Why does the FAA not recommend polarized lenses for pilots?
- could interfere with visibility through laminated windshield
- could reduce or eliminate visibility of LCD instruments
- could reduce or eliminate visibility of instruments with polarization based anti-glare filters
- could masks the sparkle/glare/reflection of light off shiny surfaces (another aircrafts wing)
26
Glasses for farming
Sturdy frame
Brown tinted lenses/transitions
Flat top 28
Polycarbonate or CR39
This is one situation when glass could be used
Don’t do AR coating because the dirt will destroy it

Miracles eyewear for babies
31
Reading glasses
If both eyes need the same correction, can purchase OTC readers
- could buy multiple pairs and mix and match lenses
- if each eye is differnt, custom correction can be ordered
32
Tips for face shape and frames
- try to Macy eyewear with tour best personal feature (blue eyes with blue frame)
- frame shape should contrast with your face shape
- frame size should be in scale with your face size
- eyeclolor looks best when starting in his or her own color base
33
Round face
Curved lines with same width and length
-to appear thinner and longer, look for angular, narrow eyeglasses, a clear bridge that widens eyes, frames that are wider than deeper
34
Oval face
Balanced proportions
| -frames that are wide or wider than the broadest part of the face
35
Oblong face
Longer than it is wide
-to appear shorter and more balances, look for frames with more depth than width, contrasting temples that add width to the face
36
Base-up triangle face
Wide top third, small bottom third
| -look for frames that are wider at the bottom, light colors, rimless frames
37
Base-down triangle face
Narrow forehead, widens at cheek and chin
| -to add width look for heavy accents of color and detail on the top half, cat eye shape
38
Diamond face
Narrow at the eyeline and jawline, broad cheek bones
| -look for frames with distinctive brown lines, rimless, oval, or cat eye
39
Square face
Strong jawline and broad forehead, width/length the same proportion
-look for narrow frames, oval shapes, frames with more width than depth to try to soften angles and lengthen face
40
Oversized frames
Not good on any one
41
Color of frames
Everyone looks good in his or her own color base
| -warm or cool
42
How do you determined color palette for a person
Use skin, eyes, and hair to determine color pallet
43
Skin color and frames
Blue or yellow
- if veins look green: warm
- if veins look blue: cool
44
Eyes and frame color
Many variations in eye color
| -matching eye color to the frame
45

48
How to pick a frame for a patient
A frame that goes with everything vs flattering color that makes a personal statement
49
New frame technology
- no tangle nose pads

- interchangeable lenses
50
Asian fit frames
-a type of eyewear fit designed for lower or minimal bridges and high cheekbones
51
What problems fo Asian fit glasses fix
Lifts glasses off cheekbones
Properly places glasses on nose
Prevents eyelashes from touching the lenses
52
What is the difference of Asian fit and regular fit
Thicker, elevated nose pads
Shorter and wider lens
Reduced frame curvature
Narrow bridge
53
Measuring patient for a pair of glasses
Background info
- can I look at your Rx
- what do you do for a living, what are yours hobbies?
- do you currently wear glasses
- have any issues with current eyewear
Ask Qs: open ended questions! What do you struggle with when playing golf?
54
Spends all day at a computer
Computer PAL or SV intermediate
55
Patient who likes to fish
Polarizxed lenses
56
Patient who drives for a living
Two pairs, sunglasses and clear with A/R
57
Measuring PDs monocularly
Monocularly: a separate measurement taken from the center of the patients nose to the visual axis in the right and left eye
- all jobs
- record individually
58
Binocularly PDs
Single measurement taken from the visual axis of the right eye to the visual axis of the left eye
- should only be used on multioficals
- record as one number
- mm
59
Most important thing to keep in mind when measuring PDs and heights
Body position
- you must be on the same level as your patient looking directly into his/her eye
- OC or seg height (or difficult PD), to lowest portion of the frame, not necessarily directly below the pupil
60
Measuring frame to patient
- place yourself across from the patient and at the same height
- adjust the frame so it sits correctly and is in the preferred wearing position
- dot the demo lenses directly in form of the patients pupil
- measure heaight from bottom of frame to dot
61
When to take OC height
No rule or standard
Always
Over 4.00
62
Measuring lined multi focal lenses
- consider posture/observe patient
| - where does the patient currently wear them?, does it appear high or low, textbook fit?
63
If patient wears bifocal high
Ask patient about lowering head to see over it
64
If bifocal low
Ask patient about titling head back to read
65
Occupation and lifestyle for bifocal
Sit with protein, used from they will wear, adjusted and correct size
66
Measuring PALs
Monocular PD and fitting height
Measur with pupilometer-corneal reflex
-fitting height lowest portion of the inside of the frame to the pupil center
67
Customized PALs
Special equipment for precise measurements
| -Apps
68
Means delivering glasses to a patient
Dispensing eyewear
69
Dispensing involves
```
Checking for fit
-temple bend
-alignment
-nose pads
Making any necessary adjustments
Checking vision with the new pair
Education on the lenses, care, and any add ones purchased
Microfiber cloth, case, etc
```
70
First time progressive wearer dispensed
- adaptation period
- point the nose
- look straight ahead and check the distance vision
- use a reading card to check near vision
- as patient looks up and down, reading card will go in and out of focus
71
Lined mulitfocal: dispensing
Due to magnification in the lower portion, patient must be careful when looking down
- stairs, curbs, feet
- drop the head to look through the top of the lens
