I'm doing a sort of vision theme this week at worthless word - so far I've got
cosmopsis - the cosmic view
autoptic - seen (for) oneself

tomorrow's word means 'lack of vision'
but, so far, I'm drawing a blank for Friday.

I've not tried soliciting suggestions for a particular topic before, but...

edit: the kind of thing I've done previously:
vatic, vaticide, vaticinate, vaticination, presagition, perscrutation, perspicuous

Psst-- take your pick

homonymous hemianopsia?

in the event, I did something like that within the OED..

So what am I to to with this? the worthless word for the day is: dementate. Is my vision obscured? Or do you have double agendas?
