香港街售5000毫瓦高危激光笔 1秒可致盲
香港讯 - 香港深水埗鸭寮街及社交媒体平台近日出现5000毫瓦超强功率激光笔违法销售现象，这些设备足以在瞬间造成永久性视力损伤。
Hong Kong News - Recently, 5000mW ultra-high-power laser pens capable of causing instant permanent eye damage have been illegally sold in Apliu Street, Sham Shui Po and on social media platforms.
记者暗访发现，这些激光设备售价最低仅550港币（约252令吉）。经专家测试：
Undercover investigations revealed these dangerous devices being sold for as low as HK$550 (approx. RM252). Expert tests showed:
- 激光温度高达167°C | Laser temperature reaches 167°C
- 可穿透7层黑卡纸+2mm胶板 | Penetrates 7 layers of cardstock + 2mm acrylic
- 能瞬间烤熟五花肉 | Instantly cooks pork belly
眼科专家警告：此类高功率激光笔若直射眼睛，1秒钟即可造成永久失明。目前香港合法销售的激光笔功率应低于20毫瓦，主要用于教学和天文观测。
Ophthalmologists warn: Direct eye exposure to such high-power lasers can cause permanent blindness in just 1 second. Legally sold laser pens in HK should be under 20mW, mainly for educational and astronomical use.
值得注意的是，部分商家竟宣称这些工业级激光设备具有"美容脱痣"功效，存在严重误导消费者的行为。
