Wonderful! I'm glad that everything turned out okay for you. You're right in that the floaters do tend to manifest themselves more against a bright background. I hope that getting the glasses checked and changed may help your headaches, but if not, I would suggest seeing your primary care doctor about them if they are significantly bothering you.
I hope you continue to do well and I'm happy to help you. Also, thank you for the update--I'm glad to see you're doing better. Take care and Happy Holidays!
