When you say that you can’t wear mascara or dark eyeliner, I assume it’s because you are not able to apply it or that it irritates your eyes. Instead of wearing eyeliner on the inside of your eyes, how about applying it under your eyelashes from the outer corners to just over half way and then blend it with your finger. For dramatic look or for a night out apply a darker colour and blend a bit further towards the inner corner of your eye. Tip: Make sure the pencil tip is quite soft so you don’t get a sharp line

I guess this depends on just how sensitive your eyes are, but you could maybe try an eyelash tint? I did this when I had laser treatment on my eyes. Not wearing eye make-up for a month was far more traumatic than the treatment itself!

By can't do you mean physically can't? If so then try make-up for sensitive eyes. Or, if you just can't wear dark eye make-up then try a little blue eyeliner and clear mascara- it will look more natural and less dramatic.
