My left eye started itching in the early morning of

Patient: My left eye started itching in the early morning of yesterday when I had left my make up on and it felt like I had grit or something in the corner of my eye causing it to itch worse. When I checked there was nothing there and after waking up today it seems its only at night when this gritty feeling is present. My eye keeps running and its a little red and swollen inside. However I have also not been able to stop sneezing this morning. Could I have conjunctivitis? If so is it pollen that caused it or my makeup being left on? Im partly sighted in my right eye which is why it us concerning me as I don’t want to infect both.
