A non‐selected group of 411 school children, 7 to 15 years of age, were screened by the school nurses. The screening program included (1) testing of visual acuity by the Snellen chart (with glasses if worn), (2) observing noticeable strabismus, and (3) recording subjective ocular symptoms related to reading. Later the whole series underwent a thorough eye examination performed by the authors including a hyperopia test and the Titmus stereo test. About 15% of the children failed to pass the screening in schools: 10.0% had visual acuity of less than 0.8 in one or both eyes with glasses, in another 1.0% obvious strabismus was observed, and 4.1% complained of ocular symptoms. The same screening procedure at the final examination revealed another 2% of children with decreased vision, most of them slightly myopic. By hyperopia test 37.0% of children with cycloplegic refraction of +2.0 D. or more were discovered; more than half of them failed also at the present screening. 2.2% of those with mild hyperopia (<+2.0 D.) showed positive hyperopia test. By the Titmus test all but one with manifest strabismus were discovered, whereas children with mild amblyopia passed. Defective stereopsis without other abnormalities was found in 11% of the children.
