What are polycarbonate lenses?

Picture this: you sit down in the car after a long day, and hear a crack. You look down to see that your new sunglasses are broken after you mistakenly sat on top of them. Frustrating right? You're not alone. The worldwide clumsiness epidemic is leading some people to consider polycarbonate lenses for durable daily-wear.

Polycarbonate is a thermoplastic material formed from tiny solid pellets. These pellets are melted and molded under high pressure into sunglasses, whether they are the lenses or the frames themselves. Polycarbonate, produced from bisphenol A and phosgene, is extremely tough. Its strength surpasses glass by 25,000% and traditional plastics by 3,000%. Polycarbonate plastics are used in a wide array of applications, including durable fencing and bullet-resistant windows.

Method Seven designs and manufactures grow room sunglasses with both polycarbonate and glass lens options. The earth's atmosphere filters out a considerable amount of ultraviolet (UV) light; however, it can’t shield you from the harmful effects of grow room lights. Wearing specialized grow room sunglasses helps protect your eyes from ceramic metal halide (CMH) bulbs, which emit harmful UV, and high-pressure sodium (HPS) lamps, which emit infrared heat and distort the color spectrum. Method Seven's entire product line of glass and polycarbonate sunglasses offers complete protection from UV and infrared. Notch filtering technology tailored to each grow room light spectrum allows for perfect color-correction.

So, if all these qualities are provided in both glass and polycarbonate sunglasses, which one is right for you? Glass lenses are considered top-of-the-line, plus they are scratch-resistant and easier to clean (especially when coated with sticky resin.) However, if you have a tendency for dropping or breaking your sunglasses, then polycarbonate may be your new best friend.

Whether you choose glass or polycarbonate for your grow room sunglasses, make sure to choose a product that will protect your eyes from UV and infrared, as well as offer color correction for your grow room light spectrum.
