I never write reviews but felt I needed to review the two items I recently purchased. My 10 year old son loves his iPad and computer but also suffers with terrible migraines, although we limit his screen time I can honestly say that since wearing the Block blue light glasses his migraines have definitely improved, he loves the style of the glasses and they are also very comfortable to wear which is an added bonus. I also purchased a bed side light as he always sleeps with the light on, it gives a lovely warm glow which definitely aids his sleep. I highly recommended these products and most of my friends are looking into purchasing the glasses for their computer mad kids too. As technology continues to improve its inevitable that kids will be spending more and more hours glued to their gadgets so for me purchasing relatively inexpensive items to improve their well-being is a no-brainer to me! Thank you Block blue light keep up the good work your amazing!
