My eyes seem to be very light sensitive. Could this be a big problem?

My eye sight isn't the greatest, but it never really was a problem. I have a really low prescription right now that I got two years ago and I have an appointment for the optometrist next month. I've noticed that when I'm dealing with indoor lighting my eye sight feels 5x worse than usual. It kind of feels like I've been staring at the light for too long and it's following my line of sight except not as bad as concentrated light, just kind of distorted. Has anyone ever had a problem like this and know what it is? Or is anyone an eye doctor that's seen something like this before?
