How To Tell If Oliver Peoples Sunglasses Are Glass Or Plastic

When it comes to investing in a pair of sunglasses, it's important to know what you're getting. Oliver Peoples is a renowned brand known for their high-quality eyewear, but how can you tell if their sunglasses are made of glass or plastic? In this article, we'll explore some foolproof methods to help you determine the material of your Oliver Peoples sunglasses. So, let's dive in and unravel the mystery!

1. The Weight Test: Feel the Difference

One of the easiest ways to distinguish between glass and plastic sunglasses is by their weight. Glass lenses tend to be heavier than plastic ones. Hold the sunglasses in your hand and compare the weight to other sunglasses you own. If they feel significantly heavier, there's a good chance they are made of glass.

2. The Tap Test: Listen for Clarity

Another method to determine the material of your sunglasses is the tap test. Tap the lens gently with your fingernail and listen for the sound it makes. Glass lenses produce a clear, high-pitched sound, while plastic lenses create a duller, lower-pitched sound. This simple test can give you a quick clue about the material.

3. The Scratch Test: Assess Durability

While this method requires caution, it can be effective in distinguishing between glass and plastic lenses. Use a small, inconspicuous area of the lens to lightly scratch with a metal object, such as a key. Glass lenses are more scratch-resistant than plastic lenses, so if you notice minimal or no scratches, it's likely that your sunglasses have glass lenses.

4. The Polarization Test: Observe Light Reflection

Polarized lenses are a popular feature in sunglasses, as they reduce glare and enhance visual clarity. To determine if your Oliver Peoples sunglasses have polarized lenses, hold them up to a reflective surface, such as a glass window or a shiny car surface. Rotate the sunglasses while observing the reflection. If the intensity of the reflected light changes or reduces significantly at certain angles, it indicates the presence of polarized lenses, which are often made of glass.

5. The Temperature Test: Feel the Chill

Glass and plastic have different thermal properties, and this can be used to your advantage. Place your sunglasses in the refrigerator for a few minutes to cool them down. When you touch the lenses, glass lenses will feel colder than plastic lenses due to their higher thermal conductivity. Keep in mind that this test may not be foolproof, as the ambient temperature can also affect the initial temperature of the sunglasses.

6. The Visual Clarity Test: Observe Distortion

One characteristic of glass lenses is their superior optical quality, which results in minimal distortion. Plastic lenses, on the other hand, may exhibit slight distortion or warping. Put on your Oliver Peoples sunglasses and look at objects with straight lines, such as door frames or window blinds. If you notice any distortion or bending, it suggests that your sunglasses have plastic lenses.

7. The Reflection Test: Examine Reflections

Reflections can provide valuable insights into the material of your sunglasses. Hold your sunglasses at an angle and observe the reflections on the lens surface. Glass lenses tend to produce sharper and more distinct reflections, while plastic lenses may create softer and slightly blurred reflections. This test can help you differentiate between the two materials.

8. The Float Test: Check Buoyancy

This test works best if you have a spare pair of sunglasses with known glass or plastic lenses. Fill a bowl or sink with water and gently place your sunglasses on the surface. Glass lenses are denser than water, so they will sink, while plastic lenses will float. Comparing the buoyancy of your Oliver Peoples sunglasses with a known pair can give you a clue about their material.

9. The Flexibility Test: Assess Resistance

Flexibility can also indicate the material of your sunglasses. Plastic lenses tend to be more flexible and can bend slightly without breaking. On the other hand, glass lenses are rigid and less prone to bending. Be cautious while performing this test, as excessive force can damage your sunglasses.

10. The Manufacturer's Information: Read the Details

If you're still unsure about the material of your Oliver Peoples sunglasses, refer to the manufacturer's information. Most reputable brands provide details about the lens material in the product description or packaging. Check for terms like "glass lenses" or "plastic lenses" to confirm the material.


Determining whether your Oliver Peoples sunglasses are made of glass or plastic doesn't have to be a mystery. By using a combination of these tests, including weight, sound, scratch resistance, polarization, temperature, visual clarity, reflections, buoyancy, flexibility, and manufacturer's information, you can confidently identify the material of your sunglasses. Remember, investing in high-quality eyewear is essential for protecting your eyes, so knowing what you're getting is crucial. Enjoy your stylish and functional Oliver Peoples sunglasses, knowing exactly what they're made of!
