The optical isolation is accomplished within the confines of a single component on the board. There is no risk of getting something opaque in the way unless they break open that chip.
If you do break a victor open and take a look, it is the tall-ish 4 or 6 pin* device near the connector.
* (I can't remember: Only 4 pins are used, but often these devices are in a 6-er to match the 5-pin devices in the family.)
