Superior Polycarbonate Glasses

The lenses of polycarbonate glasses are made from the special material of polycarbonate

. Developed in 1950, polycarbonate is a moldable, durable and inexpensive form of plastic. It had soon become a dynamic substitute for glasses. Due to its special features, polycarbonate is used in a variety of products in addition to polycarbonate glasses, such as compact disks, house wares, drinking glasses and baby bottles. Polycarbonate glasses feature impact resistance, optical clarity and temperature tolerance. In the 1980s, polycarbonate glasses were firstly introduced to customers as an affordable alternative.

The lenses of polycarbonate glasses are superior to other forms of lenses in the market. Besides their being ten times more impact resistant to breakage than plastic glasses, polycarbonate glasses are up to 40% thinner and one-third lighter than ordinary plastic glasses. This feature makes these glasses the best choice for people with heavy prescription. However, the polycarbonate lenses are soft and therefore more susceptible to scratches. So scratch-resistance coatings are often added as compensation.

Polycarbonate glasses are highly recommended for childrens use due to their safety benefits. For those naughty kids, polycarbonate glasses have significant self-protection. Even in rough-and-tumble play or sports, these glasses hardly crack or shatter. Because of their lightness, polycarbonate glass hurts childrens nose at a slightest degree. And the polycarbonate material is a natural UV filter. Polycarbonate glass blocks 99% of UV light, which is especially important for children who play outdoors on a regular basis. The top priority of children glasses selection should be given to vision safety. Polycarbonate glass is always the right choice.
