Get an urgent opticians appointment
You can get your eyes checked at an opticians.
Call an opticians near you and ask if you can have an urgent appointment.
Your eyes will be checked to see if you might need to be seen by an eye doctor (ophthalmologist) for more tests or treatment.
You'll usually only need treatment if you have a problem that could affect your vision.
Lots of people, particularly older people, get floaters and flashes.
They're usually caused by a harmless process called posterior vitreous detachment (PVD), where the gel inside your eyes changes.
Sometimes they can be caused by retinal detachment.
This is serious and can lead to permanent vision loss if not treated.
Floaters and flashes can also happen for no obvious reason.
