There is like a lens flare, what should I do?

I noticed like a lens flare (colored object in my left and right lens, refer to pictures.) All my research points to sunlight exposure but its never been outside and I live in a basement apartment (no windows in my office), could it have been the lightbulb in my office? or could it be something else? I'm out of the warranty time frame so my I'm not 100% what my options are.
