When should I worry about eye floaters?

What does it mean when you see spider webs in your eyes?
Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina.
Can dehydration cause eye floaters?
Dehydration is another cause of eye floaters. The vitreous humour in your eyes is made of 98% of water. If you’re constantly dehydrated, this gel-like substance can lose shape or shrink. This can lead to the occurrence of floaters because the proteins in this substance do not remain dissolved and thus, they solidify.

Why do I see a white flash when I close my eyes at night?
As one grows older, the vitreous humor that fills the center cavity of the eye becomes more liquid and begins to shrink. This causes the vitreous to pull away from retina creating occasional bright bursts of light or flashes that are seen when the eyes are closed.
Why does pressing on your eyes feel good?
Rubbing stimulates the eyes’ lacrimal glands, which creates lubrication and gives some relief. And there’s more than just the feeling of an itch vanquished, pressure on the eyes actually stimulates the vagus nerve. That reflex slows down your heart rate and can take you from tired to downright snoozing.
What does flashing lights in your eyes mean?

Is it normal to see images when your eyes are closed?
There’s no doubt that humans have a lot to ‘see’ even when we close our eyes.

In other words, anytime you want to see something spectacular, just try closing your eyes.
