It's so embarrassing that my prescription glasses often fog up especially in winter. Is there anyone who can tell me some good methods to stop my glasses from fogging?

The reason of glasses fogging up is due to the temperature change immediately. If you want to release this problem, you should find a way to reduce the temperature difference. For example, you can preheating or wipe your glasses before you go into another environment. Besides, you also can choose anti-fog lenses to make it better. However, even the best anti-fog lenses do not 100% avoid fog. This is a big problem need to figure out in glasses industry.
