Oh, I get it. Carrots help us improve our eyesight. Eye charts are used to test our eye sight. If our eyes are good, they'll see everything on the eye chart. If we eat carrots, then our eyes will be good. Money will be saved on glasses and/or contacts. Very clever. Photographer Henry Hargreaves and Food Stylist Nicole Heffron have made this Carrot Eye Chart to help remind us to eat our carrots. Now time for some science: Carrots contain a high amount of Vitamin A. According to AllAboutVision.com, a deficiency in Vitamin A can cause "night blindness" (or is that just the dark?) Other vegetables that are good for your world-peepers include: spinach, romaine lettuce, broccoli, kale and red bell peppers.
