Bought these for my small 8 year old ( 48 lb)s. His eyes fatigue after reading.. he is a great rewarded already. We homeschool and despite noticing eye rubbing, headaches and fatigue at the end of the school day, every time the pediatrician tests his eyes they say he has 20/20 vision and won’t refer for eye exam… so, remembering I had astigmatism as a child, I tried readers.. mine and my husband’s mild ones… worked, but too big.. these fit perfect and help him read whatever time of day, or despite fatigue. Love these!!! They come with a case, cord to keep from falling off, ( but long)so I wouldn’t give to a toddler, and microfiber cloth.ReadingI really like them fit great.
