However, in spite of a fairly mature glass industry, there is no mention of any type of lenses in the WGW. No eyeglasses or magnifying glass of any sort. Glassforge can produce large quantities of window glass, enough to transport it across the half-continent available to them. They make decorative glass bowls. I don’t understand why no lenses.

It can be odd when a society appears to miss an easy technology.    Sometimes the technology appears to be simple, such as stirrups or horse collars (both of which have had major impacts).

I imagine there are simple philosophies that we also miss.
