The high blood pressure would last for a while after you stop using, but I think it would have to be consistantly high and/or very high in order to cause any vision disruptions. Have you smoked a lot/often/for a long time?
Also, does it feel as though you have something in your eyes? If so Ive felt this for the past few days and I think its primarily the smokey air. It helped signifigantly to open the doors/windows and really air out my apartment as much as possible along with some moisturizing eyedrops to keep them from getting dried out
