What is a recommended treatment principle for snowblindness?

For the treatment of snowblindness, warm compresses over the eyes is considered a recommended treatment principle. Snowblindness, or photokeratitis, occurs due to overexposure to ultraviolet (UV) light, which can lead to inflammation and discomfort in the cornea. Warm compresses help soothe the irritated eyes, promote comfort, and may aid in the healing process by improving blood flow to the affected area.

Using sunglasses right away, while helpful in preventing further UV exposure and protecting the eyes from bright light, is not a treatment for snowblindness once it occurs. This approach primarily acts as a preventive measure rather than addressing the immediate discomfort caused by the condition. Cold compresses could potentially exacerbate discomfort since cold can increase sensitivity in irritated eyes. Finally, applying topical anesthetics generally is not advisable for treating this condition, as they may mask pain without addressing the underlying inflammation and could lead to further damage or complications.

In summary, warm compresses provide the appropriate soothing relief necessary to help manage the effects of snowblindness effectively.
