英《新科学家》第86卷第1204期(1980年)报道:新生婴儿通常不能正确地对人正视,常集中视力于其鼻部前方,直到6个月龄时,才受到适当的控制。剑桥大学的阿特金森(JanetteAtkinson)、豪兰(Howard Howland)等3人用简单的光折射新技术证明,甚至9日龄的婴儿也能对距离不等的目标注视,只是无坚持和精确能力。另外,在不满一岁的许多婴儿中,对各种方向并不能都很好地注视(散光)。阿 The New Scientist, Vol. 86, No. 1204 (1980) reports that newborn babies often do not properly face up to their eyes and often focus their eyesight in front of their nose until they are properly controlled at 6 months of age. Three people, including Janette Atkinson and Howard Howland of the University of Cambridge, have demonstrated with simple light-refraction techniques that even 9-day-old infants can gaze at targets that range in distance, with no perseverance and precision . In addition, many babies under one year of age do not look well (astigmatism) in all directions. Ah
