TOOLS

Pupilometer

START

A pupilometer is a tool used to measure the distance between your pupils. This measurement can be taken in a plethora of ways including Mono and Bino, 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

Neutralization

START

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

Neutralizing

OLD SCHOOL LENSES

START

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 LOLCLICK 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 ExecutiveTrifocals 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?

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

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 meansTopics 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

PRISM

START

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

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

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?

Marie explains that she needs to tilt her head down to see through her distance portion of her progressives. What is the problem?

Marie Needs Help!

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

Pupilometer 101

This picture is similar to what it looks like on the test

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!!!

Josh explains that he needs to tilt his head up to see through his distance portion of her progressives. What is the problem?

Doug explains that he feels like he is walking downhill, what type of prism is he experiencing?

Doug Needs Help!

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 twoExample: 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 +5.00The add would be a +2.00 because the distance from +3.00 to +5.00 is +2.00

BIFOCAL

Lea explains that she feels as if she is standing in a bowl, or walking uphill, what type of prism is she experiencing?

Lea Needs Help!

KEEP IN MIND, WHEN YOU ENTER THE PRESCRIPTION, MAKE SURE TO PUT ZEROS!!!Example: -2.00 -0.50x090

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.
