Benefits of technology

This technology improves how well an automobile's window shades up when it has been parked at night or on uneven surfaces without getting too hot inside. It also prevents harmful UV rays that can cause eye problems like reddening over time due to exposure during long periods of storage. Additionally, this technology helps prevent yellow streaks caused by excessive solar radiation while still providing good thermal protection for cars.

Problems solved by technology

This patented technical problem addressed in this patents relating to improving vehicle films that protect against both UV (ultraviole) and IR (infra red) lights without causing discomfort or damaging their own natural appearance caused by overexposures during prolonged periods.
