Children's glasses

Glasses are becoming ridiculously expensive- but my kids buy theirs on-line.

The lenses you mention are specifically for myopia.
They are probably worth the money.

Our son wore glasses from age 4 as he was a prem baby, now at 30, he no longer needs glasses.

Here’s a link explaining the technology behind these lenses.

Depending on the age of your granddaughter, it's rather a foolish suggestion from that salesperson. Children grow and the glasses will need replaced. They can also break glasses more easily just by being children. I wouldn't spend that on them either.

I ve never heard of special lenses to slow down shortsightedness I d do some research about that before shelling out or saving up I have three out of seven grandkids
( cousins) all wear contacts one very far sighted although every glasses wearer in the family have been shortsighted except this one
