I have noticed at times that in buildings such as at worship services, that it seems like there is not enough light to see well. I figure it is just me. I also have problems with reading sometimes-the words seem to be moving about on the page like someone is moving my book back and forth. This isn't often though, thank goodness. I also have just started having problems with being able to see up close, but since I am 42, I guess that is just presbyopia creeping in on me.
