Structure Flip-up Flip-up sunglasses have lenses attached to a hinge, so that they can be flipped upward when not needed. The lenses can be individually flippable or have separate hinges. Clip-on Clip-on sunglasses have removable lenses that can be attached to other similar frames. They are ideal for people who have custom-made frames and need different types of lenses for different light conditions. Slip-on Slip-ons are the most common of all sunglasses. They have a fixed frame and lenses, which makes them more durable but allows no changing and can be expensive to repair, Lens color Gray Gray lenses are often called the all-around lenses. They work well under all light conditions. They are especially useful for evening games, because they regulate the harsh artificial lighting. Blue Blue lenses are ideal for bright sunlight. They even out the amount of sunlight that reaches the eyes, which also provides protection against irritation and eye damage. Yellow Yellow lenses are used in low light conditions, such as cloudy days or late afternoons. They enhance the available light and increase the contrast between the ball and the field. Lens Glass Glass lenses commonly make use of crown glass, the same material used for bulletproof windows. They are heavier than newer synthetic lenses and are seldom used in professional or official games. Polycarbonate Polycarbonate lenses are made of a tough plastic designed specifically for lenses. They are very light and offer the best impact protection. Frame Metal These sunglasses have frames made of a light metal, such as aluminum or titanium. They are generally heavier than plastic or carbon-based materials, although not necessarily more durable.
Polyurethane Polyurethane is a type of heavy-duty plastic used in most outdoor equipment. It is very light and durable, making it a popular choice for sunglass frames.
Carbon-fiber These sunglasses are made of a metal or plastic material that has been reinforced with carbon fibers too add strength and reduce weight. They are the lightest and most durable frames in the market. |
