Eye dryness, floaters. What should i do?

I am a 21 old year male. About one month ago I had burning sensation in my eyes and i had to go to the eye doctor and get medical check up. It came out normal and the doctor prescribed me "Extralube" to ease the burning. In a week i got fine but after that when I ran out of that Extralube, burning started a little bit when i travelled in train and at night light sources looked a bit stretched or slight double, doc said it was fine and did not prescribe Extralube again. Now about two weeks ago I started seeing floaters. I again got a medical check up of my eyes ( 10 days ago) and again it came out normal, the doctor prescribed no medicine. last 10 days were good, I used two see 2 small floaters at my home and 3 or 4 at outside but yesterday as I woke up I still see two floaters at home but outside of home i think the floaters move faster as compared to earlier and they are 3 or 4 or 5. My eye doc is on a leave till this monday and im stressed please suggest what should i do
