There is a common misconception that you shouldn't look into a microwave while it's running.
This can allegedly lead to vision problems, including cataracts and blindness.
However, experts say this is nothing more than a myth.
Is it okay to look into a working microwave?
Yes, it does not cause vision problems. The radiation that can harm the eyes remains inside the microwave oven, it is reliably shielded by the body and the grid.
To actually damage your eyesight, you would have to force the microwave oven to operate with the door open, and this is a design limitation by manufacturers.
Looking at a smartphone screen is potentially more dangerous than looking at a working microwave.
Not because the smartphone emits any harmful radiation, but because looking at one point for a long time is harmful to the eyes.
