Yes, eye strain is one of the inherent risks of using screen technolog! What we recommend is that each parent supervises their child’s time in front of the screen. These products are meant to supplement your child’s playtime--not monopolize it!
Break up screen time with storytime! Get your kids outside as much as possible and schedule play dates with other kids and parents that don’t involve technology. The more natural light your child receives, the more healthy their vision will be. As for our products, there are many child options that only have an LCD screen which has less glare and is more forgiving.
