What are polycarbonate glasses?

polycarbonate is a formable, durable and cheap form of plastic, which is used in a wide range of consumer products. They are often used to make lenses of glasses, compact discs (CDS), domestic goods, drinking glasses, water and bottles and numerous industrial products. Polycarbonate is awarded for its impact resistance, optical cleanliness and temperature tolerance. Polycarbonate was developed in the 1950s and was soon recognized as a dynamic replacement for glass. In the age of 80, consumers were introduced by polycarbonate glasses as a safe and available alternative to standard plastic or glass lenses. In addition to their excellent impact resistance, polycarbonate glasses are up to 40% thinner and one third lighter than standard plastic lenses. These features cause polycarbonate glasses are ideal for people with high regulations. However, polycarbonate glasses are perfect. As a result of their ability to absorb the impact, the lenses are soft and therefore more susceptible to scratches. To compensate for it wereDeveloped scratch -resistant coatings and can be added to polycarbonate glasses to ensure added durability.

All safety wear is made of polycarbonate material because it provides the best resistance to any available glasses. Polycarbonate glasses are more resistant to breaking than plastic lenses. Polycarbonate lenses are highly recommended for children because of this safety benefit. In addition, polycarbonate blocks 99% of the UV light. This ability is an important feature, especially for children and individuals who work outside because it is known that UV light contributes to the development of cataracts.

Although the safety features of polycarbonate for glasses are indisputable use of polycarbonate in consumer products has been questioned. Polycarbonate used to produce objects such as baby bottles, polycarbonate drinking glasses and reusable LWater reeve, contains chemicals called bisphenol-a or BPA. In 2007, an independent group of scientists reviewed a set of data available on BPA security and found that polycarbonate products made with BPA were security concerns for people. The bottle immediately reacts by removing the production of BPA -containing products. Although there are no restrictions on the use of polycarbonate in glasses and bottles, the use of this material in food containers has dropped. Since September 2008, US food and drug administration has resisted BPA products and has claimed that additional material safety data is needed.
