Internal-reading manual lensmeter with ±25 D range and 20Δ compensation prism. Mid-tier sibling of the LM-6 for opticals that prefer eyepiece-only readout.
Clinical overview
The LM-7 is the internal-reading variant of the LM series. The scale reads inside the eyepiece — operators who came up on classic Marco / Topcon-style lensmeters will find it familiar in a single look.

The mire target is crisp and the sphere, cylinder and axis wheels move with a positive, well-damped feel that makes neutralising a lens quick and precise. Prism measurement and marking are equally reliable.
