Frequently Asked Questions about Sunglasses
No, the amount of UV protection is not dependent on lens darkness. Some lightly tinted lenses can block 100% of UV rays. Darker lenses, however, may provide greater comfort depending on the light sensitivity of your eyes.
During the day, absolutely! The right sunglasses offer clearer, safer and more comfortable vision while driving by reducing glare and improving visibility. Wearing sunglasses during the day also allows your eyes to adapt to the dark more quickly.
Light is made up of waves that travel in different directions. Vertical light helps us see and is useful to the human eye. Horizontal light, however, creates glare. Glare is concentrated light that’s reflected off a shiny horizontal surface, such as water, snow, glass, or the blacktop on roads. It reduces visibility and makes your vision difficult, uncomfortable—and possibly dangerous—as you drive, cycle, ski, or even just sunbathe.
Polarized sunglasses block virtually all glare. The vertically-aligned polarizing layer inside a polarized lens doen’t allow horizontal light to pass through. Driving is safer with polarized lenses, because when drivers can see clearly, they react more quickly to everyday driving hazards. With this anti-glare property, you can wear polarized lenses every day and enjoy all your activities in safety and comfort.
Spending long periods outdoors without proper eye protection can lead to skin cancer on the eyelids and around the eyes. It can also contribute to damage and diseases such as cataracts. And since ultra-violet light is scattered around the sky, staying out of direct sunlight does not fully protect you. Polarized sunglasses consistently surpass all international safety standards for protection against UVA, UVB and UVC radiation.
Different lifestyles, occupations, and activities require different frames and lens features. Matching your needs with the right kind of eyewear not only increases your comfort and protects your vision, it can also enhance your performance in daily activities or on the job.
