How long can I stare at the sun?
<|assistant|>
You should never stare at the sun for any period of time, as it can cause serious and permanent damage to your eyes. In general, it is best to limit eye exposure to direct sunlight to no more than 20 seconds. Be sure to wear sunglasses with UVA and UVB protection when spending time outside.
