What happens if you look at the fire for a long time?

Looking at a fire for a long time can be dangerous for your eyes. The bright light of the fire can cause damage to the cells in the eye, leading to a condition called photokeratitis or "snow blindness". This is a temporary condition that can cause extreme pain, redness, and blurred vision. Over time, prolonged exposure to the fire can cause permanent damage to the eyes, including macular degeneration, cataracts, and retinal burns. In extreme cases, it can even lead to blindness.

Therefore, it is important to take precautions when looking at a fire for a long time. Always look away periodically, and wear sunglasses or protective eyewear if possible. If you experience any pain or discomfort in your eyes after looking at the fire, seek medical attention as soon as possible.
