I don't use shooting glasses. The recticule always looks fuzzy and/or grainy to me in the true holo sights.The red dots don't. I thought that all sights and scopes were parallex free if they were 1X. You can (I can) mount my red dot sights as far away or as close to my eye as possible and the point of aim stays the same.ie where the red dot is,that is my POI.My AimPoint,Optima,and TruGlo sights are very good at keeping point of aim when you "put" the dot up,down,right,left. To me the red dot sights are like scopes in that,you basically get what you pay for. I have friends that have EOtechs on a varity of weapons and they all love them(especially the 1MOA mods) and can see the recticule.
