我记得早上起来会看到眼前有黑色网络，但是一会儿就不见了，大概是下面这个模样

或者大概是这样：

根据\[1\]

**问题分析：**早上睡醒睁眼时眼前出现暗蓝黑色网状现在并且持续时间比较短，可能是因为视网膜产生异常生物电导致的放电现象，睡眠时姿势不对如俯卧压迫眼球及存在熬夜睡眠不足和用眼过度的情况下，都可能刺激眼底视网膜产生生物电。  
**意见建议：**建议到医院眼科检查下眼底视网膜，进行眼底镜检查是否存在有视网膜剥离或玻璃体膜后脱离的情况，平常注意眼睛的休息。

根据\[11\]这种现象是purkinje tree现象，详细的描述见\[12\]

The Purkinje tree is an image of the retinal blood vessels in one's own eye, first described by Purkyně in 1823.\[10\] It can be seen by shining the beam of a small bright light through the pupil from the periphery of a subject's vision.

Purkinje tree就是视网膜血管

Unless the light moves, the image disappears within a second or so. If the light is moved at about 1 Hz, adaptation is defeated, and a clear image can be seen indefinitely. The vascular figure is often seen by patients during an ophthalmic examination when the examiner is using an ophthalmoscope\[12\]

此类现象和眼睛适应光线的频率相关，以及在眼科检查中也能看到这类现象。

根据\[13\]也可以称为： angioscotoma(血管暗点现象)

总的来说，早上看到黑网，不用担心这个问题。
