The Nagler Type 7 series was developed as a natural extension of our highly regarded, 85°, limited edition Apollo 11 eyepiece. However, the series can also be thought of as an extension of the long eye relief Nagler Type 4 concept. With the all-new Type 7 design layout, we achieved our goal of Apollo 11-like performance across a series of focal lengths that are eyeglass friendly.
