School Health Program: Facilities: 40 students per class should have 1 latrine/toilet. 60 students should have 1 urinal. 25% of the area in the classroom should have doors and windows. Yoga Training: 2 teachers and 2 students will be selected for training in Yoga. Teacher Training: 1-day training for teachers to screen children for refractive errors (screening done using Snellen’s chart). Maximum of 150 students can be screened and provided with care and food. Visual Acuity Check: If visual acuity is less than 6/9, the child should be referred to a higher center. The school health program includes screening for refractive errors by teachers and comes under the Primary Health Center (PHC) vision center. National Program for Prevention of Blindness and Visual Impairment (NPCB & VI): Most common refractive error is visual acuity less than 6/9. Blindness is defined by WHO and NPCB & VI as visual acuity of less than 3/60 in the better eye, or in individuals who cannot count fingers at 3 meters distance even with the best possible correction. NPCB & VI Classification: Low vision: Less than 6/18. Economic blindness: Less than 6/60. Social blindness: Less than 3/60. Manifest blindness: Less than 1/60 but with perception of light present. Absolute blindness: No perception of light. WHO Classification: Mild to low vision: Less than 6/12. Moderate to severe blindness: Overlaps with NPCB & VI classification, particularly in social and manifest blindness.
