Clinical overview
Product overview
The OpticsMED CM-1900C is the standard-configuration sibling of the CM-1900P — same 23" LCD chart monitor, same chart library, same working-distance range, but without the polarised-chart support that the P-variant adds for binocular tests. The right pick for general optometry rooms running standard monocular and binocular acuity testing without dedicated Worth-four-dot or stereo test workflow.

Bought this for the practice and setup was straightforward with clear documentation. The finish is clean and professional. Solid purchase overall.
Dr. Thomas White, OphthalmologistVerified buyerJul 15, 2025
Acceptable quality
This has quickly earned its place in our practice — it's stayed accurate and reliable throughout. It does the job but doesn't feel premium. Worth it on balance, with the caveats above.
