A social media storm has erupted with the hashtag "600 degrees of myopia is a critical threshold", sending shivers through the online community and sparking widespread discussion about eye health.
作为分界线的600度
“600度” 一直都被作为高度近视的分界线,在多部眼科指南被单独划分列出。
The 600-degree mark is widely recognized in major ophthalmology guidelines as the borderline for high myopia.
A normal eyeball has an axial length of approximately 24 millimeters. As myopia worsens, the eyeball elongates — much like an overinflated balloon. Once myopia exceeds 600 degrees and the axial length typically reaches or surpasses 26 millimeters, the risk increases significantly for the condition to develop into pathologic myopia, which goes beyond simple blurry vision.
People with high myopia are urged to take extra precautions. Activities such as extreme sports, heavy lifting, or anything that could cause eye trauma should be avoided.
