The growing popularity of eyelash extensions has led optometrists to issue warnings about "eyelash lice".
Health experts are finding people with eyelash extensions can have mites crawling around their eyes and optometrists say they are seeing more such cases.
The medical term for the condition is Demodex.
Because the issue is not widely known, experts say people who wear eyelash extensions do not clean them enough.
That lack of cleaning the strands can lead to an increase in bacteria, which can even lead to infections.
