Floaters, spots, or ‘cobwebs’ are small specks or strands that move through your field of vision. They are often most visible when looking at a lighter background such as a lightly coloured wall, piece of white paper, a bright sky or a white computer/tablet screen.
Floaters can be caused by many things:
Some people experience flashes of light that appear as jagged lines or “heat waves” in both eyes, often lasting 10-20 minutes. These types of flashes are usually caused by a spasm of blood vessels in the brain, which is called a migraine.
While annoying, ordinary eye floaters and spots are very common and usually aren’t cause for alarm. However, in about 5% of cases with a PVD a tear in the retina is discovered, showing the need for regular examinations.
If you notice a sudden appearance of increased floaters and/or flashing lights in your eye, you should arrange to see us at Optika Opticians immediately. We will perform a detailed examination of the retina after inserting dilating drops, you will not be able to drive for at least a few hours after the examination. As your pupil(s) will be dilated it may appear quite bright outside, so on a sunny day it would be wise to bring sunglasses with you. The examination could indicate a retinal tear, a retinal detachment, or another eye problem has occurred that could be a vision-threatening condition.
If we feel that it is necessary we will arrange for you to be seen in the Eye Department at the nearest Eye Hospital for further examination.
