Sunglass designers living decades ago were creative enough that they had developed a couple of classic frame styles, which are provided by modern manufacturers as a special category called retro vintage sunglasses. Cat eye sunglasses, bug eye sunglasses and 80s oversized sunglasses are some of the examples of retro sunwear products that are regaining popularity among the average. For a majority of target customers, this is reminiscence. While most of them resort to these retro sunwear products for re-experiencing their classic style and appearance, there are actually additional benefits that are made available by modern manufacturers. During the past decades, lots of improvements and breakthroughs have been made and most of them are absolutely feasible to be used in retro sunwear styles. The combination of a retro frame style and an advanced lens technology brings greater benefits to modern customers.
The main purpose of this article is to list some of the latest lens technologies that have been applied to retro vintage sunglasses. Photochromic lenses may probably be the most advanced form of sunglass lenses until now. What is the effect of these lenses when they are fitted into a retro frame? Well, these lenses are auto-adjustable that they will lighten and darken in changing light conditions. These retro sunglasses will function well during outdoor activities lasting several hours because when weather conditions change or the sun begins to set, they can automatically adjust the amount of light that can enter the eyes. Another advanced lens technology that can be used in retro sunwear is polarization. Polarized sunglass lenses contain a special filter that can selectively filter out horizontal light reflected from smooth surfaces, reducing dramatically glare.
Moreover, retro vintage sunglasses can also utilize different types of lens coating. Anti-reflective (AR) coating applied to the back lens surface will help eliminate glare when the sunlight is behind. In other words, this coating prevents sunlight reflection from the back surface of sunglass lenses. Another helpful coating is called mirror coating. Applied to the front surface of the lenses of retro sunglasses, mirror coatings can block an additional 10 percent to 60 percent of visible light, enabling wearers to experience more comfortable vision.
