I don't have anything to add as to the harmfullness of light leaks, but the amount of light getting in increases with time; tents deteriorate, it's unavoidable. When new my tent had zero pinholes, now it is full of them from the fabric stretching around the stitching.talking about what kind of tent to buy and to be careful to choose a tent that isn't notorious for light leaks.
I just want to suggest to those who are worried about light leaks to get a piece of fabric long enough to wrap around the tent, then pin it into a box at the top. The fabric doesn't have to be thick/insulating or even light proof. It just needs to diffuse the light and prevent high intensity spots coming through the pinholes. Plus now you can have a tent with a picture/pattern if it's in a living area.
