The frames I got are springy and fit me fine, I did not need any adjustment.

The medium sized ones fit me the best.

I has Lasik 7 years ago, but my eyes changed. I have the lowest prescription you can get. Basically I use them for driving at night and at the range.

I got sunglasses also, and the darkest gray ones were good.

Remember it is 4.00 shipping per order, not each pair, so if you are going to order, do it all at once.

For $8 you cant beat it.
