Is real life full of shades of lamps?
If you think about it, most lamps have lamp shades on them. There are many lamps throughout the world, probably multiple lamps within your home. And pretty much all of these lamps have lamp shades on them. Even the ceiling fan lamps have shades on them although they look different from table lamp shades
My point is that naked lightbulbs, sans shades, are unattractive and the brightness is harsh on the eyes. So life is full of shades of lamps. It's something that you take for granted, but shouldn't. You might wake up tomorrow and all lamp shades could have totally vanished
