![]() Glare forces your eyes to work harder while they try to interpret the information they’re taking in. Research indicates that glare from the sun can cause fatigue. Polarized sunglasses may also give you a more accurate portrayal of colours than non-polarized sunglasses. Athletes and outdoor hobbyists often use polarized sunglasses so they can see with a higher degree of precision. Improved ClarityĮven when glare is not a safety issue, it can impact your ability to see clearly. Studies indicate that traffic accidents, particularly intersection collisions, occur more frequently when the sun is optimal to produce glare.īy reducing glare, you can stay more aware of your surroundings, which could help you avoid accidents and injuries. In the best-case scenario, glare is distracting. The Benefits of Polarized Lenses Glare Reduction Some vertical light can pass through the filter, but horizontal light, or glare, is unable to make it through. That is the general idea behind polarized lenses. But if you turn the popsicle stick sideways so it’s horizontal, it can’t fit between the slats of the fence. You could easily slide a popsicle stick between the slats if you hold it vertically. Think of it this way: imagine a picket fence with an inch between each slat. However, the filter is applied vertically, so vertical light can pass through, but horizontal light cannot. Polarized lenses are treated with a chemical that filters out light. As a result, glare will still reach your eyes with more intensity than other light, impacting your vision. However, this technology works the same way for all types of sunlight, no matter which directions the light vibrates. ![]() If your lenses offer UV protection, they most likely contain special dyes and pigments that absorb ultraviolet rays, preventing them from reaching your eyes. Non-polarized sunglasses are designed to reduce the intensity of any light. The difference between polarized and non-polarized lenses is how they handle glare. We call this concentrated light, “glare.” ![]() This process is called polarization.īecause the light is only vibrating in one direction, it becomes concentrated, hitting the eye directly. ![]() But when light bounces off a horizontal surface like snow, water, or the roof of a car, it only vibrates in one direction, horizontally. Normally, light vibrates in multiple directions. Light travels in waves, which means it vibrates. What’s the Difference Between Polarized & Non-Polarized Lenses? Today, we are looking into the science of polarized lenses, including what they do, what they don’t do, and whether they’re worth the price tag. What does that mean? Will polarized lenses protect your eyes from ultraviolet light too? Excessive and ongoing exposure to UV light is linked to diseases like cataracts, glaucoma, and age-related macular degeneration.īut what about polarized lenses? It’s not uncommon to see the word “polarized” next to “100% UV protection” on the tag for a new pair of sunglasses. Super early bird pledges start at $249 for Dusk, or $179 for Dusk Lite, with shipping due to begin in August if all goes to plan.Ĭheck them out in action in the video below.At this point, it is hardly a secret that sunglasses are about more than simply looking stylish and feeling comfortable.Ī good pair of sunglasses is essential to your health they filter out harmful ultraviolet rays. It may all be a case of “if it ain’t broke …” but Dusk might appeal to tech heads looking to make that moniker literal.Īmpere is currently funding Dusk on Indiegogo, where it’s already absolutely smashed its US$15,000 target more than 10 times over, with 24 days remaining on the campaign. Skugga even tried the app-controlled tint, but cancelled the Kickstarter campaign before too long. Researchers have also experimented with solar cell lenses, or talking glasses that alerted you when you've had enough Sun. Bose has crammed fancy speakers into specs, and even attempted augmented reality, while Intel and Oakley packed in a fitness tracker. Sunglasses have been rich fodder for startups to cram tech into, and Dusk is far from alone in that arena. Dusk has a water resistance rating of IP65, which Ampere is quick to call “waterproof” but officially means you shouldn’t submerge them at all. In terms of battery life, the company says you’ll get seven days out of Dusk using just the tinting features, or four hours of continuous use of the speakers. Using the app you can make the specs cry out like a Tile tracker to help you find them. That speaker can also come in handy if you lose them. ![]() The speakers are “open ear,” but Ampere says that only the wearer will be able to hear them. But the regular Dusk model also throws in some speakers and a mic, for taking phone calls hands-free, summoning Siri and Google Assistant, or listening to music and podcasts. If that’s all you’re after in a pair of smart sunnies, the Dusk Lite model is probably enough. ![]()
