FULL RIM

Hold the upper and lower rims of the support lens in one hand. With your other hand, unhook the thinner lower frame wire by pressing it together out of the jaws.

Remove the support lens.
Gently break the edge of the groove where the wire runs using a file.

Lastly, insert the lens.
With the lower rim placed in the groove, gently hook it back in using the jaws –and done!
Bracket can be shortened.
