What is the final view seen in the radiuscope before reading the scale?

The final view seen in the radiuscope before reading the scale is the spoke pattern. This pattern is essential in providing a clear indication of the curvature of the lens being measured. The spoke pattern is created by the interaction of light with the surface of the contact lens, and it provides a visual reference that allows the practitioner to take accurate measurements of the lens features.

After observing the spoke pattern, the practitioner is positioned to assess the curvature radius more effectively. This final view helps to ensure that there is no ambiguity in the measurement process, making it a critical step before recording the data on the scale. The spoke pattern acts as a distinct visual cue that confirms proper alignment and focus when taking measurements in the radiuscope, ensuring the practitioner is prepared for accurate readings.
