As people age, their vision tends to deteriorate, and one expert has said that they could experience "floaters" in their eyes.
Writing on the Daily Mail website, Dr Martin Scurr explained that older adults may see shapes floating in front of their eyes - but people with this condition should be assured that their sight is not in danger.
Around 75 per cent of people over the age of 65 develop this condition, he noted, as the vitreous humour pulls away from the back of the eyeball.
The retina, which sends images to the brain, is covered in a layer of light-sensitive cells, and when this detachment happens, people will experience symptoms.
These "floaters" are caused by strands floating across the vision, and flashes of light can also be caused by any remaining strands tugging on the retina.
People with the condition will be pleased to hear that generally the symptoms fade with time, but there is no treatment that can help speed up this process.
