Polarizing sunglasses are great at reducing glare from reflective surfaces like water, snow, and roads, making them ideal for driving, boating, fishing, and skiing. They enhance visual clarity and contrast, improve comfort, reduce eye strain, and increase safety in bright conditions.
However, pilots are generally advised against wearing them as polarized lenses can interfere with reading cockpit displays, affect visibility of other aircraft, atmospheric conditions, and runway details, and create distortions in the windscreen, all crucial for safe navigation.
