Given what you have told me It is very possible that you have something going on with the very center (and very important) part of your retina called the macula.
So. What should you do?
Get into see an ophthalmologist (Eye MD) today. An optometrist (OD) is not well enough trained to deal with these sorts of issues in my opinion as a retina specialist......
These sorts of things tend to get worse over time if ignored so go sit in and Eye MD's waiting room until she squeezes you into her clinic schedule today.
And, yes, I could give you a laundry list of possible differential diagnosis for your symptoms but, with the limited data we can share via online chat, that list will be of almost no use to you.
What you really need to know is this:
Get in for a good eye exam. Now.
Make sense to you?
It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.
