�Do you know how well your kids can see? Are you sure?"

"I�m a mother of three with access to top pediatricians and a network of neurotic moms, yet I was never advised to get my children�s eyes checked. Last summer I took my 4-year-old to an optometrist with an air of confidence that I was just being overprotective. Much to my sickening surprise, he could barely see, as it turns out. One of his eyes was giving up, a nonreversible condition if not caught early. My son�s eyes lit up when glasses were put on and he could see properly. (Insert mom guilt.) His whole demeanor changed; he would cry, scream and nap a lot until that point. We had taken him to many specialists, and no one had suggested that we get his eyes checked...."

A letter to the editor of the NYT in response to an op-ed titled "Kids Who Can�t See Can�t Learn." The op-ed, by an ophthalmologist, stressed the need for getting free vision screening and free glasses to less affluent children. The letter writer's point is that even where there is excellent access to health care, a child's vision may go uncorrected for too long. I wonder how many specific health problems in children go untreated because we expect random misbehavior and orneriness from them.

"But for the past half-day, people across social media have been arguing about whether a picture depicts a perfectly nice bodycon dress as blue with black lace fringe or white with gold lace fringe."

"And neither side will budge. This fight is about more than just social media�it�s about primal biology and the way human eyes and brains have evolved to see color in a sunlit world."
