Insight on Eye Floaters and How They Can Impact Your Vision


0218507001631133390.jpgEye floaters appear as dots or strings in your vision. If you’re seeing them, you probably want to know why! At Eye On Health here in Phoenix, our optometrist cares about answering your eye and vision-related questions.
We love educating our patients, and this common topic comes up for a lot of people. In most cases, age-related changes in the back of the eye cause these floaters. The vitreous, a jelly-like substance in our eyes, becomes more liquidity or thicker with age.

While this eye issue is annoying, we hope to reassure you that most of the time floaters are normal. But keep reading to find out when they aren’t!


What Are Eye Floaters and Why Do You See Them?


Ever swat at a fly only to realize there isn’t actually a fly there? What a strange moment. It’s a common way people experience floaters for the first time, so know you’re not alone.

Floaters can take many shapes, like:

  • Specks
  • Dots
  • Strings
  • Blobs
  • Lines
  • Cobwebs

It seems like they’re in the front of your eyes, but they’re actually floating in vitreous gel in the back. When light hits the front of our eyes, it casts shadows on our retina. The retina is a sensitive layer covering the inside of our eyes and detects light.

So those tiny little specs float around inside your eyeball! (We think it’s kinda neat – as long as it’s not indicating a serious medical issue.) Because floaters cast shadows when light enters your eye, you may notice them more on a bright blue sky or snowy white background — when light reflects more intensely.


What Causes Eye Floaters and the Symptoms You’ll Notice


The main cause of floaters happens when the vitreous gel in the back of our eyes changes as we age. (Ah, the fun “age” word we know you love reading about. But in keeping with our name, we like to offer valuable insight so you keep a watchful Eye On Health.)

As we get older, the vitreous gel begins to thicken or gets more liquidity. When either of these occurs, small pieces of the vitreous can pull away from the back of the eye (retina) and float around the back of your eye. [1]

You may notice: As you move your eye left or right, the floaters move. It’s because they’re actually moving! Floaters occur during the normal aging process, but keep reading to learn when they’re considered a medical emergency.


Other common causes for floaters include [1]:

  • Swelling inside the eye
  • Cataract surgery
  • Nearsightedness (when you need glasses or contacts to see far away)

The symptoms of this eye issue are pretty straightforward — you see little shapes and spots moving around in your vision. Most of the time, they eventually settle out of view. And over time, your brain learns to ignore them (whew!).

In very, very rare cases severe floaters need to be surgically removed by a specialist.

Sometimes floaters change, so it helps to know when you should visit your eye doctor.


When Eye Floaters Are Considered a Medical Emergency


Most of the time, floaters are normal. But there are always outliers in everything, right? We want you to know when it’s time to take action to save your eyesight.


You need to see an eye doctor if you experience [2]:

  • A lot more floaters than usual
  • Sudden onset of floaters
  • Loss of any peripheral (side) vision
  • Flashes of light

When floaters increase or are associated with other symptoms –  a very serious situation develops. When the vitreous gel changes in our eyes, it can pull on and damage the retina.

This pulling sensation causes flashes of light, and in severe cases, can cause a retinal tear — which is a medical emergency. Retinal tearing can lead to retinal detachment and blindness. We’re not trying to scare you! The more you know, the better prepared you are to prevent these emergencies.

If you experience light flashes or any other symptoms listed above, get yourself to an eye doctor immediately. 

0043904001631133472.jpgA study found that people with more than ten floaters and flashes of light in one eye had a greater chance of a retinal tear. [3] So pay attention to your symptoms and remember these warning signs.
When the retina tears, some people notice a sudden burst of floaters or experience very cloudy areas in their vision. Take these symptoms seriously to preserve your eye health and vision.
