- 2. Frame Selection Proper frame selection is of utmost importance. The Optician must draw upon many of his-her skills to achieve a satisfactory fit and a satisfied Patient. He must know what the frame will look with lenses, and how it will perform in fulfilling the wearer’s need.
- 3. Wearer’s Old Frame Sometimes a persons wants to wear their old frame. This may or may not be appropriate. Reasons for not new include cost, comfort of old frame and cosmetic appearance.
- 4. Cosmetic Consideration • From an esthetic point of view, glasses are of no small importance to the wearer. • The wearer often needs help in frame selection. • Any new frame will represent a change and will look strange. • Frame selection is often a process of trial and error, time consuming and frequently frustating.
- 5. Frame Selection By Face A good frame selection can be simplified by considering which facial lines are complimentary to the person. Hairstyle can also alter the apparent shape of the face. A well selected frame can increase the attractiveness of the face.
- 6. Facial Types • While most faces are a combination of shapes and angles. • There are seven basic face shapes: • Oval, • Oblong, • Round, • Square, • Triangular base-down, • Triangular base-up, and • Diamond. Diamond Triangular Square Oval Oblong Round
- 7. • By considering these three main aspects and the seven face shapes that follow, the Dispenser can give Patients valuable guidance in the selection of their new eyewear. • The frame shape should contrast with the face shape. • Rounder faces look best in frames with some angles. • Angular faces look best in frames with some curves.
- 8. • The frame size should be in scale with the face size. • Frames should be selected in proportion to the face size, e.g., a petite woman with delicate features will want a smaller, lighter weight frame. • Eyewear should repeat the Patient's best features, e.g., a blue frame to match blue eyes.
- 9. Oval-Normal Face • Oval-Normal Face – • Most shapes will be suitable. • The oval face is considered to be the ideal shape because of its balanced proportions. • To keep the oval's natural balance, look for ophthalmic frames that are as wide as (or wider than) the broadest part of the face, or walnut-shaped frames that are not too deep or too narrow.
- 10. Oblong-Long Face • Oblong-Long Face – • Deep frame preferably with low temple attachment. • Frames with a lot of depth, such as aviator frames, suit oblong faces. • A low nose bridge will shorten the nose, too. • The oblong face is longer than it is wide and has a long straight cheek line, and sometimes a longish nose.
- 11. Oblong-Long Face To make the face appear shorter and more balanced, try frames that have a top-to-bottom depth, decorative or contrasting temples that add width to the face or a low bridge to shorten the nose.
- 12. Round-Wide Face • Round-Wide Face – • Relatively narrow frame preferably with a high temple attachment. • Round faces look good with angular narrow frames that lengthen the face. • A round face has curvilinear lines with the width and length in the same proportions and no angles. • To make the face appear thinner and longer, try angular narrow frames to lengthen the face, a clear bridge that widens the eyes and frames that are wider than they are deep, such as a rectangular shape.
- 13. Square-Wide Face • Square-Wide Face – • Same criteria as round face. • Needs frame that softens the face angles, such as narrow ovals. • A square face has a strong jaw line and a broad forehead, plus the width and length are in the same proportions. • To make the square face look longer and soften the angles, try narrow frame styles, frames that have more width than depth, and narrow ovals.
- 14. Triangular-Inverted Base-Up • Triangular-Inverted Base-Up • (Heart) Face – • Lighter looking frame is recommended such as metal or rimless or lighter colors in zyl. • Faces in the shape of a base-up triangle need frames that are wider at the bottom, with very light colors. • Rimless frames and semi-rimless frames are also good choices.
- 15. Triangular-Inverted Base-Up This face has a very wide top third and small bottom third. To minimize the width of the top of the face, try frames that are wider at the bottom, very light colors and materials, and rimless frame styles, which have a light, airy effect since the lenses are simply held in place at the temples with screws.
- 16. Triangular-Erect Base-Down Face Triangular-Erect Base-Down Face – Width of frame should approximately equal lower widest part of facial area. Darker colors work well. Faces in the shape of a base down triangle look great with eyeglasses, which have color accents, details on the top half of the frame.
