You are probably right about that! Have you been resting well-sleep? It is highly unlikely that the bud caused the vision problem. Not knowing your age, etc. Having vision problems simply is not a side-effect of cannabis. You have allergies? I use cannabis for allergies! However, I do use some OTC stuff for them at times! And it is possible to be allergic to anything! Some are even allergic to the medicine given for allergy probs!

Vision, normally goes 'slowly' over years! Inner ear problems are more likely to cause being dizzy! You may need some OTC meds. Feel pressure in your ears? Even if you don't, it is highly probable! Most likely this will get this nuked (cause we aren't allowed to mention names of meds on the Forum), but I prefer CVS (store) store brand of Actifed (anti-histamine, as it is the only place I can find it and a number of others things do the same!). I'd try it and see if that helps! The fact you can read this is a good sign, it is most likely not serious. A visit to the doc would clear it this up asap! I don't tinker with my vision, as you only get one set of eyes! Don't mess with your vision!

My vision gets a little 'burred' due to allergy! Apparently, your vision is normally better than 20/20, which is highly probable!
