Nowadays, UV resistant glasses are usually divided into two categories: sunglasses and polarizers. Sunglasses are commonly known as colored glasses used to block sunlight and ultraviolet rays. In people's daily lives, in addition to sunlight and ultraviolet rays, irregular diffuse reflection light occurs when light passes through uneven roads, water, and other places, commonly known as "glare". The presentation of glare can cause discomfort and fatigue in the eyes, and affect the clarity of vision. Polarizing lenses are sunglasses that can effectively filter out glare.
It is understood that a small portion of customers who purchase polarizers are those who need to ride bicycles. There are many types of polarizers on the market, with dark gray and vermilion as the main colors. Generally, brands also have fashionable bright colors such as white and bright yellow.
1. "There are many ways to distinguish between polarizing lenses, and a simpler one is to stack two polarizing lenses vertically, resulting in a non transparent image. The reason is that polarizing lenses are specially designed to only allow flat light to pass through the lens, and when the two lenses are stacked vertically, most of the light lines are obstructed. When purchasing, simply follow these simple steps to immediately determine the authenticity and quality of the product."
2. At the same time, ordinary people will have a discrimination board with a polarizing mirror, which can show black stripes to the naked eye, but with a polarizing mirror, you can see the expected black stripes and white stripes to the naked eye! Sunglasses can see it!
