Wear a mask to prevent fogging
Two steps to help you
1. Fold the top (that is the metal wire side) inwards in one direction before wearing a mask, with a width of about 2 cm.
2. Put on and press the metal wire on the bridge of your nose as usual to keep the mask close to your face.
This method can induce a diversion effect in the mask, so that the exhaled air flows upward through the center of the two lenses, reducing the passage of warm air, and the lenses are naturally less likely to fog.

戴口罩防眼鏡起霧
兩個步驟幫到你🤓
1. 戴口罩前先將頂部（即有金屬線）一方向內對摺，幅度約2厘米。
2. 再如常戴上並按壓鼻樑位置金屬線，讓口罩緊貼面部。
此做法能令口罩內出現導流效果，令呼出的空氣透過2塊鏡片中央的位置向上流走，減少暖空氣通過，鏡片自然較不易起霧。

Coronavirus: How eyes may play a role in its spread
Our eyes might play an important role in the spread and prevention of the coronavirus.
For example, a Peking University physician believes he may have contracted the coronavirus while not wearing eye protection when treating patients. Medical officials, though, say while this is possible, it may be unlikely.
Meanwhile, to cut your risk of contracting coronavirus, avoid touching your eyes, nose or mouth with unwashed hands.
The World Health Organization (WHO) also recommends protective eyewear, among other precautions, if you will be near someone with the virus for an extended period.
The relationship between the Wuhan virus and your eyes is complicated.
It’s thought that the Wuhan virus spreads from person to person mainly through airborne “respiratory droplets” produced when someone coughs or sneezes, much like the flu virus spreads. These droplets can land in the mouths, eyes or noses of people who are nearby, or possibly be inhaled into the lungs.
