Eye flashes are unexplained brief flashes of lights seen in one or both eyes. They often occur on the edges of vision and they are fairly common. Each flash, which can vary from a bright light to almost a sparkle, lasts a varying length of time. Periods of flashing can go on for several months. The symptoms are often most noticeable when going from...
Eye flashes are most commonly due to age-related changes in the vitreous humour. The vitreous humour is the jelly-like substance which fills the inside of the eye, between the lens and the retina. The vitreous humour is contained in a fine membrane and this is attached to the retina at the back and the lens at the front.
Most eye flashes are caused by changes in the vitreous humour which are related to age and which are harmless. Occasionally flashes can be a sign that the retina is at risk of being torn or detached. Increasing, persistent or constant flashes all suggest strong pulling on the retina and may mean that you are at risk of retinal damage. Flashes accom...
Floaters are shapes (opacities) floating in the field of vision. They may look like spots, threads, spiders or cobwebs. They move as you move your eye and can seem to dart away when you try to look at them. They drift about inside the eye rather than staying still. They tend to be more obvious when bright objects, such as a blue sky, are being view...
Floaters are usually not serious. However, you should see your doctor or optician, or visit the A&E department, if any of the following apply: 1. They come on suddenly. 2. There are large quantities of them. 3. They are particularly disturbing. 4. They are associated with other eye symptoms such as pain, severe headaches, changes in your vision, gr...
Haloes are rainbow-like coloured rings around lights or bright objects. They usually occur because there is extra water in the layers of the eye. The most common and important cause of this is acute glaucoma. If you have glaucoma, you have increased pressure in your eye. This is a very painful condition which can threaten your sight if not treated ...
Because haloes can be a sign of increased pressure in your eye (glaucoma) then it is important you see your doctor or optician if you develop persistent haloes. It is also important that you do not drive in conditions where haloes may be affecting your vision - for example, when driving at night. If you have any doubts about your fitness to drive i...
Most people will notice occasional floaters, as there are often small opacities and crystals in the vitreous. Because more marked floaters, together with eye flashes and haloes, are mostly caused by conditions occurring naturally in older eyes, most people who experience them are over 60 years of age, although occasional floaters are not uncommon i...
You should seek urgent advice about eye floaters and flashes if they are very marked or sudden in onset. You should also seek urgent advice if they are associated with pain, or changes in your vision, of if both floaters and flashes are occurring together. You should always seek advice if you develop persistent haloes. You should seek advice for an...

Causes. Haloes, glare, and starbursts occur due to light scattering in your eye. This can be caused by changes in the cornea, lens, vitreous, or retina. Pupil size is also important: people with large pupils experience more haloes and glare than those with small pupils.
