Yes! Common conditions such as amblyopia (lazy eye), convergence insufficiency (eye teaming problem) or astigmatism can go completely undetected during a screening. Children with these conditions may have no problem reading the 20/20 line and therefore pass the screening. But they often suffer from distortion, blurry vision, and eye fatigue. Since 80% of learning is visual, or through our eyes, it is extremely important for every child to get a full comprehensive eye examination.
