Eye Floaters: Overview, Symptoms and Causes

Have you ever observed thread- or web-like shapes drifting across your vision, especially when staring at a bright surface? These are known as eye floaters, and they’re a common visual phenomenon experienced by many people. Floaters appear as small shapes that move as your eyes move, often looking like spots, squiggly lines, or cobwebs. They are typically caused by age-related changes in the vitreous, the gel-like substance inside your eyes, which can shrink or clump over time, casting shadows on the retina. While they’re usually harmless, a sudden increase in floaters or flashes of light could indicate a more serious condition like a retinal tear or detachment. Mild floaters often require no treatment, but in more severe cases, options like laser therapy or vitrectomy may be recommended. Most people learn to live with floaters without much trouble, as the brain gradually adapts and tunes them out over time. Learn more about what causes eye floaters, eye floaters symptoms, its prevention and treatment options.

What is Known as Eye Floaters?

Eye floaters (also defined as floaters) are tiny dots in your range of vision that occur when you stare at a light-coloured region (such as a white wall or blue sky). They form when tiny clumps form in the clear, jelly-like substance inside the eyeball (the vitreous humour). Eye floaters (the black spot in the eye) are suspended in this ‘jelly,’ and they move in tandem with your eyeball. If you try to look at them directly, the black floaters in the eye may appear to vanish.

A large floater may cast a shadow over your vision. However, this only happens in certain types of light.

Floaters are very common and are a natural part of the ageing process for many people. The causes of floaters are not exactly known. The majority of the time, the black floaters in the eye do not require treatment because they do not harm one’s vision. Eye floaters (the black spot in the eye), on the other hand, can make it difficult to see in some cases, necessitating their removal to restore vision. Floaters may become less noticeable over time, but they are permanent and remain in the eye.

Contact an eye specialist right away if you notice a sudden increase in floaters, especially if you’re also seeing light flashes or losing your peripheral vision. These could be signs of a serious emergency that requires immediate attention.

Types of Eye floaters

1. Cobweb-shaped, wavy or squiggly

The black spot in the eye that appears in your vision is wavy or squiggly lines are the most common. They’re called “cobweb” floaters because they tend to float around your vision like broken cobweb pieces.

2. Spots, circles, and other rounded forms

Some black floaters in the eye have the appearance of small rounded spots or oblong ovals. Wavy and rounded floaters are identical to each other; the only difference is the shape of the vitreous fibre formation.

3. Floaters that are transparent, shadowy, or black

Floaters in the eyes can be almost transparent, slightly shadowy, or nearly black.

The colour of someone’s floaters, like their shapes, can vary. Floaters in the eyes can be nearly transparent, slightly shadowy, or nearly black.

4. Seeing “stars” in your vision

It’s not uncommon for people to see “stars” or small flashes of light in their vision. Although these flashes (photopsia) are not physical formations like floaters, they may be connected.

Eye Floaters Symptoms

Eye floaters (the black spot in the eye) can cause the following eye floaters symptoms:

• Dark specks or knobby, transparent strings of floating material appear as small shapes in your vision.
• When you try to look at spots that move when you move your eyes, they quickly move out of your visual field.
• Spots that stand out the most against a bright background, such as a blue sky or a white wall
• Small shapes or loops settle into place and eventually disappear.

What Causes Eye Floaters?

Eye floaters most commonly arise due to age-related changes within the eye, particularly in the vitreous humour—the clear, gel-like substance that fills the inside of your eyeball. As we age, the vitreous gradually becomes more liquid, a process known as vitreous syneresis. During this change, tiny fibres and proteins in the gel start to clump together, casting shadows on the retina as light passes through. These shadows appear as floaters drifting across your field of vision.

The retina, located at the back of the eye, is responsible for processing the light that enters through the cornea and lens at the front. When debris from the deteriorating vitreous humour interrupts this light path, you perceive those shadows as floaters. This process is a normal part of ageing and is especially common after the age of 50.

Besides ageing, several other factors can lead to the formation of floaters:

• Eye injury: Trauma to the eye, whether from impact or an accident, can disrupt the vitreous, triggering the sudden appearance of floaters.
• Nearsightedness (Myopia): Individuals who are nearsighted are more prone to floaters due to the elongated shape of their eyes and the faster breakdown of the vitreous.
• Inflammation (Uveitis): Infections or autoimmune conditions that cause inflammation inside the eye can also produce floaters, as inflammatory debris accumulates in the vitreous.
• Diabetic Retinopathy: Diabetes may damage the tiny blood vessels in the retina. When these vessels leak or rupture, they can introduce blood or debris into the vitreous, creating floaters.
• Vitreous Deposits: Sometimes, crystal-like deposits develop in the vitreous, interfering with light transmission and leading to visual disturbances.
• Intraocular Tumours and Ocular Migraines: Though rare, certain tumours or visual disturbances like ocular migraines can also manifest as eye floaters.

Are Eye Floaters (the black spot in the eye) in the Eyes Inherited?

As people get older, they may develop floaters in their eyes. Causes of floaters can result in retinal tears or detachment, which may be inherited. You may be at a higher risk of developing retinal detachment or tears if you have a family history of them. Floaters and flashes in the eyes could indicate retinal detachment or tears.

Other risk factors related to your vision — specifically nearsightedness — can be passed down through your family. If you’re nearsighted, you may be more likely to develop floaters. This could lead to retinal detachment in the long run.

When it comes to the black spot in the eye, however, many people have no family history of retinal detachment or retinal tears. It’s important to remember that black floaters in the eye are a common side effect of ageing and occur naturally over time.

Eye Floaters Treatment

Surgical removal of floaters is an option, but it comes with a lot of risk to your vision. When a large number of floaters are obstructing your vision, a procedure called a vitrectomy can be used to remove them. The gel-like vitreous inside your eye is removed through incisions during this surgical procedure. It is then replaced with a vitreous-mimicking solution. This procedure comes with several risks, including:

• Retinal detachment is forming.
• Tears in the retina are forming.
• Not being able to remove all of the floaters from your eye.
• Cataracts are forming.
• This surgery carries the risk of causing vision loss. As a result, before deciding on this treatment path, many providers will carefully discuss all of the benefits and drawbacks of this elective procedure.
• Eye floaters (the black spot in the eye) may be treated with a laser at times by your provider. This can help to break up floater clusters and move them out of your field of vision. There is also the possibility of side effects with this procedure.

There are no home remedies for getting rid of eye floaters. They are, unfortunately, a common side effect of growing older. They will fade and become less noticeable over time, but they will never truly vanish.

Prevention of Eye Floaters

Although eye floaters (the black spot in the eye) cannot be prevented, it is still beneficial to follow some basic practices to keep the eyes healthy. These are some of them:

• Lose weight or maintain a healthy weight
• eat a well-balanced and nutritious diet
• smoking cessation
• Sunglasses should be worn outside
• When necessary, put on protective eyewear.
• Eyes should be rested frequently.
