Unhealthy diet, late night celebrations and inadequate sleep are the causes of puffy eyes. Though puffy eyes subdue naturally within a few hours, but if it's a morning or noon wedding then it will be a problem. A simple remedy is to use frozen teaspoons on the lids. Put two teaspoons in the freezer for around half an hour. Place them on your eyes in such a way that the concave part touches the eyes. Repeat it a few times until the puffiness recedes. Else, you can also put icepacks, frozen cucumber slices or cold teabags on your eyes to get rid of the problem.
