What Type Of Plastic Are Sunglasses Made From

Sunglasses have become an integral part of our fashion accessories. Be it for style or for protection from harmful UV rays, sunglasses are always in vogue. But have you ever wondered what type of plastic sunglasses are made from? Let's find out.
There are different types of plastic used to make sunglasses. Some of the common types are as follows:
1. Acetate: This is a thermoplastic material that is derived from wood pulp. It is commonly used in high-end sunglasses as it is lightweight, flexible and has a wide range of color options. It is also hypoallergenic and can be easily molded into different shapes.
2. Polycarbonate: This is a type of thermoplastic material that is known for its durability and impact resistance. It can withstand strong impacts and is often used in sports sunglasses. Polycarbonate lenses are also thinner and lighter compared to other plastic lenses, which make them more comfortable to wear.
3. CR-39: This plastic material is often used in mid-range sunglasses. It is affordable, lightweight, and has good optical properties. However, it is not as impact resistant as polycarbonate and may not be suitable for sports activities.
4. Nylon: This is a lightweight and flexible material that is commonly used in sport and wraparound sunglasses. Nylon frames are also durable and can withstand high impact.
Apart from the above-mentioned plastics, there are other materials such as TR90, Ultem, and propionate that are used in sunglasses.
It is important to note that the type of plastic used in sunglasses also affects its quality and price. Higher-end brands use better quality materials, which make their sunglasses more durable, comfortable, and offer better visual clarity.
In conclusion, sunglasses are made from various types of plastic materials, and each material has its own set of benefits and limitations. It is important to choose sunglasses that suit your needs and preferences. Always make sure that the glasses you buy have proper UV protection to keep your eyes safe from harmful rays. So, next time you buy a pair of sunglasses, make sure you know what type of plastic they are made of.
