Anyone Else Have This Issue??

Here's regular auto film I happened to notice this morning.

I will definitely try that, thanks!

 

I thought it was weird. Have been using these films for 3 years, never had this complain until now. 

 

I had this same issue once using 5% automotive film on a basic entry door for an apartment.  

The oil slick look never actually went away and was more noticeable at different sunlight angles.

I’ve been told it’s more noticeable with flourecent lighting and it looks like you’re right under it.. film is still good/usable right?

It's the SR coating, it is especially noticeable when fluorescent lighting is hitting it. If they swap it out to a LED bulb, it should disappear

Yes nothing wrong with the film at all.

Thin film interference, Google it for thorough read and understanding.

 

In this case the scratch coat is the thin film causes the surface to rainbow. Thin film  blocks and separates colors in visible light; what gets through is what we see as reds, greens, blue and or purple splotches. Florescent lighting is the worst, LED the better to reduce the obvious. I'm unsure whether it is warm or day light LED that reduces the most.

Not sure if I know more or less about it after googling it....

FLUORESCENT LIGHTING IRIDESCENCE ON WINDOW FILMS
The iridescent phenomenon on window films under fluorescent lightings is commonly observed on window films with treated surfaces, for purposes including, but not limited to scratch protection, anti-reflection, anti-bacteria and/or visible light reduction etc. Varying, but less consistent, degree of iridescence can also be observed in non-fluorescent lightings.

Observation & Cause
Light rays appear to be bent (refracted) on the window film surface, creating a colorful rainbow or oil-slick appearance on thin films. T8 Lamps, Fluorescent tubes/lamp generates the strongest effect. The wavelength of these light sources either darkens (distorting the light rays) or brightens (overlapping the distorted light rays) the surface of the window films.

 

Common Reference Names:
• Iridescent Effect
• Rainbow Effect
• Thin Film Interference

Please refer to enclosed reading materials for detailed explanation (Scientific Reference: Thin Film Interference)




Primary Factors Affecting The Level Of Light Reflection/Refraction

• Portion of Installed Film
Like an oil-slick, some portion of the film can exhibit a stronger or weaker iridescent effect; it is possible to observe significant difference of the iridescence if “back-to-back” tints are not used by window panes of the same facing.

• Viewing Angle of User
Incident light is distorted at varying degrees when viewed from different angles; users will usually observe changing level of iridescence as they walk from the left to right of the tinted glass.

• Distance from Light Source
The positions, locations and quantity of the lightings affect the angle of incident light entering the film, which determines the reflection and refraction of light rays visible to the human eye; Iridescent on first glass panel can be different from the last on the same stretch of wall.

Glass patio doors are usually tempered and likely causing that rainbow/oil slick effect
