Some eyepieces with a metal eye-stop will scratch ones spectacles while trying to observe the entire field: big problem!
The Delos design is a compromise between an eyepiece with a super wide field and a narrower field eyepiece with a large eye relief.

Over the years, the number of eyepieces compatible with glasses has steadily grown. Tele Vue is one company with significant numbers of offerings for the glasses wearer (Delos, Delite, Nagler T7, etc.) but other companies have addressed the issue too: Baader, Pentax, and many private label brands for the manufacturers KUO, Barsta, JOC and Synta.
If you'd like to see all the possible choices, download the 2025 Eyepieces Buyers Guide and look for eye reliefs of 18mm or more.

It's a fairly long thread.
