Good eyes but poor vision: An indistinct world for 1 in 20

5 junio 2015

Extremely poor vision can be caused by strabismus in early childhood or by a displaced optical axis. Amblyopia is caused not by organic damage to the eyes but by the brain incorrectly fitting together the images the eyes provide. As a result, the ability to see an object in sharp focus is severely limited. This occurs in more than one in 20 people, researchers report. The authors’ study analyzed the visual acuity of over 3200 German individuals aged between 35 and 44 years and determined the frequency and causes of amblyopia.