- 17. Triangular-Erect Base-Down Face The triangular base-down face has a narrow forehead that widens at the cheek and chin areas. To add width and emphasize the narrow upper third of the face, try frames that are heavily accented with color and detailing on the top half or cat-eye shapes.
- 18. Diamond Shaped Face Diamond Shaped Face – Looks well with frames that have detailing or distinctive brow lines. Diamond-shaped faces are narrow at the eye line and jaw line, and cheekbones are often high and dramatic. This is the rarest face shape.
- 19. Diamond Shaped Face To highlight the eyes and bring out the cheekbones, try frames that have detailing or distinctive brow lines, or try rimless frames, or oval and cat-eye shapes.
- 20. Frame Color • There are three key elements in the choice of frame colors: 1. Everyone has either a cool (blue-base) coloring, or a warm (yellow-base) coloring. 2. Everyone looks best in his or her personal color base. 3. Eyewear color should complement personal coloring.
- 21. • The best frame color depends on the look the Patient is interested in creating: • light frames for fair skin, darker frames for darker tones. • Try several colors in the shade range to find the best one. • For example, if considering dark frames, try the same frame in dark blue, dark green, dark purple and black, or any other available dark color, • to see if one of those is better than the others for their skin tone.
- 22. • The main factors to determine the best color palette are the colors of the skin, eyes, and hair. • SKIN Skin tone is the prime element in determining coloring. • All complexions fall into one of two color bases - blue (cool), or yellow (warm). • A cool complexion has blue or pink undertones, and a warm complexion has a "peaches and cream" or yellow cast. • Olive skin is considered cool because it is a mixture of blue and yellow. In the United States, cool, blue-based, complexions are more common than the yellow-based, warm, complexions. • About 60 % of the population, are "cools."
- 23. • EYES Eye colors are usually a secondary element in determining coloring because of the wide range of eye colors. • Examples: Blue eyes can range from a cool, almost- violet, to a pale blue-gray, which is warm. • Brown eyes can vary from a light cider shade, warm, through a medium-brown to a cool, almost-black.
- 24. HAIR Hair colors are also considered warm or cool. Strawberry blond, platinum, blue-black, white, salt- and-pepper, and "dishwater" brown are cool. Warm hair colors include golden blond, flat black, brown-gold, "carrot" and "dirty" gray.
- 25. • Once it has been determined the Patient has "warm" or "cool" coloring, find the frame colors that will suit them best. • For warm coloring are: camel, khaki, gold, copper, peach, orange, coral, off-white, fire-engine red, warm blue and blond tortoise. • For cool coloring, the best frame hues are black, rose- brown, blue-gray, plum, pink, blue and amber (darker tortoise).
- 26. Bridge Selection Selecting the proper bridge size and shape for any given Patient is a crucial part of frame selection both from a cosmetic, and purely practical perspective. Since a “high” bridge such as a keyhole style, tends to accentuate nose length, it should be avoided with longer noses, and recommended with shorter, stubbier noses.
- 27. Bridge Selection The opposite holds true with “lower” bridge designs, such as a saddle bridge. Patients with especially narrow bridges are generally successful with adjustable nose pads. Very often adjustable pads can be added to a zyl frame, which may increase the selection of wearable frames for the narrow-bridged Patient.
- 28. Bridge Selection Saddle bridges and “comfort” bridges for metal frames are difficult to adjust, Therefore care must be taken to insure the fit is suitable, right from the beginning, during the initial frame selection.
- 29. Frame Selection and Prescription Considerations High Minus Lenses: Smaller Eye Size Heavier Frame Material Rounder Shapes Lightweight Lenses Higher Index Lens Material Antireflection Coating Lightweight Lenses Edge Coating
- 30. Fitting Consideration High Plus Lenses: Smaller Eye Size Sturdy Frame Construction Rounder Shapes Small Frame Difference Adjustable Nose Pads Lightweight Lenses Higher Index Lens Material
- 31. Fitting Consideration When presented with a prescription of higher powers: Proper frame selection is of utmost importance. The frame size must be kept to a minimum. The fit and style of the bridge takes on added importance due to additional lens weight-thickness.
