Do plastic sunglasses scratch easily? This is a question that many consumers often ask when considering purchasing sunglasses. As a supplier of plastic sunglasses, I have encountered this query numerous times and have delved into the science behind the scratch – resistance of plastic sunglasses. Plastic Sunglasses
Understanding Plastic Sunglasses
Plastic sunglasses are a popular choice among consumers for several reasons. They are lightweight, comfortable to wear for extended periods, and come in a wide variety of styles and colors. The plastics used in sunglasses are typically polycarbonate or acrylic.
Polycarbonate is a high – impact resistant plastic. It is known for its excellent optical clarity and is often used in safety glasses as well as sunglasses. Acrylic, on the other hand, is a more affordable option. It offers good optical properties and can be easily molded into different shapes, which makes it a common choice for fashion sunglasses.
Factors Affecting Scratch Resistance
The scratch resistance of plastic sunglasses is influenced by multiple factors.
1. Quality of the Plastic Material
Higher – quality plastic materials generally have better scratch resistance. For polycarbonate, advanced manufacturing processes can enhance its scratch – resistant properties. Some manufacturers use special coatings on polycarbonate lenses to make them more resistant to scratches. These coatings can create a harder surface that is less likely to be damaged by everyday wear and tear.
Acrylic, while less scratch – resistant than polycarbonate in its natural state, can also be treated with scratch – resistant coatings. However, the effectiveness of these coatings can vary depending on the quality of the coating and the application process.
2. Coating Technology
The scratch – resistant coating is a crucial factor in determining how easily plastic sunglasses scratch. There are different types of coatings available in the market. Some are hard – coatings that form a protective layer on the surface of the lens. These coatings are designed to withstand minor abrasions and scratches.
The durability of the coating depends on its thickness and composition. A thicker and well – formulated coating will provide better scratch protection. However, it’s important to note that even the best coatings can wear off over time, especially with frequent use and improper cleaning.
3. Usage and Handling
How the sunglasses are used and handled has a significant impact on their scratch resistance. If sunglasses are constantly tossed into a bag with keys, coins, or other hard objects, they are more likely to get scratched. Similarly, using rough or dirty cloths to clean the lenses can cause scratches.
On the other hand, if users are careful with their sunglasses, store them in a proper case when not in use, and clean them with a soft, microfiber cloth, the likelihood of scratches can be significantly reduced.
Testing the Scratch Resistance of Plastic Sunglasses
To determine the scratch resistance of plastic sunglasses, various tests can be conducted. One common test is the Taber abrasion test. In this test, a sample of the sunglass lens is rotated against an abrasive wheel under a specific load. The amount of wear and the change in optical clarity are then measured.
Another test is the sandpaper test. A piece of sandpaper is rubbed against the lens surface with a certain pressure and number of strokes. The appearance of scratches on the lens is then evaluated. These tests help manufacturers understand the scratch – resistant capabilities of their products and make improvements if necessary.
Comparing Plastic Sunglasses with Other Materials
When compared to glass sunglasses, plastic sunglasses are generally more prone to scratching. Glass is a harder material, and in its natural state, it is more scratch – resistant than plastic. However, glass sunglasses are heavier and more fragile, which can be a drawback for some users.
Metal – framed sunglasses also have their own characteristics. While the frames are usually quite durable, the lenses, which are often made of plastic, are still subject to scratching.
Maintaining the Scratch Resistance of Plastic Sunglasses
To keep plastic sunglasses in good condition and minimize scratching, here are some tips:
- Proper Storage: Always store sunglasses in a protective case. This will prevent them from coming into contact with hard objects that could scratch the lenses.
- Cleaning: Use a soft, microfiber cloth to clean the lenses. Avoid using paper towels or tissues, as they can contain small particles that may scratch the surface. If the lenses are dirty, use a mild soap and water solution. Rinse the lenses thoroughly and dry them with a microfiber cloth.
- Avoid Rough Surfaces: Do not place sunglasses on rough surfaces, such as concrete or sand. Even a brief contact with these surfaces can cause scratches.
