LTB stands for:

The correct interpretation of LTB in the context of ophthalmic dispensing is "Location of temple bend." This term refers to the specific area on the eyewear frame where the temple (the arm of the glasses that rests on the ear) bends. Understanding the location of the temple bend is crucial for proper fitting and comfort of eyeglasses, as it directly affects how the frames sit on an individual's face and their overall alignment with the eyes.

In this field, the term is significant for ensuring that lenses are properly aligned and for providing adequate support and comfort for the wearer. A precise location of the temple bend can improve the fit of the glasses, enhancing both aesthetics and function. Proper training in identifying the temple bend location is essential for professionals in ophthalmic dispensing to ensure they meet the prescriber’s specifications and the patient's needs effectively.
