How To Tell If Persol Sunglasses Are Glass Or Plastic

When it comes to sunglasses, Persol is a brand that stands out for its timeless style and exceptional craftsmanship. However, with the abundance of sunglasses available in the market, it can be challenging to determine whether a pair of Persol sunglasses is made of glass or plastic. In this article, we will explore several foolproof methods to help you identify if your Persol sunglasses are constructed with glass or plastic lenses. So, let's dive in and unravel the mystery!

1. The Weight Test: Feel the Difference
Holding a pair of Persol sunglasses in your hands, you can quickly notice a significant difference in weight between glass and plastic lenses. Glass lenses tend to be heavier, providing a solid and substantial feel, while plastic lenses are typically lighter and more flexible.

2. Visual Clarity: Observe the Lens Surface
Examining the surface of the lenses can offer valuable insights into their material composition. Glass lenses tend to have a higher level of clarity, presenting a crisp and distortion-free view. On the other hand, plastic lenses may show slight imperfections or distortions when viewed at certain angles.

3. Tap Test: Listen for the Sound
Give the lenses a gentle tap with your fingernail or a small object. Glass lenses produce a distinctive high-pitched sound, similar to tapping on a crystal glass. Plastic lenses, on the other hand, create a duller and lower-pitched sound.

4. Temperature Test: Sensitivity to Heat
Glass lenses have a higher thermal conductivity than plastic lenses, meaning they will quickly adjust to changes in temperature. To perform this test, hold your Persol sunglasses under warm water for a few seconds, and then touch the lenses. If they feel warm to the touch, it is likely that you have glass lenses. Plastic lenses, however, will take longer to heat up and may not feel as warm.

5. Magnification Test: Check for Distortion
Using a magnifying glass, carefully examine the lenses for any signs of distortion. Glass lenses typically have minimal distortion and maintain a clear image when magnified. Plastic lenses, on the other hand, may exhibit slight distortions or blurriness at higher magnifications.

6. Polarization Test: Observe the Reflection
Persol sunglasses are known for their excellent polarized lenses, which help reduce glare and improve visual clarity. To check if your lenses are polarized, hold your sunglasses in front of a reflective surface, such as a glass window or a car windshield. Rotate the sunglasses while observing the reflection. If the reflection changes or disappears at certain angles, it indicates that your lenses are polarized.

7. Scratch Test: Assess Scratch Resistance
While both glass and plastic lenses can be scratch-resistant, glass lenses tend to be more durable in this regard. Take a small, sharp object (like a key) and gently try to scratch an inconspicuous area of the lens. If no visible scratches appear, it is more likely that you have glass lenses. However, exercise caution to avoid damaging your sunglasses.

8. Flexibility Test: Assess Lens Flexibility
Flexibility can also provide clues about the material used in the lenses. Plastic lenses are generally more flexible and can bend slightly without breaking. Glass lenses, on the other hand, are stiffer and less likely to bend or flex.

9. Water Test: Observe Water Behavior
Another way to differentiate between glass and plastic lenses is by observing how water behaves on the surface. Glass lenses tend to repel water and cause it to bead up and slide off easily. Plastic lenses, on the other hand, may allow water to spread and create a thin film.

10. Manufacturer's Information: Check for Clues
Sometimes, the manufacturer's information can provide valuable insights into the lens material. Look for any markings or labels on your Persol sunglasses that indicate whether the lenses are made of glass or plastic. Keep in mind that this information may not always be present or easily identifiable.

Determining whether your Persol sunglasses have glass or plastic lenses is essential for understanding their durability, optical quality, and overall performance. By using a combination of tests like the weight test, visual clarity examination, tap test, temperature test, magnification test, polarization test, scratch test, flexibility test, water test, and checking for manufacturer's information, you can confidently identify the material composition of your Persol sunglasses. Remember, these methods are not foolproof, so if you are still unsure, it is best to consult with a professional or the manufacturer directly. Enjoy your stylish Persol sunglasses and protect your eyes with confidence!
