'Even people with normal vision can develop it if they are blindfolded,' he says. Do you notice them more when you look at something bright like the sky or a white sheet of paper? This is where you don't produce enough tears or the tear film evaporates too quickly, causing the eyes to dry out and become inflamed. 'This can be a symptom of multiple sclerosis, but is rare, so speak to a specialist before panicking,' says Mr Berghardt.

'Dry eye syndrome is increasingly common thanks to the increasing use of air conditioning and computer screens.'. TREATMENT: Floaters are harmless, but if they start to have a real impact on sight, they can be rectified with a vitrectomy. In rare cases, fogginess can be caused by a brain tumour pressing against the back of the eye, or optic neuritis - inflammation of the optic nerve. SYMPTOM: Like looking through a kaleidoscope with zig-zaggy lines. These form part of the vitreous jelly which maintain the eye's shape, but they can pull free from the edge of the jelly and float harmlessly across the field of vision. This happens every time I wake throughout the night. A persistent fogginess is more likely to be a cataract, which is when the lens of the eye becomes cloudy - again this is more commonly seen in those over 50. Kaleidoscope vision: This could be a warning of a migraine. But when people start losing their sight - most commonly due to age- related macular degeneration or sometimes glaucoma - their brains don't receive as many pictures and new fantasy pictures or old pictures stored in our brains are released and experienced as real objects.

Moving your eyes up and down is usually more effective that shifting them from side to side. This is caused when the photosensitive cells on the retina are temporarily bleached and take a few seconds to adapt. 'The brain starts to build artificial images from the areas we use every day to process faces, objects, landscapes and colours.'.
