Does the niqab (veil) wearer satisfy the minimal visual field for driving

Visual field testing of subjects wearing a niqab was carried out using the approved (Esterman) test on a Humphrey perimeter to determine if visually normal subjects met the European driving standard. Measurement of aperture dimensions of the niqab when worn was recorded. When wearing the niqab, all subjects achieved a visual field adequate to satisfy UK/European driving standards. A measurement of the limiting aperture size was obtained and a self-test method for niqab wearers was determined.
