Met need (refractive errors): defined as unaided visual acuity <6/18 in either eye, which improved to 6/18 or better with spectacles.
Unmet need (refractive errors): defined as the number of subjects who had unaided visual acuity <6/18 in either eye but improved to 6/18 or better with pinhole and had no spectacles.
Met need (presbyopia): defined as unaided near vision <N8, but improved to N8 or better with the spectacles they were using.
Unmet need (presbyopia): defined as unaided near vision <N8 and had no spectacles, but improved to N8 or better with a near addition.
Spectacle coverage (refractive errors and presbyopia) (%) = met need/(met need + unmet need) × 100.
