Sight Classification
Sight classification is a system used across VI sport to ensure fair, equal, and inclusive competition. It helps organisers understand an athlete’s level of vision so that everyone competes on a level playing field.
What is Sight Classification?
Sight classification is based on two key factors:
- Visual acuity — how clearly you see straight ahead
- Visual field — how wide your peripheral vision is
After an assessment, athletes receive a Sight Classification Certificate, which can be used when entering competitions.
Why Classification Matters
Classification ensures:
- Fair competition
- Equal opportunity
- Clear pathways into sport
- Consistency across clubs and competitions
- Inclusion for athletes with all levels of vision
It also helps coaches understand how best to support each athlete.
Classification Categories (B1-B5)
Sight classifications range from B1 to B5, with B1 representing the greatest level of sight loss.
Most VI sports including Showdown use B1, B2, and B3 for competition.
Classification is based on an athlete’s best corrected vision, meaning:
- The better eye is used for assessment
- Vision is measured with glasses or lenses (even if not worn during sport)
Category Breakdown
B1
- No light perception, or
- Some light perception but unable to recognise shapes
B2
- Significantly limited vision
- May be able to count fingers or read at very short distances
- May have a severely reduced visual field
B3
- Limited visual acuity and/or restricted visual field
- Highest category used in most international and Paralympic sports
B4 and B5 exist but are not typically used in VI sport competition pathways.
