DOUBLETAKEReading Glasses - 2 Pairs Compact Case Included Semi Rimless Readers

What is a frame front width?

Will glass cleaner ruin the lenses?

Are those lenses of glass or plastic?

I have ordered several pairs in the 1.0x strength, but they appear to only be in stock from 1.75x to 4.0x. Will you be getting more at the 1.0x?
