@drsermedmezher: “Stare at the Sun” #wait. Sources- PMID 37428439 buddhaboolin on TT The human eye’s efficient design becomes a massive liability when looking directly at the sun. Your cornea and lens act like a powerful magnifying glass, taking the intense energy of solar radiation and focusing it down into a tiny, hyper-concentrated point on your retina. Just like using a magnifying glass to burn a hole in a leaf, this beam rapidly cooks the delicate tissue at the back of your eye, causing severe thermal and photochemical damage known as solar retinopathy. The most dangerous aspect is that your retina completely lacks pain receptors, so you can burn away your vision without feeling any physical discomfort. As the concentrated light destroys your photoreceptor cells, a permanent blind spot forms in the center of your vision. Because this cellular damage cannot heal, even a brief stare can cause lifelong, irreversible sight loss. #sungazing #sun #health
