The sunglass near me also has an important indicator of light transmittance, which is the ratio of the luminous flux passing through the lens to the incident luminous flux and is also an important performance indicator specified by mandatory standards. If light-colored sunglasses are used for shading, the wearer will not be able to achieve the effect of shading. Using sunshades as light-colored sunglasses can affect the clarity of the wearer's vision.

 

Place sunglasses in front of your eyes and observe distant targets, such as window frames or door frames, through the lenses. Then move the glasses up, down, back, and forth, ensuring that the target does not swing or deform in a wavy manner. You can also observe the image of the lamp tube on the surface of the sunglasses lens under a fluorescent lamp, and rotate the sunglasses to make the lamp tube image appear in different parts of the lens. The lamp tube image is best without deformation.

 

The color of the lens should not be biased, and the color of the surrounding environment should not be distorted. Before wearing sunglasses, first observe objects of red, green, yellow, and other colors. Then, wear sunglasses and observe the same object. The colors observed twice should not deviate, otherwise, it will reduce the ability to recognize traffic signals. Attention should be paid to the identification of colored dry lenses, especially brightly colored sunglasses.
