OCCUPATIONAL LENSES What is an Occupational Lens? An Occupational Lens (or Enhanced Reader) is a reading lens that has a Degression zone to incorporate the Intermediate prescription (and sometimes‚ depending on prescription‚ a good DV portion) Why dispense an Occupational Lens‚ instead of a Reading pair of glasses? With more and more people using Computers‚ Laptops and Smartphones‚ we demand more from the Intermediate zone than ever before. So by dispensing a pair of Reading glasses to a

session we had with BL we were introduced to the works of David Tripp‚ Stephen Brookfield and Donald Schon which focused on critical thinking and self-reflection in teaching and learning environment. We as a group were given Stephen Brookfield’s “four lenses” document to review. In summary Stephen Brookfield states that for a teacher to become critically reflective there are three inter-related phases that are involved: 1. Discovering the assumptions that guide our decisions‚ actions and choices 2

Executive Summary Optical fibres are being increasingly used in the telecommunications industry. They are slowly replacing the conventional copper cables due their superior ‘data transmission’ properties. They transmit data via light pulses within glass or plastic strands. Fibre optics fit the material requirements for good data transmission since they are ability to transmit and preserve quality of signals‚ durable and cost-effective. Some of the current materials employed within the industry

Compared to lenses made with CR-39 plastic or even polycarbonate‚ high index lenses are expensive. Because of their cost‚ it’s only natural that you would want to keep your high index lenses for as long as possible. Of course‚ the same is true for the frame as well. The longevity of your high index eyeglasses comes down to your selection of protective coatings for the lenses‚ your frame selection‚ and your use and care habits. Anti-Scratch Protective Coating High index lenses are made from high-refractive-index

SITUATION ANALYSIS: Optical Distortion Inc.(ODI) markets lenses that distort the vision of chickens. These lenses are used instead of debeaking. Lensed chickens are more likely to survive from cannibalism among the chickens. The lenses are also supposed to reduce the amount of feed per chicken per day than that for debeaked chickens. Using lenses do not lead to any trauma among chickens and therefore do not affect their egg laying capacity. The objective of the case is to present a financial

3M Optical Systems: Case Brief As Andy Wong‚ how would you handle the authorization for expenditure for the re-launch of the privacy screen? As Andy Wong‚ I would take the proposal to one of my senior-level mentors for support. The OS unit has already tried and failed three times with the microlouvered filter and high level support would benefit both Wong and Guehler in this case. If Guehler sees that other areas of 3M are in support of the authorization for expenditure‚ then he will not have

Optical illusions are all around us(explain). The brain remembers what it has seen before‚ then when it sees something similar it takes shortcuts when looking at a new images. This causes the brain to make mistakes and creates optical illusions. An optical illusion is a misleading image that deceives the eye. Different people see optical illusions differently because of their previous experiences. Previous experiences help the brain interpret what it sees. If your previous experiences determine

Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)
