ProComp/Speedmaster aluminum heads

I literally had a doctor chase me to the corner of the room and stabbed my arm to get a needle in me! I absolutely detest needles!
If you've had more than excellent vision for 50 years plus and you wake up one morning and three quarters of your vision is gone in your left eye, your attitude changes about certain things. For instance you completely lose your depth perception up close and you have to ask your (very nice) gay neighbor across the street if he could come over and put the second bead of RTV on top of your first bead on the China wall because you can't....
When you're faced with not being able to see your grandkids correctly and stuff like that you start to look at that needle a whole different way... LITERALLY!
I'd say it brought it back to about eighty-five 90% good in my left eye with the shot... it's still a little bit irritating sometimes cuz I notice it but it certainly has brought my vision back to where I can put my second bead on top of my first bead on my China Wall myself....
So whats wrong with your eyes?, do you go to Casey eye institute?, all too familiar with that stuff!
