No need to take them off when it becomes cloudy or when you enter inside. The only sunglasses you need that perfectly adapt to all weather conditions. How do photochromic sunglasses work? The light-sensitive molecules inside photochromic lenses shift their structure when they're bathed in UV rays, allowing them to absorb more light and give the lenses a darkened appearance. Once the UV light goes away, the process reverses and the lenses become clear again. Regardless of their tint level, photochromic lenses provide complete protection against harmful UVA and UVB rays, ensuring optimal eye safety. Polarized sunglasses have been developed by NASA to protect astronauts’ eyes from space radiation, but these days you’re more likely to see polarized sunglasses on a cyclist, driver, boater, climber, skier or even on a gardener. Polarized sunglasses reduce glare by selectively filtering light. They use a special chemical filter that absorbs horizontally polarized light, which is the type of light that causes glare from reflective surfaces. This filtering process makes it easier to see in bright conditions, especially around water, snow, or on roadways. Here is how they works:
Light waves vibrate in all directions. When light reflects off smooth surfaces like water or a road, it becomes mostly polarized in a horizontal direction. Polarized sunglasses contain a special chemical filter with microscopic slits that are aligned vertically. The vertical slits in the filter only allow vertically polarized light to pass through, blocking the horizontally polarized glare.
Improved Vision: By reducing glare, polarized lenses make it easier to see details, colors, and objects, especially in bright conditions. They also reduce harmful effects of eye strain and eye fatigue. Benefits of Polarized Sunglasses: * Reduced Glare: The primary benefit is the significant reduction of glare, especially from water, snow, and roads.
* Improved Clarity: Polarized lenses enhance contrast and make it easier to see details. * Reduced Eye Strain: By minimizing glare, polarized lenses can reduce eye fatigue. * Enhanced Color Perception: Polarized lenses can also improve color perception and vibrancy.
