THROUGH-THE-LENS (TTL) LOUPES WITH IMPROVED DECLINATION ANGLE
摘要:
Dental/medical/surgical loupes have an improved declination angle to reduce neck and back strain. Eyeglass frames are provided with carrier lenses having bottom edges. A hole is provided in each carrier lens, each hole having an outer periphery that extends below the bottom edge of the carrier lens, resulting in a pair of opposing pointed ends. A pair of ocular devices are cemented in a respective one of the holes, such that a portion of the ocular body also extends below the bottom edge of the carrier lens. Each ocular is then cemented or otherwise permanently affixed into position to achieve a desired declination angle. For added stability, a pair of holes may be formed into the body of each ocular, each pair of holes being physically aligned with the two opposing pointed ends of the carrier lens associated with that ocular.
