Actress Busy Philipps accidentally sunburned her eyes and had to go to the ER. She told fans about it on Instagram to warn them. She wrote, "I can barely see straight. I can't open my eyes. It feels like there's shards of glass." The condition she had is called photokeratitis that occurs when eyes are overexposed to UV rays. It can be prevented by wearing eye protectants while in the sun or near bright bulbs.
