Problem, how?
If your eyes benefit by the sight picture, the colors, the brightness, then by all means consider them. With my aging eyes, I find having a little "boost" out there helps much more than it used to. Fiber optic sights, larger (ie, "big dot") sights, tritium/night sights ... they all have some benefits, at least for my eyes. If you find such improvements, then it should be a good thing for you.
Of course, if actually used at night, the muzzle flash will wash out most (if not all) of whatever visibility of those little dots you'd otherwise have. But it can help that first shot or two be more accurate. Some don't think much of night sights. I think they can be useful, if your eyes would benefit. Crucial? No, but useful for many. JMHO.
