Phillip Mosness Posted November 17, 2015 Share Posted November 17, 2015 just curious why the reflections in eye glasses often have a green hue. I might guess it has to do with florescent lighting having a spike in the green of the spectrum, but only in people's glasses? I see it in both video and film.

Premium Member Satsuki Murashige Posted November 17, 2015 Premium Member Share Posted November 17, 2015 The simple answer is the lens coatings on the glasses. Coatings are microscopic layers of chemicals applied to the glass surface designed to reflect away or absorb different wavelengths of light in order to produce clearer images to the viewer. If you're seeing green reflected back, then that means this light is being rejected by the coatings and not passed through to the eye. Fluorescent lights generally do contain a green spike so you would expect them to appear less green when viewed through these multi-coated optics. Not sure if it works that way in practice though.

Premium Member David Mullen ASC Posted November 17, 2015 Premium Member Share Posted November 17, 2015 It's the anti-reflection coatings -- even a normal white tungsten light becomes a green reflection. Link to comment Share on other sites More sharing options...
