Eye floater. Medicine for ocd. help me!

I had eye check-up today at indira Gandhi eye Care hospital & research centre. They said I have harmless vitreous eye floater in my right eye.this eye floater is disturbing my eye vision and irritate me most of time for 2 years. When I asked its size is normal She said yes and mostly aged people have this not young people. But all my young  friends have such type of eye floater. Actually she didn't give me satisfying answer. Now I am unable to understand how I compare my floater size with others. How I know my eye floater size is of average size  that most young people generally have this or my floater size is bigger Should I continue physchiatric medicines to cope up with this.  As I am taking phschiatric medicine for OCD.
