Understanding Eye Floaters: Causes, Risks, and Treatments
What Are Eye Floaters?
Eye floaters are small, squiggly shapes that float across your field of vision. They can appear as spots, threads, or lines, and they’re especially noticeable against bright backgrounds like a clear sky or a white wall. These floaters move with your eye, often seeming to dart away when you try to focus on them.
Why Do Floaters Happen?
Most floaters are caused by changes in the vitreous, the gel-like substance inside your eye. As you age, the vitreous becomes more liquid, and tiny fibers within it can clump together. These clumps cast shadows on the retina, which is what you see as floaters.
Who’s at Risk?
Certain people are more likely to experience floaters, such as those who are nearsighted, have had cataract surgery, have diabetes, or are getting older.
When to Worry About Floaters?
In most cases, floaters are harmless. However, if you notice a sudden increase in floaters, flashes of light, or a dark shadow in your peripheral vision, it could mean a retinal tear or detachment. These are emergencies that need immediate medical attention.
How Are Floaters Diagnosed?
To check for floaters, your eye doctor will perform a dilated eye exam, where they use drops to widen your pupils. This gives them a better view of your vitreous and retina to look for any serious problems.
What Are the Treatment Options?
In most cases, floaters don’t require treatment as they tend to become less noticeable over time. However, for those who experience vision problems, options include:
- Vitrectomy: A surgery that removes the vitreous gel and replaces it with saline.
- Laser Therapy: A laser breaks up floaters, making them less noticeable.
Both treatments carry risks and are usually reserved for severe cases.
Managing Floaters
If floaters are bothering you, simple lifestyle changes can help:
- Eye Exercises: Moving your eyes up and down may shift floaters out of view.
- Healthy Diet: Eating foods with omega-3, vitamin A, and zinc supports eye health.
- Avoid Smoking: Smoking can worsen eye problems.
Regular eye check-ups are important, as they can catch serious issues early. If you notice any changes in your vision, don’t hesitate to consult your doctor.
