To find the number of pupils who do not wear spectacles, we subtract the number of pupils who wear spectacles from the total number of pupils in the school.
Total number of pupils in the school: 2250
Number of pupils who wear spectacles: 2/5 * 2250 = 900
Number of pupils who do not wear spectacles: 2250 - 900 = <<2250-900=1350>>1350
Therefore, 1350 pupils do not wear spectacles.
