If you notice floaters and flashes of light in your vision, you should get your eyes checked by an ophthalmologist (hospital eye doctor). If they diagnose you with PVD, you’ll probably find that your symptoms will change over time.
Floaters can be in different shapes and sizes from small dots to larger cloud shaped spots or long strands. Some people can have lots of small floaters in their vision, while others may have just one or two larger ones.
Most floaters are small and may move around quite quickly in your vision, sometimes disappearing altogether. Some larger floaters may be more noticeable and distracting because they get in the way when you're looking at something. This can be frustrating and make tasks such as reading more difficult.
However, PVD on its own does not cause any permanent loss of vision. Your brain will gradually learn to ignore the floaters and in time, you should see just as well as you did before your PVD began.
