If it's a linear polarizer, you will see your eye reflected back to you in the mirror regardless of which side is facing you. If it's a circular polarizer, your eye will only appear on the naturally facing side—the opposite side will appear black.

What is linear polarizer?
Linear Polarizers are Polarizers designed to linearly polarize incoming light. Passing white light through a Linear Polarizer blocks half of the incident light, causing the electric field component to displace so that it oscillates in only one plane with respect to the direction of propagation.
When should you not use a circular polarizer?
Among the most important is that polarizers work best when at a 90° angle from the sun. This means that you should practically never use a polarizer facing directly toward the sun. Another reason to take off the filter for shots that include the sun is that the extra glass can result in more flaring.
What is a circular polarizer?
A circular polarizer is designed to do one thing: remove or control reflections from surfaces like water, glass, paint, leaves, sky, buildings, streets, and the list goes on. When light hits those surfaces they create glare that increases highlights, reduces color and detail.
Are circular polarizers necessary?
Low light situations won't benefit from a polarizer because you'll need all the light you can get for fast shooting. If you want reflections, like in a lake scene, use a circular polarizer so that you can take a shot WITH the polarizer engaged and another shot WITHOUT the polarizer engaged.
What is the use of polarizer in LCD?
Polarizing film is one of the core elements of LCD technology that enables displaying of images on LCD screens. Starem® POL (Polarizing Film) convert unpolarized light into linearly polarized light by transmitting only the incident beam that propagates in one direction and absorbing all others.
Does circular polarizer reduce light?
What does a circular polarizer do? A polarizer reduces reflected light before it enters your lens. ... This is useful for shooting reflective surfaces such as water, glass, wet rocks, and cars. Most of the time, you want to control those reflective surfaces and reduce the glare of reflected light.
How many stops is a circular polarizer?
Yet "standard" circular polarizing filters cut light transmission by 1.5-2.5 stops.
Should I use a polarizing filter for sunsets?
Use of a polarization filter for sunsets is also not necessary. It won't do any harm, so leaving the filter on you lens is possible. But be aware of bright sunlight. It can produce extra flares because of the extra glass in front of your lens.
How do you use a circular polarizer for portraits?
Polarizers works most effectively when you are shooting at a 90 degree angle (or perpendicular) from the light source (usually the sun). So when positioning your portrait subject, if you point your index finger at the sun, then you should be shooting in the direction your thumb is pointing.
How does a circular polarizer work?
Circular Polarizing Filters attach to the thread of your lens and reduce reflections emitting off the subjects you're photographing. The effect this can give is, darker deeper sky color and ability to see through windows and water that otherwise portray only surface reflections.
