Hi doctors. May i ask if is it possible for a droplet of fluid will get into our eyes without us knowing or feeling it? It was when i hold a testtube of blood in it's head/cap (the tube was in the table infront of me and i used just my right hand to hold it) and i felt that the cap was loosened. To my fear, i called my colleague to tighten the cap. Now i am worried that there may be droplet of blood got into my eyes although i didnt feel anything, or blink my eye and i keep thinking about it until now. Please help. thank you.
