I know it isn't just me because my boyfriend says he has the same issue, but every time I get new glasses thinks look worse before they look better. I also suffer from vertigo issues and new glasses just exacerbates them. My old glasses were -really- old and I was well overdue for new ones, and I think that's half my problem in trying to get adjusted to these new ones. I have an astigmatism so my prescription is always changing. I haven't had new glasses for six years. Oops. It certainly isn't the end of the world but it sure is uncomfortable. Any one else have these issues when they get new glasses??
