Review on 👶 Kids' Blue Light Glasses for Toddlers: Reduce Eye Strain, UV Glare & Fatigue from Digital Screens. Nerd Square Baby Glasses (Age 1-4) - Black-Red, 115mm by Bob Candfield

They really work I bought them for my niece, she's about a year and a half so I took the 121mm size. It fits tiny a little big but she will grow into it very soon. The blue light it is equipped with is a tester. If you shine blue light into your eyes, it hurts, but if you put on glasses and then shine blue light, it doesn't hurt your eyes. It also comes with a cloth and a small pocket for your glasses. I really think everyone who has a child should buy them. I don't have the product with me as I gave it to my niece but if I did I would post a photo. However, the photos provided by Revain are very accurate in what you expect from your order.
