UV Glass Question

[theantiquetiger]

Will a photograph framed under UV Protectant glass still fade from just light (bleach out) or is it just the UV rays that fade pictures?

I was told that the UV frame should protect it from fading with light but never allow a picture (especially an older one) to be exposed to direct sun light. Also, I seem to think there is another issue with an older picture having to do with the chemicals used and acidity levels that could cause problems over time. If it is something of value, it might be worth paying the money to have the photo framed by someone who specializes in it.