- 32. Fitting Consideration The eyes should be well centered in order to minimize decentration. Usually, when the lens power exceeds ±6.00 or ±7.00 diopters, depending on the Patient, vertex distance must be considered as an important factor.
- 33. Fitting Consideration Progressive addition lenses: A minimum vertex distance An adequate pantoscopic tilt Sufficient vertical depth in the nasal portion of the frame The shape of the frame(vertical depth )
- 34. Selecting Frames for Children Sturdy frames Deeply grooved frame fronts Quality spring temples Bridges that give support in the area of the lower portion of the nosepad High impact lenses such as polycabonate or Trivex Sports protection when available
- 35. Selecting Frames for older Wearer Light weight frames Bridge must fit correctly Frame with adjustable nosepad Unconcerned with style
- 36. Selecting Frames for Safety Eyewear Safety frame is not just sturdy frame Must fulfill specific standards (Z87, Z87-2 ) Metal frames should be avoided
- 37. Fitting We say that a frame that fits well should go straight back from the chassis end to the ear. The temple should not angle in or out and should not touch the face until just before the ear. The arrows indicate what a good fit would be so you can see that this frame is much too large for this patient.
- 38. Bad fitting Notice the large gaps between the frame and her face. Notice that the temple bends in towards her head from the chassis end. These are both good indications that this frame is much too large for her.
- 39. Bad fitting Here is the perfect example of seeing beyond the fashion. Pretty frame, but not a very pretty fit. The frame is much too small or narrow and the temples are actually touching her face. If this frame size was a 52 you would probably check to see if it came in a 54
- 40. In this image the frame is too small. You can tell this by how the temples angle slightly out from the chassis end.
- 41. Here is an excellent way to tell that a frame is too small! Look closely and you can see that the spring hinge is partially open.
- 42. This is a much-exaggerated image but gives you an idea of what we mean when a frame is not level.
- 43. This is what we mean when we say a frame is level. No, it is not an attractive frame and it is not even a great fit but the square shape lets you see the concept. As mentioned you will need to decide what your reference point will be to level a frame, eyebrows or eyes.
- 44. Good fit This is what we want to see when we look for nose-pad to nose contact. Look closely and you will see no sharp angles, no shadows, and the frame is well positioned on her nose
- 45. This image is slightly exaggerated but is still useful to get an idea about nose pad angles. Obviously, the pad on the left will need to be adjusted to meet the shape of the patient’s nose.
- 46. Take a close look at the fit on these pads. At a glance, they look good but if you look closely (look for the shadow), you will see that they are actually angled away from the top of her nose and would need to be adjusted just a little.
- 47. This frame may not be this patient’s first choice for fashion but it does show a great fit. Notice the way the frame matches the shape of her nose. It makes full contact for the entire bridge, along each eyewire and good contact with the molded nose pads, which can be seen behind the frame.
- 48. Here is another example of a good fit. The frame sits well in relationship to her eyes, and the frame makes good consistent contact with her nose.
- 49. This is what we never want to see when fitting a plastic frame. This is a keyhole bridge and they will only fit certain nose types. Notice how the frame only makes contact with the nose at two points and those two points are actually sharp edges! You can imagine this patient will be uncomfortable after wearing the glasses for a very short time.
- 50. This is another example of what you do not want to see. This frame is only resting on two small contact areas and you can see the gap along the top. You never want to see gaps or spaces.
- 51. This temple bend is too early since it is starting to bend before it reaches the ear. Notice what that early bend makes the frame do! It pushes it up, forces unwanted tilt, and actually pushes the frame down her nose.
- 52. This is what we mean when we talk about vertex depth imbalance. It is usually caused by poor temple open angles or by a temple bend that is too tight.
