A couple thoughts about the recent, comprehensive post(9/26) to my Facebook page about blurry vision. Hyperopia in children is often missed because children can, with effort, compensate for significant hyperopia(farsightedness). They won’t report blurry vision but their eyes fatigue and if eyestrain is too burdensome they may avoid reading!
The absence of blurry vision doesn’t mean there is nothing wrong with your vision. Cardiovascular problems can be detected in asymptomatic patients during routine eye exams
