What is a Certificate of Vision Impairment (CVI)?

A Certificate of Vision Impairment (CVI) formally certifies that someone has sight loss. It also acts as a referral for a social care assessment if you are not yet known to social services.

Getting certified

Once you've been referred to a hospital eye clinic, an ophthalmologist will carry out an assessment to measure how good you are at seeing detail at a distance (your visual acuity) and how much you can see from the side of your eye when you're looking straight ahead (your field of vision).

They will then decide if you are eligible for your sight loss to be certified. Depending on the results of these tests, the consultant will complete a Certificate of Vision Impairment (CVI) to certify you as either severely sight impaired (blind) or sight impaired (partially sighted).

When the Ophthalmologist (eye doctor) signs the form, they are certifying that you are eligible to be registered with your council. You will also be asked to sign the form. They may tell you that they are registering you; however they are only completing the CVI, which is only the first stage of the registration process.
