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.

1. Loupes with an improved declination angle, comprising:
eyeglass frames with carrier lenses, each carrier lens having a lower edge; a hole formed in each carrier lens, each hole defining an outer edge that intersects with the lower edge of its respective carrier lenses, such that each carrier lens has a gap devoid of lens material between opposing spaced apart points of lens material oriented toward one another; a pair of loupes, each having a body cemented in a respective one of the holes, such that a portion of each loupe also extends below the bottom edge of its respective carrier lens; and wherein each loupe is cemented in position to achieve a desired declination angle.
