Abstract: The present disclosure describes eyewear hearing protection systems and eyewear attachable hearing protectors. In one example, an eyewear hearing protection system can include a lens portion that includes a lens to be positioned in front of an eye of a user. A head support can extend back from the lens portion. An earplug dock can be positioned or positionable on the head support. An earplug can be attractable to and dockable on the earplug dock. In another example, an eyewear attachable hearing protector can include an earplug dock including an attachment portion to attach to a head support of an eyewear, and an earplug that is attractable to and dockable on the earplug dock.

Abstract: Disclosed are laser guides for guiding a handheld laser during intra-oral photobiomodulation. The guides include a hollow end cap detachably secured over an end of the laser hand piece, with an opening larger than the laser spot size exiting the handpiece. A hollow conical frustum extends from the end cap and has a lower opening with a diameter sufficiently large so that the guide does not interfere with the laser. A lower base of the frustum may rest on a patient's tissue so as to maintain a predetermined separation distance between the laser exiting the hand piece and the patient's tissue.
