I keep on seeing flashing lights, should I be concerned?
Answer:
Flashes can occur for a number of reasons - if they appear to be patterned or zigzagged, it might be due to migraine.
However, most flashes occur together with floaters and are usually a result of the gel within the eye rubbing or pulling on the retina.
As with floaters, it's wise to visit your optician if they become more frequent or worsen.
