If you experience any of these symptoms you should seek medical advice within 24 hours. This is particularly important if you notice a dark 'curtain' falling across your vision, as this may mean that the retina has already partially detached. Early intervention may allow treatment of a tear before it becomes a detachment and increase the chances of a good recovery from a retinal detachment which has already occurred. They will pay special attention to whether or not the retina is in any danger. If it isn't then they may not need to see you again.
Floaters can be particularly annoying.
They get in the way of seeing things and can make some things difficult, for example reading a book. There is a way of trying to cope with this that some people find useful. If you move your eyes around you can create currents in the jelly within your eyes this can sometimes move the floater out of your direct field of vision. This works best if you have one large floater rather than lots of small ones. Making things bigger can also help while you have floaters so that you are able to see things around the blank spots the floaters cause.
