A polarized lens is a kind of vertical filter that blocks the sunlight that reaches the eyes horizontally, such as that reflected in the sea, snow, road and asphalt, and allows the passage of vertical light that can be used to see clearly.
They can be combined with UV and visible light filters so that they provide complete protection.
They provide glare-free vision. At least the horizontal light ones are the most frequent.
Greater sharpness and better contrast.
Perception of more natural colors.
Highly recommended for people with high sensitivity to light or photophobia.
