Understanding
POLARIZED SUNGLASSES
Polarized lenses are designed to reduce glare from reflective surfaces such as water, snow, and pavement. The lenses contain a special filter that blocks horizontal light waves, which are the primary cause of glare. This results in clearer vision, better contrast, and reduced eye strain. Polarized lenses are particularly useful for outdoor activities such as fishing, boating, and skiing, where glare can be a significant problem.
