In recent years, yellow lens glasses have surged in popularity, touted for their supposed benefits in enhancing vision, particularly in low-light conditions. However, as with any trend, it's crucial to sift through the marketing hype to uncover the scientific facts. This article aims to do just that, examining the claims made about yellow lens glasses and what science actually says.
Dispelling hypes about yellow lenses
Great for Night Driving: There's a common belief floating around that yellow lens glasses are the secret weapon for night driving, making things brighter and clearer. But here's the straight talk: science doesn't back this up. While they might make things appear brighter, they don't necessarily improve your night vision or help you see better in the dark. In fact, they reduce the amount of light your eyes see due to the tint. So best stick to the basics for safe night driving: keep your windshield clean, glasses free from smudgies, and your eyes on the road.
Feelin' Brighter: You might see some ads say that yellow lenses are like a mood booster. The idea is they block out the blue light, which if too much, can mess with your body clock and mood. Now, while it's true that getting enough sunlight keeps your spirits up, the whole mood-lifting power of yellow glasses isn’t set in stone. Sure, they might make things look sunnier on a cloudy day, but don’t count on them to replace your morning coffee or a good laugh with your mates.
Reduce Eye Strain: Now, it's true that a lot of us are glued to our screens, and yeah, our eyes get tired. But here's the deal: there's no solid evidence that yellow lenses are the magic solution to reduce eye strain from screen use. They might cut down on some glare, which is cool, but don't expect them to be like some kind of spa treatment for your eyeballs. The best way to fight off screen-induced eye fatigue? Take regular breaks, blink more often (yeah, we forget to do that), and maybe adjust the brightness and contrast on your screen. Keep it real and give your peepers a break the old-fashioned way.
What you CAN expect from yellow lenses
Improved Contrast: Let's talk about how yellow lenses can make things pop, especially when it's foggy, hazy, snowy, or just plain dim, during the day. Yellow lenses got this knack for filtering blue colour spectrum. So how does it relate to improvement in contrast?
It's all about how light behaves when it hits your eyes. Think of light like a bunch of different-sized waves crashing into the shore. Blue light has shorter, more energetic waves. When these waves hit the lens in your eye, they scatter more than the longer, lazier waves of other colors. This scattering can make things look a bit hazy or less sharp – kind of like trying to see through a fog.
Now, when you slap on a pair of yellow lenses, they're like bouncers at the door of a club, specifically keeping the blue colour waves out. By cutting down on this blue light, there's less scattering in your eye. Less scattering means less visual 'noise', and that makes it easier to see the contours (aka: contrasts) between different objects. Sort of like the difference between looking through clear water and murky water.
Handy for when you're driving through mist, cycling on a foggy morning, or hitting the slopes when it's snowing.
Blue Light Filtering: As mentioned earlier, yellow lenses can help block some of that blue stuff, making screen time a bit easier on the eyes and maybe even helping you sleep better.
However, not all yellow lenses are born equal. Different brands offer varying degrees of blue light protection. Look for lens spec with at least 50% filtering around 450 nm - as our phones give off the highest energy intensity at this range. And of course, switch to 'night mode' setting on your phone or computer in the evenings will help.
