Excuse me, are tens of dollars of polarized glasses useful to netizens? thank you

As long as you buy glasses in a regular store, you will definitely get 1 point and 1 point.

I have used four pairs of polarized sunglasses for several years, and the prices are 128, 280, 350 and 28-350 respectively. I left it at home and bought it temporarily for 28 yuan from a stall.

Dozens of dollars will have the same polarization effect. He has a photo to show you. Fish invisible to the naked eye can be seen with glasses. But the effect is definitely not as good as several hundred yuan. The most obvious thing is that hundreds of three pairs of smart phones and car windshields have obvious rainbow effects, but I can hardly see the one in 28 yuan.

But it doesn't mean that the higher the price of polarized sunglasses, the better the cost performance. One is that other friends say there is brand value in it. The second is the frame. If you have worn myopia glasses, you will know that metal frames are expensive, but brand polarized sunglasses are all metal frames. . .

Having said so much nonsense, I'll give you some personal advice: the price of a polarizer for tens of dollars can be reduced to 20 or 30, and you can wear it occasionally. If you wear it for a long time and can afford it, buying a polarizer of 2 or 300 in a regular store can better protect your eyes. Occasionally, it is ok to spend tens of dollars on fitness tours, otherwise it would be a pity to lose or damage them.

No matter what price you buy polarized sunglasses, the most important thing is the shape of the frame and the shape of the lens! Wearing it can make your eyes comfortable, but it can't make people look like blind people, fortune tellers or even triads.
