Certificate of Visual Impairment (CVI)
The Certificate of Vision Impairment (CVI) form is for use by the patient or representative, consultant ophthalmologist and hospital eye clinic staff. It formally certifies someone as visually impaired, and also acts as a referral for a social care assessment if the individual is not yet known to social services.
If your vision has deteriorated to a certain level, you may choose to register as visually impaired. Depending on the severity of your vision loss you’ll either be registered as sight impaired (previously “partially sighted”) or severely sight impaired (previously “blind”).
Your eye specialist (ophthalmologist) will measure your visual acuity (ability to see detail at a distance) and your field of vision (how much you can see from the side of your eye when looking straight ahead).
These measurements will help your ophthalmologist determine whether you’re eligible to be certified as sight impaired or severely sight impaired. If you are, they will complete an official certificate with the results of your eye examination.
In England and Wales this certificate is called the Certificate of Vision Impairment (CVI)
Your ophthalmologist will send a copy of the certificate to you, a copy to your GP and a copy to your local social services department. Upon receiving the certificate, your local social services team will contact you to ask whether you want to be added to its register of visually impaired people. For the borough of Merton this is held by MertonVision.
Registering isn’t compulsory but it can entitle you to a range of benefits, including:
