It is generally recommended that you have your eyes tested by an
optician once every 2 years, unless you already have a diagnosed eye
condition in which case it is sensible to have them tested every 12
months or as advised by your optician.
It is not just adults who should have their eyes tested. It is important
that children have their eyes examined regularly, and we are pleased to
be able to provide this service.
This information is provided by the US National Institute of Health's National Eye Institute.
