Eye floaters appear as small spots that drift through your field of vision. They may stand out when you look at something bright, like white paper or a blue sky. They might annoy you, but they shouldn’t interfere with your sight.
If you have a large floater, it can cast a slight shadow over your vision. But this tends to happen only in certain types of light.
You can learn to live with floaters and ignore them. You may notice them less as time passes. Only rarely do they get bad enough to require treatment.
What Are the Symptoms?
Floaters earn their name by moving around in your eye. They tend to dart away when you try to focus on them. They come in many different shapes:
• Black or gray dots
• Squiggly lines
• Threadlike strands, which can be knobby and almost see-through
• Cobwebs
• Rings
Once you get them, they usually don’t totally go away. But you usually notice them less over time.
Most floaters are small flecks of a protein called collagen. They’re part of a gel-like substance in the back of your eye called the vitreous. As you age, the protein fibers that make up the vitreous shrink down to little shreds that clump together. The shadows they cast on your retina are floaters. If you see a flash, it’s because the vitreous has pulled away from the retina. If the floaters are new or dramatically changed or you suddenly start seeing flashes, see your eye doctor ASAP.
These changes can happen at any age, but usually occur between 50 and 75. You’re more likely to have them if you’re nearsighted or have had cataract surgery.
It’s rare, but floaters can also result from:
· Eye disease
· Eye injury
· Crystal-like deposits that form in the vitreous
· Eye tumors
Serious eye disorders associated with floaters include:
• Torn retina
• Bleeding in your vitreous
· Inflamed vitreous or retina caused by infections or an autoimmune condition
• Eye tumors
Something that might resemble a floater is the visual aura that can come with a migraine headache. It could look like what you see when you put your eye to a kaleidoscope. It might even move. It’s different from the floaters and flashbulb type “flashes” that come with other eye problems. This usually lasts about 30 minutes or less, and may involve the vision in both eyes. It completely resolves unless you have another episode.
When to See the Doctor
If you only have a few eye floaters that don't change over time, don’t sweat it.
Go to the doctor ASAP if you notice:
• A sudden increase in the number of floaters
• Flashes of light
• A loss of side vision
• Changes that come on quickly and get worse over time
• Floaters after eye surgery or eye trauma
• Eye pain
Treatment
Benign floaters almost never require medical treatment. If they annoy you, try to get them out of your field of vision. Move your eyes, as this shifts the fluid around. Look up and down, which usually works better than side to side.
If you have so many that they block your vision, your eye doctor may suggest surgery called a vitrectomy. They will remove the vitreous and replace it with a salt solution.
Here is to your good health!
