Concept: A Polaroid transmits only the component of light vibrating in one plane.

1. For unpolarised light, the transmitted intensity is half the incident intensity ($I=\frac{I_0}{2}$), so Polaroid filters cut glare and reduce light intensity.
2. Polaroids are used in camera filters and sunglasses to remove reflected glare; they do not change resolution or focusing.
