The floaters are likely nothing, and just a fact of life and aging. Yes even at 22 'age related' things occur.

Floaters are changes in the vitreous humor (jelly like substance in the eye). Their reflection in the path of light reflected to the retina is what you see.

Many if not most people have them to some degree. Check each eye independently against a blue sky or bright white background (ie: Computer screen).

Should be a little different in each eye.. one eye may not have any.

I personally got my first one at 15,.. and am now 31 and have a considerable amount more. That are annoying.

In MOST people they are suppressed naturally by the brain. At first you notice them for a while.. but eventually the brain 'filters' them out. A common process that is automatic. You can usually 'find' them again if you look for them but just generally not paying attention to it they won't bother you in time.

With all of that said -- It would not be a BAD idea to see an optometrist for a general eye exam, especially if it has been a little while since your last. Tell them of the recent floaters -- they will easily be able to detect a retinal detachment which is the main danger with a large amount of 'new' floaters. Have you seen any 'sparks' in the vision lately -- if so, you really need to get to the eye doctor.

Don't let it worry you, it is 99.9% just normal process of the eye.
