I think my contacts are effecting my ability to see other's auras. When I have my glasses on (or just not wearing them in general, actually...) I can see auras perfectly fine.
Should I practice more on viewing auras through my contacts?
I see auras easier without my glassess too. The problem is, im actually terribly blind, so i nearly have to be on top of the person im looking at for their aura at this point. But im getting better. So id say yes, practice will make it easier. You might get a small headache if you try too hard and dont relax.
