Visual Acuity
(Important when looking at a window film sample on a window)

The human eye has a logarithmic response to light, which means that small changes in light levels at low light levels are more noticeable than at higher light levels. This phenomenon is known as the Weber-Fechner law.

So, when a window film with a 30% VLT rating is applied, it blocks 70% of the light from passing through. However, the reduction in perceived brightness by the human eye might not be as significant as the percentage of light blocked. Due to the logarithmic response of the eye, the perceived reduction in brightness might be closer to 7% or even less.

This means that even though the VLT rating suggests a substantial reduction in light transmission, the actual impact on the perceived brightness might be relatively minor. It's an important consideration when evaluating the visual effects of window films.


Solar control window films are an excellent investment for any commercial building. They offer numerous benefits, including energy savings, increased comfort levels, and protection for your furnishings. By choosing the right film for your needs, you'll be able to enjoy all of these benefits and more.
