Like I said your eyes wont see the difference but your plants will. You probably should study up a bit more on glass and PAR light.Not sure as it really makes too much of a difference, as it's something I've always used and seems to not create any issues. It's just clear plastic, so I can't see how it's diffusing too much
Heres a link back to the basics:
