Abstract
A hands-free filter assembly suitable for use with a loupe light is described. The hands-free filter assembly includes a filter that moves between an in-use position, where it is filtering light from the loupe light, and a non-use position, where it is not filtering light from the loupe light. The filter can be moved between the in-use position and the non-position without manual manipulation.

A filter assembly for use with a loupe light, the filter assembly comprising:
- a filter attachment configured to be coupled to a light end of the loupe light without obstructing the light end of the loupe light;
- a filter having an in-use position in which the filter substantially covers the light end of the loupe light, and a non-use position in which the filter does not cover the light end of the loupe light, the filter defining a filter hole;
- a pin coupled to the filter attachment, the pin being substantially parallel to a longitudinal axis of the filter attachment, the pin being positioned in the filter hole and allowing the filter to rotate freely about the pin between the in-use position and the non-use position, the pin being configured to prevent the filter from separating from the filter attachment;
- and
- a filter stop coupled to the filter attachment, the filter stop configured to maintain the filter in the non-use position;
- wherein a user is able to move the filter between the in-use position and the non-use position without manual manipulation by flicking the user's head.
