Floaters are drifting specks and threads that appear when the gel inside the eye pulls away from the retina. Most are an ordinary part of getting older. Three specific changes are not, and they need an eye doctor the same day.
Most new floaters are the eye getting older, not the eye failing. They usually fade from notice within a few months.
The vitreous is the gel that fills the eye. With age it turns to fluid, collapses, and peels away from the retina. The strands it leaves behind cast the shadows you see drifting past.
Here is what ordinary floaters look like. Then the three changes that are not ordinary, and why the exam schedule matters more than the floaters do.
Six Things You Might See, and Three That Are Not Ordinary
Floaters look like specks, cobwebs, hairs or dust. They drift across your vision and move when your eye moves. Some people see a small circle or oval, which has a name: a Weiss ring.
The National Eye Institute says the most common symptom of vitreous detachment is a sudden rise in floaters. Flashes of light off to the side often come with it.
- A few new specks or threads after age 50. Vitreous detachment is rare before 40 and usually starts after 50. Cleveland Clinic notes the floaters may keep changing size and shape for four to six weeks while the gel finishes separating.
- Floaters that drift when your eye moves. They sit inside the eye, so they lag behind your gaze and settle when you stop moving. Anything fixed in one spot is a different problem, and still needs an eye doctor.
- Floaters that become less noticeable over months. Cleveland Clinic says they usually become less noticeable within a few months, as your brain learns to ignore them.
- Call today: a sudden shower of many new floaters. Not one or two more. A sudden burst of them is the sign that the gel has pulled hard enough to risk tearing the retina underneath.
- Call today: flashes of light, usually off to the side. Mayo Clinic calls these photopsias. They mean the retina is being tugged, and they are easier to notice in a dark room.
- Call today: a curtain or shadow across part of your vision. Mayo Clinic lists a curtainlike shadow, and worsening side vision, among the signs of retinal detachment. That is an emergency, and it is painless.
None of this hurts. The Mayo Clinic is direct about it. Retinal detachment is painless. Its warning signs are things you see, and nothing else.
That is the whole trouble. There is no ache to react to. What you see is the only alarm you get.
Why One Dilated Exam Settles the Whole Question
You cannot tell a harmless detachment from a torn retina in the mirror. You cannot tell over the phone either. Someone has to look at the back of the eye.
The National Eye Institute puts it plainly. A dilated eye exam is the only way to tell if a vitreous detachment has caused a serious problem. That is why new floaters mean going in right away.
Drops widen the pupil so the clinician can see the edge of the retina. That edge is where tears usually start.
Cleveland Clinic says the exam is usually painless. Pressing on the eyelids to check for tears can be uncomfortable. If the back of the eye cannot be seen clearly, an eye ultrasound can map it instead.
The only way to tell if vitreous detachment has caused a serious eye problem is to get a dilated eye exam.

A clean first exam is not the end of it. The gel is still separating. A tear can show up in the weeks after that first look.
The Cleveland Clinic instruction is specific. Have an eye exam when your symptoms start, then again four to six weeks later.
The second visit exists because the first can be honestly clear and still miss what has not happened yet. Cleveland Clinic says the provider checks for anything missed, and anything new.
There is one more reason to keep it. Both the National Eye Institute and Cleveland Clinic say that once one eye has done this, the other is more likely to follow. Often within a year or two.
Three Floater Beliefs Worth Dropping Today
Three corrections worth carrying into the appointment.
Floaters can be flushed out with drops or vitamins. Nothing you put on the surface of the eye reaches the gel inside it. Neither source lists a drop, a vitamin or an exercise that removes a floater. The only removal either names is surgery.
Surgery is the obvious fix if they bother you. It is a last resort. Cleveland Clinic says surgery for floaters is rare, because of the risk. It says to see a retina surgeon first. The National Eye Institute says to weigh the risks before agreeing to one.
No pain means no emergency. The reverse is closer to true. Mayo Clinic says retinal detachment is painless. It also says the longer it goes untreated, the greater the risk of losing sight in that eye for good.
