Common Problem-What is a polarizer?Polarizers are manufactured based on the principle of polarization of light, such as the principle of blinds. The light is adjusted to the same direction of light entering the eye, effectively holding and filtering the scattered light in the beam, so that the scene looks soft and not dazzling.
-The problem of wearing polarized sunglasses to see the electronic screen:At present, electronic screens (computers, mobile phones, etc.) on the market are covered with polarizing films to weaken the strong light of the light source.When wearing polarized sunglasses, the polarizing film of the electronic screen and the polarizing film of sunglasses will appear heavy. When the heavy angle is at the intersection of 90 degrees, the tortoise may have a black screen or the green condition of the screen is unclear. This phenomenon is normal; please wear polarized sunglasses according to different usage scenarios.
-How to identify polarizer:Point the glasses horizontally at the LCD screen, then rotate the lens clockwise 90 ° to darken the color, and then turn it back to normal, this is the polarizer.
-Precautions for wearing:1) Use both hands to hold the temples and take off the glasses along the parallel sides of the cheeks2) When placing glasses, place the lens with the concave side up to reduce mirror wear.
Daily cleaning and maintenance:1) When not using glasses, please wrap them with lens cloth, place them in the glasses case, and store in a dry environment with a temperature between -10 ℃ and 35 ℃;2) Sunglasses can be cleaned with clean water or special glasses cleaning liquid. Do not use any liquid or alcohol with dissolving power. Avoid using unclean or abrasive cloths to clean and scrub, so as not to change the filter effect of the lens;3) Avoid long-term storage in a high-temperature environment (above 50 ° C), such as on the dashboard of a car.
