What is it used for?Bringing temple arms up and down
Allows you to change the axis of a lens Holds the lens so that you can adjust the frame
Three piece mounting, specifically for the notches where the temple is holding the lens
Holding the temple without damging the frame
THESE ARE NOT ALL OF THE TOOLS, JUST THE MAIN ONES!!!!!!!!!!!
Pupilometer
START
Pupilometer
A pupilometer is a tool used to measure the distance between your pupils. This measurement can be taken in a plethora of ways including Monocular and Binocular, and distance, intermediate and near depending on what the questiion is asking for. MAKE SURE YOU READ AND UNDERSTAND WHAT THE QUESTION IS ASKING YOU FOR AND ONLY ANSWER WHAT THEY ARE ASKING FOR!!!!
Neutralization
START
Neutralizing
Assuming that you know how to neutralize, All that you need to keep in mind is the way you put in your answer and also keep in mind that some of the answers will be in .12 as well... more info here

BIFOCALS
Bifocals are eyeglasses designed to correct vision at two different distances. They are typically used for people with presbyopia (age-related farsightedness) and another refractive error, such as myopia (nearsightedness) or hyperopia (farsightedness). Traditional bifocals have a visible line separating the two segments, and there are several different types, such as flat-top 25, flat-top 28, flat-top 35, and Executive, which go across the entire lens. Search it up if you aren't familiar with how they look, I don't have space for pictures LOL CLICK THE BIG ICON FOR THE IMPORTANT INFO
Neutralizing
Trifocals
Trifocals are eyeglasses designed to correct vision at three different distances: near, intermediate, and far. They are commonly used by people with presbyopia (age-related difficulty focusing on close objects) who also need correction for distance and intermediate vision, such as for computer use or reading. Similar to the bifocal, the trifocal also has several types, 7x25, 7x28, 8x35 and Executive Trifocals are fit at the lower pupil!!! To find the add power of a trifocal it is the same as a bifocal, dont even worry about the intermediate portion of the trifocal
PRACTICE
If you are neutralizing a pair of bifocals and your distance spherical is a +6.00 and your reading seg is a +9.75, what is the ADD power? If you are neutralizng a pair of bifocals and your distance spherical is a -3.00 and your reading seg is a +1.00, what is the ADD power?
PRACTICE
If you are neutralizing a pair of bifocals and your distance spherical is a -3.12 and your reading seg is a +2.37, what is the ADD power? If you are neutralizng a pair of bifocals and your distance spherical is a -9.00 and your reading seg is a -5.00, what is the ADD power?

PRISM in Lensometer
START
PRISM
Lenses are made up of two prism either base to base (Plus Lens) or Apex to Apex (Minus Lens) In some cases, the prism can be wanted or unwanted. Using the lensometer, you need to be able to read and identify the unwanted prism within the lens and in what direction it is moving
This is how the reticle will look on the practical and it will place the miers in a specific place and you need to find out how much prism and where it is located, whether it is base up, base down, base in or base out
PRISM Question #1
How much prism is in the Right lens and what is the base direction? Disclaimer, it wont be a red dot, it will be the sphere and cyl lines that will tell you how much prism and the prism direction.
PRISM Question #2
How much prism is in the Left lens and what is the base direction?
PRISM Question #3
How much prism is in the Left lens and what is the base direction?
PRISM Question #4
How much prism is in the Right lens and what is the base direction?
PRISM Question #5
How much prism is in the Left lens and what is the base direction?
PRISM Question #6
How much prism is in the Right lens and what is the base direction?
Overall, these questions are basically the most "difficult questions" Other than that, everything else we should know which include... - Neutralizing - Tools and what they are used for - Patient trouble shooting and what it means Topics that we should focus on and perfect include... - Prentice Rule - Finding the ADD on bifocals and trifocals - Prism and how to read it on a lensomter which I will add in soon to this presentation and also Prism Direction on a lensometer - Neutralizing with those weird in between numbers (.12, .37, .62, .88) - TRYING TO NOT MAKE SILLY MISTAKES!!! - Most of this practical is simple, its just tiny mistakes that we make. We need to prevent those tiny mistakes because those mistakes are automatic zeros
This presentation is not done. I highly suggest using the ABO website to practice because it is the exact same format. This presentation is strictly a very quick crash course going over the main points and informing you on things that they do not tell you. PLEASEEEEEE FEEL FREE TO CONTACT ME ANYTIME ON ANY QUESTIONS AND IF YOU NEED FURTHER EXPLANATIONS ON ANYTHING PRACTICAL RELATED. THE PRESENTATION WILL BE DONE BEFORE CHRISTMAS
Lorem ipsum dolor
Consectetur adipiscing elit
If the question is asking you for horizontal prism and it is at 90, you would use 100% of the cyl and add it to the sphere and multiply
Lorem ipsum dolor sit
Marie Needs Help!
Marie explains that she needs to tilt her head down to see through her distance portion of her progressives. What is the problem?
Pupilometer 101
To properly measure a pupilometer reading, first you need to understand what the question is asking whether its mono or bino (one eye or two) and if the question is asking for distance, intermediate or near. Next you line up the thin bar line with the white reflex in the person's eye and once you do this, press to see the recroding and type it in
TOOLS
For the tool questions, they will give you a picture of multiple different tools lined up next to each other in a 4x3 format and the question will ask, " What tool is used to... DISCLAIMER: THE PICTURES ARE REALLY BAD QUALITY!!!
This picture is similar to what it looks like on the test
Josh Needs Help!
Josh explains that he needs to tilt his head up to see through his distance portion of her progressives. What is the problem?
Doug Needs Help!
Doug explains that he feels like he is walking downhill, what type of prism is he experiencing?
BIFOCAL
Bifocals are fitted at the LOWER LID!!!When Neutralizing a pair of bifocals and you want to find the Add power of the segment, first, you find the spherical power of the actual glasses and then you find the spherical power of the segment and calculate the distance apart from the two Example: Lets say your spherical power of the distance portion of the lens is a +3.00 and the sperical power of the reading segment is a +5.00 The add would be a +2.00 because the distance from +3.00 to +5.00 is +2.00
Lea Needs Help!
Lea explains that she feels as if she is standing in a bowl, or walking uphill, what type of prism is she experiencing?
Neutralizing
The question will ask you to neutralize and find the prescription and it may land on a number such as .12, .37, .62, .88 which are numbers in between the .25, .50, and .75, therefore it will be .12, .25, .37, .50, .62, .75, .88, 1.00 plus or minus of course.
KEEP IN MIND, WHEN YOU ENTER THE PRESCRIPTION, MAKE SURE TO PUT ZEROS!!! Example: -2.00 -0.50x090
