Window tinting or sunscreening for passenger and multipurpose vehicles (MPVs) provides sun protection and shielding due to medical conditions and legal issues.

The Visible Light Transmission explains the level of tinting the car windows can have. We understand this as the percentage of light that a tint film permits to pass through your car windows.

A higher VLT means more light will pass through the window, while a lower VLT means a lesser amount of light will do so.
