Decentration and Blocking - 3 Examples

Описание: This week we continue our series on finishing layout work. All finishing work is based on lens movement within the frame eyewire opening. The most common movement is aligning the lens OC with the customer PD. We do this by decentering the lens. In this lesson we work through three examples of calculating decentration for simple binocular PDs and show how that e applied in a manual blocker. Optician training includes calculating lens shift for OC placement. Just as we did for our series on prism, finishing layout work will be covered in small, incremental “baby-steps” so students can easily build on prior knowledge.

Laramy-K Optical is a digital uncut and coating lab unlike any other. The only exclusively uncut lab in the country; we provide our customers with independent, high-end alternatives to corporate brands. Through craftsmanship, technology, and independent, innovative vendors like Younger, IOT, A&R, and Quantum Innovations we offer our customers the Integrity portfolio of freeform lenses and coatings. Made in the USA, the Integrity brand is not a generic house-brand, but is the absolute best available, designed to give the wearer that “wow!” experience.

In addition to the digital line, we still offer conventional surfacing, including glass. Maintaining traditional equipment gives our customers vastly more flexibility in their dispensing, particularly when it comes to more difficult prescriptions.
