No, one cannot survive by dozing off. While taking short naps or dozing off for a few minutes can provide some rest and rejuvenation, it is not a sustainable way to survive. The body needs proper sleep, nutrition, and hydration to function properly and maintain overall health. Consistently relying on dozing off as a primary means of rest will ultimately lead to physical and mental exhaustion, and can have negative effects on overall well-being. **

After dozing in the sun, you may see a blue tint because of a phenomenon called photokeratitis, also known as snow blindness. This occurs when the cornea is temporarily damaged by UV rays, causing a temporary blue tint in your vision. The blue tint is a result of the cornea's response to the UV radiation, and it should fade as your eyes recover. It's important to protect your eyes from excessive sun exposure to prevent this temporary vision disturbance. **
