Eye floaters are small spots that drift across your field of vision, and they are a common phenomenon that most people experience at some point in their lives. While eye floaters are usually harmless, they can sometimes indicate a more serious underlying condition. Eye floaters are typically caused by age-related changes in the eye, specifically the deterioration of the vitreous humour, a gel-like substance in the eye that begins to liquefy and shrink with age, forming clumps or strands that cast shadows on the retina. While the ageing process is the most common cause of eye floaters, they can also be caused by other factors such as eye injuries, eye surgery, retinal tears, and eye infections. Although eye strain is not a direct cause of eye floaters, it can make existing floaters more noticeable.
| Characteristics | Values |
|---|---|

What You'll Learn
Eye floaters are not caused by stress or eye strain
While stress and eye strain have been linked to an increase in eye floaters, they are not the direct cause of eye floaters.
Eye floaters are typically caused by the deterioration or liquefaction of the vitreous humour, a gel-like substance that fills the eye's main cavity. As people age, this fluid can begin to liquefy and shrink, forming a gel-like substance that clumps or strands inside the eye. This process is known as vitreous detachment, and it causes the brain to perceive flashes of light and dark shadows on the retina, which appear as eye floaters.
Stress and eye strain can contribute to the perception of eye floaters by causing constant pupil dilation and eye strain, making the floaters more noticeable. Additionally, stress can lead to eye strain, inflammation, and headaches, which can also increase the perception of eye floaters. However, stress alone cannot be the sole cause of eye floaters, and other factors related to aging or underlying eye conditions are typically the primary causes.
While eye floaters are generally harmless and often fade over time, they can be bothersome and interfere with vision. If eye floaters are causing significant problems or concerns, it is recommended to consult an eye doctor for an examination and potential treatment options, such as eye surgery or laser therapy.
To reduce the incidence of eye floaters, it is recommended to manage stress effectively, rest the eyes by taking frequent breaks from screens, and maintain a healthy diet and hydration levels. These proactive measures can help prevent eye strain and reduce the likelihood of experiencing eye floaters.

Floaters are usually caused by age-related changes
While eye floaters can be caused by several factors, the most common cause is age-related changes within the eye. Floaters are usually benign and harmless, but they can be a nuisance. As people age, the gel-like fluid in the vitreous, or the middle of the eye, starts to liquefy, shrink, and contract, forming clumps or strands that cast shadows on the retina, which are perceived as floaters. This process can begin as early as 50 years of age and is more common between 50 and 70 years.
The retina is responsible for vision and is located at the back of the eye. When light passes through the eye, the clumps or strands in the vitreous fluid block the light, creating shadows on the retina. These shadows are what we perceive as floaters, which appear as small dark specks, dots, transparent strings, or cobweb-like shapes that drift across our vision. They may be more noticeable against bright backgrounds, such as a white wall or the blue sky, and when looking at something solid, like a computer monitor.
Age-related eye floaters are a natural part of the aging process and are typically not a cause for immediate concern. They tend to be small and few in number, and while they may be annoying, they usually do not interfere with vision and often drift in and out of sight. Over time, they may become less noticeable or even disappear as the brain learns to ignore them. However, it is important to distinguish between age-related floaters and those caused by other factors, as some instances of floaters may signal something more serious.
For example, a sudden increase in the number of floaters, flashes of light alongside floaters, or noticeable vision loss concurrent with floaters could indicate a more severe condition, such as retinal detachment or tears. In such cases, it is recommended to consult an eye doctor or seek prompt medical attention. Additionally, individuals who are nearsighted, have had previous eye injuries, are above 65 years of age, or have a family history of retinal issues or specific medical conditions should pay close attention to any changes in their floaters and consult a doctor if needed.

They are small spots that disrupt your view
Eye floaters are small spots that drift across your field of vision, disrupting your view. They are caused by the deterioration of the vitreous humour, a gel-like substance that fills the eye's main cavity. As people age, this fluid can begin to liquefy and shrink, forming tiny clumps or strands that cast shadows on the retina. These shadows are perceived as eye floaters.
While eye floaters are typically harmless, they can be annoying and bothersome. They are usually small, few in number, and may be perceived as dark specks, transparent strings, or cobweb-like shapes. They don't block your entire view but can be more noticeable against bright backgrounds, such as a white wall or the blue sky.
The appearance of eye floaters can be affected by various factors, including head position, movement, brightness, background, and fatigue. They may be more prevalent if your eye has been injured or you've undergone eye surgery. For most people, eye floaters develop between the ages of 50 and 70, but they can also occur in younger individuals.
While eye floaters usually do not require treatment, it is important to monitor any changes or new developments. If you experience a sudden increase in floaters, flashes of light, or noticeable vision loss, it is recommended to consult an eye doctor as soon as possible. In rare cases, eye floaters can be a symptom of a more serious condition, such as retinal detachment, which requires immediate medical attention.
It is worth noting that stress alone is not responsible for causing eye floaters. However, stress can contribute to eye strain and make pre-existing floaters more noticeable. Therefore, while stress may not be the direct cause, it can play a role in making eye floaters seem more prominent.

Floaters are caused by the deterioration of the vitreous humour
Eye floaters are a common phenomenon, with almost everyone experiencing them at some point in their lives. They are usually harmless and are a natural part of the ageing process. Floaters are caused by the deterioration of the vitreous humour, a clear, jelly-like substance that fills the eyeball's main cavity. This deterioration occurs as people age, causing the vitreous humour to liquefy and shrink, resulting in changes to its thickness.
The vitreous humour acts as a shock absorber and helps maintain the shape of the eyeball. It is composed of more than 98% water but is 2 to 4 times more viscous. As the vitreous humour pulls away from the retina and degenerates with age, small shreds of jelly can break off and form floaters. These floaters are suspended in the vitreous humour, allowing them to move around as the eyes move. They cast shadows on the retina, which is responsible for vision, and these shadows are perceived as eye floaters.
While most eye floaters are benign, there are certain instances where they may signal something more serious. If you experience a sudden appearance of numerous new floaters, it is important to seek prompt care from an eye specialist. Additionally, if you notice flashes of light (photopsias) alongside floaters, experience vision loss, or have eye pain, redness, or light sensitivity, it is advisable to schedule an eye appointment for further evaluation.
It is worth noting that stress alone is not responsible for eye floaters. However, stress can cause constant pupil dilation, leading to eye strain, which may make pre-existing floaters seem more noticeable. While stress does not directly cause floaters, it can contribute to making them more prominent in one's field of vision.

They are harmless but can indicate a more serious eye problem
While eye floaters are usually harmless, they can sometimes indicate a more serious underlying eye problem. Eye floaters are typically caused by the ageing process, but they can also be caused by injury, inflammation, or infection. In rare cases, they can be a symptom of a more serious condition, such as retinal detachment or tears, which can cause permanent vision loss or blindness if left untreated.
Retinal detachment occurs when the retina separates from the back of the eye. Symptoms of retinal detachment include a sudden increase in floaters, bursts of light across your field of vision, and a loss of peripheral vision. If you experience any of these symptoms, it is important to contact your doctor right away.
Other signs that your eye floaters may be indicative of a more serious problem include:
- The sudden appearance of numerous new floaters
- Flashes of light alongside eye floaters
- Noticeable vision loss
- Eye pain, redness, or light sensitivity
- Post-cataract surgery complications
It is important to note that stress alone is not responsible for eye floaters. However, stress can cause eye strain, which can make pre-existing floaters seem more noticeable. If you are experiencing eye floaters, it is always a good idea to maintain regular eye exams, especially if you notice any changes or increases in floaters, flashes, or vision problems.
