Hi, Ive Had Something Stuck In My Eye Since About

Hi, ive had something stuck in my eye since about 18 hours ago, when it first happened i was walking and it felt like something flew into my eye, i looked in the mirror when i got home but i couldnt see anything in it, but it still felt like there was something in my eye right in the corner closest to the nose, i went to sleep and woke up and its still there, mainly when i close my eye or blink i can feel it.
