How bad does your visual impairment need to be to be registered as a blind or partially sighted person?
Your eye specialist (a consultant ophthalmologist) will decide if you can be certified as severely sight impaired (blind) or sight impaired (partially sighted).
will decide whether you meet the criteria for certification by measuring your:
- Visual acuity – your central vision, the vision you use to see detail.
- Visual field – how much you can see around the edge of your vision, while looking straight ahead.
Your visual acuity is measured by reading down an eye chart while wearing any glasses or contact lenses that you may need, so remember to bring them to your appointment. The test for visual acuity is known as a Snellen test. Your field of vision is measured by a “visual field test”. There are guidelines about the level of sight needed to be registered severely sight impaired (blind) or sight impaired (partially sighted).
