I know that eye exams can be scary because yiur always expecting the worse but calm down. I've been there, many times, sometimes more than once a year, all of my life. Dilation is nit anything to fear. They basically out some drops in your eyes and then tike's have to sit and wait for the effect to take place. It just makes your pupils wider. You dont feel anything except extra sensitivity to light and if you are near or far sighted, your vision will be extra blurry. Sometimes, depending in what drops they use or who knows what, you might feel a very slight stinging from the drops. Sort of like getting sweat in your eye. Nothing major. After the time has passed, the doctor will check your dilated eyes with one hell of a bright light. It takes some time because he will ask you to look up, sideways, downwards, etc. The exam checks behind your eye, your retina, etc. Its fine. No big deal. What your describing doesn't sound like any optical nerve issue. The floaters can be anxiety related, your just noticing them more often. If they are like snow and your also having flashes then in a more rare situation, it could be your retina. Retina issues are completely fixable so take it easy. You will be fine. Good thing is that once you go through this exam, you will be able to continue following them up in a yearly basis and you will not have to worry about eye diseases again.
