Shop Talk
O.O
Me: "Okay, lets take a look at it."
C: She pulls it out of her purse. "It has something brown on it, see, and it's on the inside too!" she says while opening and handing me the phone.
Me: ๐คจ "Where's the..."
C: "And look! It moves too!!"
Me: ๐ณ "Where is it at?" ๐
C: She takes off her sunglasses and says, "It's right... oh, where'd it go? Wait, was it from my sunglasses? Did I drive all the way up here and it was just my sunglasses?"
Me: "Are those polarized lenses by chance?"
C: "****. Don't go home and tell your wives how stupid I am."
Okay, I'll just tell the people on phonescoop...
The lady said "The screen on my phone is all jacked up." (her words).
Before I even looked at the phone I asked if the sunglasses she was wearing were polarized.
She took them off, looked at the phone again simply said "Crap, I'm such a retard." and left.
Fortunately, I managed to stifle the laughter until she got out the door.
It's not just phones it's just about anything plastic, or even the tint on car windows.
You'll see spots or lines across the screen.
Only thing I ever bothered with polarized glasses for before was back when I was thinking about majoring in aquaculture and wanted to watch the little fishes.
I can't find any that work well enough that I still don't squint, but polarized lenses are about as good as I can get (without spending hundreds of dollars anyway).
Most phone screens are a type of LCD (Liquid crystal display). The LCD works with an electrical current to "flip" or "align" the crystals in a way that will cause the LCD to be opaque in areas. The LCD does this in a way to make numbers/letters/icons. When you put on polarized lenses (sunglasses usually), the polarization blocks light of a certain wavelength. What you are seeing in the LCD is light "bands" at the edge of the wavelength that is filtered or blocked by your sunglasses. You'll also experience this with Laptop screens, polarized auto glass, etc.
