Why do your eyes burn when you open the oven while baking bread?

Answer 1

When the oven door is first opened during baking, hot air wafts out. This air is hot enough to quickly evaporate some of the moisture off the surface of the eyes, making them feel dry (and uncomfortable). The nerves for the surface of the eyes are very sensitive, because the eye is fragile, so they are also detecting the heat from the air as well as the dryness of the eye.

Answer 2

When you open the oven while baking bread, the heat causes the release of volatile compounds like aldehydes and organic acids from the dough. These compounds can irritate the eyes and respiratory system, leading to a burning sensation. Additionally, the heat can also cause moisture in the eyes to evaporate quickly, further contributing to the discomfort. It is important to allow the oven to vent properly before opening it to minimize exposure to these irritants.
