Quick Answer
Snow blindness, also known as photokeratitis, is a serious condition that requires immediate first aid. Critical steps include seeking shade, applying ocular lubricants, and resting eyes. Administering pain relief may also be necessary.
Understanding Snow Blindness
Snow blindness is caused by prolonged exposure to snow glare and UV radiation. It can occur even on overcast days when snow reflects sunlight, making it essential to take precautions. If symptoms appear, seek shade immediately to prevent further damage.
First Aid for Snow Blindness
Apply a small amount of lubricating eye drops or ointment, such as petrolatum or carboxymethylcellulose, to help soothe the eyes and promote healing. Wear sunglasses or goggles with UV protection to prevent further irritation. If pain persists, take over-the-counter pain relievers like ibuprofen or acetaminophen, following the recommended dosage. For severe cases, consult a medical professional for further guidance.
Advanced Care and Prevention
When returning indoors, flush the eyes with sterile saline solution to remove any debris or irritants. Rest the eyes for at least 24 hours to allow them to recover fully. To prevent snow blindness, wear protective eyewear with UV protection when spending extended periods outdoors in snowy environments. A good rule of thumb is to wear protective eyewear with UV 400 protection, which blocks 99% of UVA and UVB radiation.
