The study included almost 250 preschoolers and kindergartners with moderate farsightedness and nearly 250 with normal vision.
Researchers tested both groups and found that farsighted children were more likely to have poorer scores on visual attention, visual perception and visual-motor skills, such as eye-hand coordination. These visual skills are foundational skills for comprehension, spelling and writing.
Of great importance is the fact that farsightedness is often missed, especially in visual screening test where the child is reading a distance chart and not a chart held at near range. Second, eye doctors vary in opinion on whether glasses should be prescribed at this young of age. Symptoms of farsightedness include: blur, squinting, headaches, movement of words on a page, eye rubbing or strain, or avoidance of near tasks.
Personally, I often see children with low to moderate hyperopia that see significant improvement in ability and attention when these glasses are prescribed. It is important to look at the binocular system which gives additional information on when is the right time and amount of power for the prescription. Eighty percent of leaning in school is visual, and I am confident that, when indicated, glasses can improve learning.
