Redview

Introduction Red Vision: The negative acceleration is opposite to the positive acceleration. The inertial force pushes the blood from the foot to the head, causing the head to form high blood pressure. The pilot will feel wearing a pair of red glasses, and the surrounding world will become a red world. After the aircraft is changed, the pilot's brain will still feel stinging, his face will swell and he will not open. The negative acceleration is opposite to the positive acceleration, which pushes the blood from the foot to the head, causing the head to form high blood pressure. The pilot will feel like wearing a pair of red glasses, and it will become a red world. After the plane is changed, the pilot will still feel stinging, his face will swell and he will not open his eyes. In the negative 3G, some people may have red-eye phenomenon. When the negative 4G, the head blue muscles will burst, and one thing will become two, and even nothing can be seen.

Cause

When the load is too high, red vision is generated, starting with an acceleration of about 2G.

The negative acceleration is opposite to the positive acceleration, which pushes the blood from the foot to the head, causing the head to form high blood pressure. The pilot will feel like wearing a pair of red glasses, and it will become a red world. After the plane is changed, the pilot will still feel stinging, his face will swell and he will not open his eyes. In the negative 3G, some people may have red-eye phenomenon. When the negative 4G, the head blue muscles will burst, and one thing will become two, and even nothing can be seen. When the negative 4.5G, the spirit may be confused, even coma, ordinary people can only endure negative 3G5 seconds, the greater the difference between the head and the heart level, the more uncomfortable the person, the more likely it is red-eye, the red-eye is more dangerous than the black-eye However, the violent negative acceleration in flight is relatively low, so red vision is rare.

Differential diagnosis

Differential diagnosis of red vision:

1, black eye: is a physiological phenomenon, caused by head ischemia, so most black eyes phenomenon occurs in the case of overweight. The most serious point.

2, blue and yellow weak: the difference in color discrimination is called weak color, and its boundary with color blindness is generally not easy to distinguish strictly, but the degree of severity is different. Color weakness includes weak color and partial color weakness (red weak, green weak, blue-yellow weak, etc.). Blue and yellow are also known as the third color blind. The patient's blue-yellow color is unclear and is identifiable to red and green. Blue and yellow are a type of color blindness. 3, blue and yellow blind: blue and yellow blind, also known as the third color blind. The patient's blue-yellow color is unclear and is identifiable to red and green. People with blue-yellow color blindness are difficult to recognize blue and yellow. Blue-yellow blindness includes blue blind (tritanopia, third color blindness) and blue weak (tritanomaly, third color weak). Blue-yellow blindness is one of color blindness.

4, yellow vision: yellow vision refers to the apparent yellowing of the object, accompanied by blindness (lower visual acuity in the context of increased illumination), blurred vision, reduced color vision and side dark spots.

5, green vision: green vision because the brain is often affected by some direct stimulation or lesions. The negative acceleration is opposite to the positive acceleration, which pushes the blood from the foot to the head, causing the head to form high blood pressure. The pilot will feel like wearing a pair of red glasses, and it will become a red world. After the plane is changed, the pilot will still feel stinging, his face will swell and he will not open his eyes. In the negative 3G, some people may have red-eye phenomenon. When the negative 4G, the head blue muscles will burst, and one thing will become two, and even nothing can be seen. When the negative 4.5G, the spirit may be confused, even coma, ordinary people can only endure negative 3G5 seconds, the greater the difference between the head and the heart level, the more uncomfortable the person, the more likely it is red-eye, the red-eye is more dangerous than the black-eye However, the violent negative acceleration in flight is relatively low, so red vision is rare.
