I found that
PureVision was not as good as the Soflens for starbursts initially. But I continued wearing them and they are better. I have now been wearing my purevision 24/7 (sleeping in them) and find I need to put eye drops in when I wake up, but apart from that, they are great. I too, had problems with stinging eyes - but now I just simply don't take them out as often!
I NEVER go past the prescribed wear times ie 2 weeks for 24/7 or 1 month for daily use. Although my friend does - I just won't risk it.
