Threads, dots and cobwebs drift across your vision, and the internet promises everything from eye drops to surgery. This is a calm walkthrough: what floaters are, when they are genuinely urgent, who deals with them, and which options actually make sense.
Flashes, a curtain or a sudden shower of new floaters — see an ophthalmologist within 24 hoursMove your cursor over the sky or touch it — the opacities will drift after it with a delay
Detachment modelMechanism
The vitreous is a clear gel that fills the eye. With age and with myopia it liquefies, its collagen fibres clump into strands, and those strands cast shadows on the retina. That shadow is what you see as a floater.
Perception
How bad the symptoms feel has little to do with the number of opacities. What matters is their density, their distance from the retina and how much attention you pay to them.

Two scenarios
Age-related syneresis and posterior vitreous detachment (PVD). It is a natural process, not a disease: sooner or later it happens to almost everyone, and noticeably earlier in short-sighted people.
As the vitreous detaches, the gel pulls on the retina. In some people this causes a tear, and an untreated tear leads to retinal detachment and vision loss.
Roadmap
First rule out the dangerous scenarios, then work on comfort. Doing it the other way round is the most common mistake, and it's how retinal tears get missed.
There is one key figure: an ophthalmologist who examines the retina through a dilated pupil. Everyone else is brought in depending on the situation, and many patients never need them at all.
Flashes, a curtain, a shower of new floaters, “soot” — see an ophthalmologist within 24 hours, not at a convenient date.
The essential baseline: dilating drops, an exam of the fundus and periphery. Without dilation a retinal tear can simply be missed.
B-scan ultrasound if details can't be seen, macular OCT, and if inflammation is suspected — blood tests and a rheumatologist consultation.
It's important to understand exactly what you have: age-related syneresis, a completed PVD, vitreous haemorrhage or uveitis. Each is managed differently.
A repeat exam after a fresh PVD: some retinal tears don't appear straight away. If there is a tear — laser photocoagulation.
Six months of observation and everyday adjustments. Track how things change: whether it gets easier and whether the picture shifts.
If after 6 months the symptoms are unchanged and interfere with work — discuss YAG or vitrectomy with a vitreoretinal surgeon.
With myopia and after surgery — regular exams of the retinal periphery and knowing the red flags by heart.
Options
There aren't many options, and they are listed in order of increasing risk. You always start with observation; invasive methods are discussed only when symptoms persistently disrupt everyday life.
Risk to the eye →
The main scenario: opacities settle below the visual axis and the brain stops singling them out. For most people the discomfort drops noticeably over weeks and months — without any intervention.
Self-assessment
This question matters more than the number of opacities: how much they affect your daily life determines whether you stay under observation or go on to discuss an intervention.
Mark how true each statement has been for the past month. This is a rough self-assessment of the impact on daily life, not a diagnostic test.

Regardless of your score
Flashes of light, a dark curtain and a sudden shower of new floaters aren't about quality of life — they call for an urgent retinal exam within 24 hours.

Questions
Short answers to what people usually ask at their first appointment.
They rarely disappear completely, but they often stop bothering you. Opacities drift downward, become less dense, and the brain stops noticing them. That's why the standard approach to uncomplicated vitreous opacities is observation, not treatment.
Vitreous degeneration itself doesn't threaten your sight. The dangerous moment is the vitreous detachment: in a small percentage of cases it causes a retinal tear, which without treatment leads to detachment. That's why a first visit with pupil dilation is essential, even if the symptoms seem trivial.
No. A screen doesn't cause vitreous degeneration, but it makes it more noticeable: a bright, uniform background is the ideal condition for seeing a shadow on the retina. That's why it feels like there are more floaters by the end of a working day.
With uncomplicated vitreous opacities there are no restrictions. Situations with a recent retinal tear, after laser photocoagulation or surgery are discussed separately — there your ophthalmologist will set the rules.
Most often because of myopia: in an elongated eyeball the gel liquefies earlier. Less often the cause is past inflammation, injury or bleeding. Being young doesn't mean you can skip an eye exam.
