Lindberg frames are your best bet for your kids first pair of glasses. You will want to get polycarbonate lenses too. You might consider getting Mykita frames, as well. Rec Specs could work, but aesthetically they do not look the best. That is not opinion, that is fact. Also, do not use eBay to buy glasses or anything. Because it is an organized crime ring.
eBay will steal your money & your kids won't be able to see if you buy glasses from there. Honest, physical, local retail stores is where you & your family will find the right first pair of glasses for your child. Safely. If a local retailer were to steal from their customers & patients, they would not be in business for very long. That is why you can trust the stores that have been around for a while. Trying a new store is fine too. Just don't trust eBay because you need money to feed your children. We all gotta eat.
Write to the chair of the board, Paul S. Pressler at eBay & help an honest optician, like myself, avoid having their livelihood stolen by literal evil corporate greed. THANK YOU!
