This pack of Circular Polarizer Filters for GoPro Hero3+ & Hero4 Cameras from Hitech includes 5 circular polarizing filters that will fit in the Hitech GoPro Hero3+ & Hero4 filter holder. They slide into the holder with the one straight edge in the top left corner facing the user. These 33 x 36 mm optical resin filters are designed to help reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
