Having an eye examination at least once every two years should be part of everyone’s health care routine. Many causes of sight loss are preventable if they are caught early by visiting an optometrist.
However, if you have a diagnosed eye condition it would be wise to have a sight test every twelve months. This also applies if you have diabetes, you should usually be invited for annual screening by the health service as it is very important that your vision is monitored.
Anyone with a family history of glaucoma and over the age of 40 should have annual checks which most importantly includes a test for the pressure in the eye. As glaucoma classically affects the field vision first, major irreparable damage can be done before someone notices.
