I want to know what's wrong with my left eye and if it is something serious?

Okay, I have started noticing that my left eye is slightly bulging and doesn't have the eyelid crease like the right one. It looks slightly larger too. Also when I pull the eyelid upward to see the white part of the eye, I can see like an indent on my right eye that I don't see on my left eye. My left eye feels kind of stiff, but my right eye feels soothing, my vision is really good and I don't need glasses. It will be a great help to tell me how to fix this I will be really grateful. Thankyou
