Hi Saqib,

At those powers, they are more likely to be microscope
objectives. Did the have an external screw thread one end?. They
are optimised to look at an object 45mm from the flange near the
screw thread and produce an image at about 150mm to 170mm from
the flange on the opposite side.

No good as eyepieces at all.
