The intensity of the color change in these lenses depends on both the temperature and ultraviolet (UV) light exposure. Here s what you need to know:

• Temperature Matters: The higher the temperature, the less intense the color change will be.

• Seasonal Changes: Because of the temperature factor, you ll notice that the lenses change to a darker color in winter and are lighter in summer.

• Optimal Performance: These lenses perform best and show the most vibrant color changes at temperatures between 23-28°C (73-82°F).

• Quick Test: If you expose these lenses to boiling water, they will instantly turn colorless. This experiment demonstrates that high temperatures cause the lenses to lose their color.

  Outdoor Use in Summer: During summer, the high outdoor temperatures and UV radiation cause the lens to both change and fade in color simultaneously.

  Caution: Avoid leaving your glasses in the car during summer, as the high heat can affect the color-changing feature.
