They are caused by an irregularity in the vitreous 'gel' that fills your eye. The irregularity casts a shadow onto your retina, blocking small areas of your vision, which you perceive as floaters. This is usually accompanied by a sudden increase in floaters, and sometimes flashes in your vision as well.

“Visual symptoms include seeing floaters or blood spots. This is common but it is important to have regular eye checks.” Other high blood pressure symptoms include headaches and dizziness. Facial flushing, nosebleeds, nausea and palpitations could also be signs of hypertension.
Intermediate Macular Degeneration: the yellow spots under your retina grow larger and expand, causing blurred spots in the centre of your vision. In this stage you may need more light to read or perform other tasks.
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.
Migraine and stress
This is called a migraine aura. Eye flashes from a migraine aura may appear like jagged lines or cause a person's vision to appear wavy. As stress can be a trigger for some migraine attacks, it's possible there's a connection between stress, migraine, and eye flashes.One common side effect of lack of sleep is eye spasms. Over time, lack of sleep can lead to serious ramifications on your vision including popped blood vessels due to eye strain. Additionally, a shortage of sleep can cause dry eye, a condition when tears do not adequately lubricate your eyes.
Research Findings on Bright Lights and Eye Damage
In experimental mice, bright light does cause permanent retinal damage. If the light has the intensity of sunlight, short exposure times can cause damage. If the light is not quite so bright, chronic exposure over days to weeks can cause permanent damage.In short, yes, staring at bright lights can damage your eyes. When the retina's light-sensing cells become over-stimulated from looking at a bright light, they release massive amounts of signaling chemicals, injuring the back of the eye as a result.
Too much visible light can penetrate your eye and damage the retinal tissue, which causes a condition called solar retinitis. This means parts of your retina can no longer process light normally, so you can end up with entire chunks of your vision blurred out.
In dim light, your pupil expands to allow more light to enter your eye. In bright light, it contracts. More light creates more impulses, causing the muscles to close the pupil. Part of the optic nerve from one eye crosses over and couples to the muscles that control the pupil size of the other eye.
If eye floaters begin to impair your vision, there are treatments available to make them less noticeable or remove them.
- Ignore them. Sometimes the best treatment is nothing at all.
- Vitrectomy. A vitrectomy is an invasive surgery that can remove eye floaters from your line of vision.
- Laser therapy.
Hint: It may be related to your blood pressure
They're attention grabbing for a reason—and it's related to your blood pressure. Each speck represents a blood vessel that's burst. But a red dot or specks could also be a sign that your blood pressure is high, meaning you might have hypertension.During an ocular migraine, or migraine with aura, you may see flashing or shimmering lights, zigzagging lines, or stars. Some people describe psychedelic images. It may also cause blind spots in your field of vision. Ocular migraines can interfere with your ability to perform tasks like reading, writing, or driving.
But warning signs almost always appear before it occurs or has advanced, such as:
- The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision.
- Flashes of light in one or both eyes (photopsia)
- Blurred vision.
- Gradually reduced side (peripheral) vision.
If a retinal tear has nicked a blood vessel, people might red, pink, or dark-coloured spots floating in their vision. Often times between 50 and 70 years of age, the vitreous jelly membrane will peel away from the retina, and cause no damage to the retina. This is called a posterior vitreous detachment.
Stress impacts us mentally and physically, but did you know it can affect our vision? When we are severely stressed and anxious, high levels of adrenaline in the body can cause pressure on the eyes, resulting in blurred vision. People with long-term anxiety can suffer from eye strain during the day on a regular basis.
