Polarized Sunglasses - optical4u.com
What makes polarized sunglasses so unique is the fact that they have lenses with anti-reflective coating that blocks the brightness as well as glare reflecting off surfaces. The nice thing about choosing this kind of eyewear is that it enhances your vision by making colors appear more vibrant and clearer. Their main purpose however is to reduce glare from the light that happens to be bouncing off a surface such as water or a road or even metal. When you put them on, these polarized shades will improve your visual clarity and they will make things more comfortable in bright conditions.
