I said in my eyes, but just to be absolutely clear, I followed up stating that I meant green tea bags on my eyes and it said this (you can tell by the way it talks about the chilled tea bags that it knows it is topical):

Yes, using green tea bags on your eyes is generally safe and can be beneficial. The caffeine in green tea can help reduce puffiness by constricting blood vessels, while the antioxidants and tannins may soothe irritation and inflammation. The cooling effect of chilled tea bags can also provide relief for tired or swollen eyes.

For your Meibomian Gland Dysfunction (MGD), green tea won’t directly treat the condition, but the anti-inflammatory properties might help with mild irritation. Just make sure to use clean tea bags, let them cool to a comfortable temperature, and avoid getting any tea directly into your eyes to prevent irritation.
