What Are Polarized Glasses?
Polarized sunglasses are an excellent choice for people who spend a lot of time outdoors. Polarized glasses fight glare, making it a lot easier to see on sunny days. Glare generally occurs when light waves bounce off reflective surfaces like lakes, snowy mountains, or shiny objects. Since the surface is horizontal, the light is reflected horizontally.
Polarized glasses have a special chemical applied to their lenses to filter light. The chemicals work to block some of the light that passes through the lens. The lenses on polarized glasses work to prevent light glare from hitting the sunglass wearer straight in the eye. The filter on polarized glasses is vertical. This allows only some of the light to pass through the openings. Since the light from glare is generally horizontal, polarized glasses block this type of light, only allowing vertical light in.
People who work outdoors love polarized glasses, so do athletes who compete outdoors like runners, cyclists, golfers, and rowers who rely on polarized glasses to see their path clearly. The filter is vertical with polarized lenses, so only some of the light can pass through the openings. Because glare is typically horizontal light, polarized lenses block this light and only allow vertical light. The horizontal light is blocked by polarized lenses, which helps eliminate glare from shining directly into your eyes.
