Diffuse superficial keratitis

...When exposed to large amounts of ultraviolet light during skiing or mountain climbing in snowy weather, the condition usually develops after a 6-10 hour latent period, followed by sudden symptoms such as photophobia (sensitivity to light), tearing, foreign body sensation, and eye pain. It is called "snow blindness" or colloquially "snow blindness." It is caused by ultraviolet light reflected from the snow surface attacking the conjunctiva and cornea, and in addition to the above subjective symptoms, there is severe swelling and congestion of the bulbar conjunctiva, and diffuse superficial keratitis. As for treatment, if you avoid ultraviolet light and keep your eyes at rest, the condition will heal naturally within a few days.
