I've had them for about a decade since around time of final period. Fully checked out after Optician referred me to Ophthalmology & later at A&E after a big increase in number of floaters I'd been warned to flag up. At first just one floater but quite quickly more & more appeared & I now have many in each eye. The flashes began around same time as first floater but gradually reduced to virtually nil after I started HRT. When reducing dose or tapering off, the flashes tend to come back. Floaters have not improved for HRT, though I really hoped they would! Very noticeable in bright conditions, against light walls & ceilings, some grey specks, some longer strands like thin fibres. Last Ophthalmologist said he could see them on examination.
