to wear at night.
Polarized and darkened lenses can block out too much light at night and make it harder to see. They will not just decrease glare, but they may make it even more difficult for your eyes to adjust to faraway lights or changing light conditions. At night, your eyes need to be able to make as much use out of low light as they can. Polarized and UV lenses just serve to block the light, not enhance it. In fact, even yellow lenses reduce the overall visible light to a degree, since they also block some blue light.
This might be a good thing during the day, but not at night — when maximum visibility is key. Researchers at Harvard's Schepens Eye Research Institute recently conducted a study to find out whether night driving glasses provided any visual benefit for nighttime driving. All 22 of the participants "drove" in four simulated night-driving conditions, wearing either yellow-tinted night driving glasses or glasses with clear lenses.
Each participant also drove in scenarios with and without a headlight glare simulator activated, to mimic the effect of oncoming traffic. In each scenario, participants' reaction time to seeing a pedestrian walking alongside the simulated roadway was measured. The study found that night driving glasses did not appear to improve :.
In fact, the results found "that wearing yellow-lens glasses may slightly worsen performance," but the finding "was not statistically significant. Start by scheduling a comprehensive eye exam with an eye doctor. Many people who think their vision is fine are surprised to find out how much clearer they can see at night, even when a small amount of uncorrected refractive error is corrected with new glasses. If your eyes are healthy and you don't have vision problems that need to be corrected with prescription glasses, then the best glasses for night driving are no glasses at all.
On the other hand, if you need prescription eyeglasses because you have nearsightedness , farsightedness or astigmatism , choose clear corrective lenses with an anti-reflective AR coating. Reduce or eliminate the glare-causing reflections of streetlights and headlights within your lenses.
