谢谢分享。看了一下,0-18months的话,孩子还是能看清一些东西的。

新生儿视力和成人不一样的。。新生儿只能看清近距离的东西。所以这种设计透明的新生儿远了根本看不到的,个人认为给家长的噱头而已。逐渐长大视力范围才会靠近成人一样。

What Can My Baby See?
Your baby sees things best from 8 to 12 inches away. This is the perfect distance for gazing up into the eyes of mom or dad (a favorite thing to do!). Any farther than that, and newborns see mostly blurry shapes because they're nearsighted. At birth, a newborn's eyesight is between 20/200 and 20/400.
Their eyes are sensitive to bright light, so they're more likely to open their eyes in low light. Don't worry if your baby's eyes sometimes cross or drift outward (go "wall-eyed"). This is normal until your baby's vision improves and eye muscles strengthen.
Give your baby lots of appealing things to look at. After human faces, bright colors, contrasting patterns, and movement are the things newborns like to look at most. Black-and-white pictures or toys will keep your baby's interest longer than objects or pictures with lots of similar colors.
When quiet and alert, your baby should be able to follow the slow movement of your face or an object. |
