## Questions & Answers

**Q: How quickly do the lenses change tint?**
A: The transition is gradual, not instant. Darkening and fading times vary with UV exposure and temperature. Allow time for the lenses to adjust when moving between different environments.

**Q: Will the lenses darken inside a car?**
A: Darkening may be limited because windshields filter much of the UV light that activates the lenses. The tint inside a car may remain lighter than it does outdoors in direct sunlight.

**Q: What activities are these sunglasses suitable for?**
A: They are designed for everyday outdoor wear, including walking, cycling, hiking, running, golfing, and fishing. Tint adapts to UV exposure, but may not change noticeably during brief shifts between sun and shade.

**Q: Can I adjust the fit?**
A: Yes. The adjustable frame, temple arms, and nose pads let you fine-tune the fit, while spring hinges provide flexibility at the temples. Adjust gently, follow the adjustment guide, and compare the listed dimensions with your current glasses.

**Q: What comes in the package and what support is included?**
A: You will receive the glasses, a carton box, a zipper case, a cleaning cloth, instructions, a polarization test card, spare nose pads, and a screwdriver.ROCKNIGHT offers 30-day free returns and exchanges plus a 1-year product coverage.
