Glare is known as the loss of visual clarity when the intense light is striking directly to the eyes in a horizontal plane. This irritating glare makes it difficult to see the surrounding objects, causes annoying and teary. Prolonged exposure to blinding glare may lead to vision damage or vision loss. This phenomenon often happens when you are wearing tinted sunglasses in water environments since these shades designed for UV protection only. Thanks to polarized technology, polarized lenses are capable of reducing glare to bring a sharp vision to the glass wearers.

Glare occurs only in reflective places like a lake, river, open water. Sunlight scatters everywhere around us and becomes polarization when it encounters the smooth surfaces. Polarization is a process to create reflective waves in vertical and horizontal positions. Vertical wave is beneficial to the eyes while horizontal wave causes glare. A chemical filter covered on the lens surfaces or inserted inside the lenses can eliminate glare and allow the vertical light to pass through. Regarding UV protection, polarized sunglasses offer the same performance as UV shades.

In the past, polarized shades have been worn primely by fishermen and boaters. Today polarized lenses made in better quality and lower prices, so they are widely used for most outside activities for men and women as more outdoor enthusiasts embrace these practical benefits. Polarized lenses can integrate into most sunglass styles like an aviator, round, sport to meet your fashion sense and various applications.

Polarized sunglasses are easily recognized by looking at labels or noticing "polarized" printed on the sunglass temples.
