Read previewIt's not safe to look at a solar eclipse without wearing certified protective glasses. Some people might start to notice vision changes within a few hours, though it's most likely they would become apparent by the next day, according to the American Academy of Ophthalmology. Unlike sunglasses, eclipse glasses are so dark that you shouldn't be able to see through them, he said in a statement. If you are experiencing vision changes or eye pain, even if you wore proper eye protection, call an eye doctor to schedule an appointment. A 4-year-old uses special glasses to look into the sky during a partial solar eclipse in Berlin.

☆ The white-gold, black-blue dress controversy raised scientific questions about visual perception, but the way our eyes and brains work explain the illusion

Depending on whom you ask, this dress might be black and blue or white and gold. Some people saw a blue and black dress, while others saw a white and gold dress. It makes the blue part look white and the black part look gold. In other words, our individual sensitivity to the blue background lighting of the photo is changing how we see the object in the image. The blue bars are the same at the top, bottom, and middle but appear to change color (look darker) as your eyes move down the figure.
