A 70% tint allows a significant amount of light to pass through the window. It provides a subtle shading effect, barely darkening the glass. Objects and individuals inside the vehicle or building are still clearly visible. Think of it as a very light filter, softening the intensity of sunlight rather than creating a dark or private space.
The application of such a light tint offers several advantages. It can reduce glare, contributing to improved visibility and reduced eye strain. While it does not offer significant privacy, it can help to mitigate UV ray exposure, protecting interior surfaces from fading and potentially reducing heat buildup. Historically, lighter tints have been favored in regions where darker tints are restricted by law, offering a legal alternative for glare reduction.
