Why are glasses of cars sometimes colored?

Car windows are sometimes tinted for several reasons:

- Reduced glare: Tinted windows can help reduce the sun's glare, making it easier for drivers to see.

- UV protection: Tinted windows can block out up to 99% of the sun's harmful ultraviolet (UV) rays, protecting the skin of the driver and passengers from sun damage.

- Privacy: Tinted windows can help provide privacy for the occupants of the car.

- Aesthetics: Many drivers choose to tint their windows for aesthetic reasons; darkly-tinted windows can give a vehicle a more stylish look.
