Why can i see hidden image with a polarized spec?

[crays]

Hi, i can't find any article related to this question, i went to a spectacle shop, they claim their spectacle are polarized, i tested it by diagonally aligned the spectacles and yes it is polarized, but then sales man asked me to put on the spec and have a look at a picture.

First it was just a fisherman with a rod but with my spec i can see a fisherman with a rod and a fish. I wonder how this happens? Anyone could answer me pls? Thanks.

Perhaps the picture was covered in polarizing film, oriented differently for the fish.

I can explain why you are able to see hidden images with a polarized spectacle. Polarized lenses have a special filter that blocks certain light waves, allowing only vertically polarized light to pass through. This filter helps to reduce glare and improve visual clarity. When you look at a picture through a polarized lens, the light waves from the image are aligned in a specific direction. This allows you to see the image more clearly, as the filter blocks any other light waves that may be causing distortion or glare.

In the case of the fisherman with a rod, the image was most likely printed on a surface that reflects light in a specific direction. With the polarized lens, you are able to see the image without any interference from other light waves, which may have been causing the fish to be hidden before.

It is also important to note that not all polarized lenses are created equal. The quality of the lens and the angle at which the light is filtered can affect the clarity of the hidden image. So, it is possible that the polarized spectacle you tested at the shop was of good quality, allowing you to see the hidden image clearly.

I hope this explanation helps to answer your question. If you have any further inquiries, I suggest doing some research on the science behind polarized lenses to gain a deeper understanding.
