These technical steps will help you to determine the right fit for your frame.

Five components are required for a technical fit:

1) The shape of your face

2) Frame width

3) Size and style of the bridge;

4) Temple length

5) Lifestyle.

Each component plays an important role in choosing the right frame for you customer.

The Five Essential Components of a Technical Frame:

1). Face Shape – Every person has a different face shape. This is why there are so many styles and types of frames. It is important to choose a frame that suits the customer’s style and enhances their overall appearance. It is subjective to choose a frame for a customer based on their face shape. What may be appropriate may not be what the customer desires. Here is a chart to help you identify the right style frame for your face based on the shape of your face.

Oval face – Normal shape – All shapes are suitable

Oblong face – Long shape – Deep frame, preferably with low temples

Round face – Large shape – Preferably with a high temple.

Square face – Wide form – The same criteria as for a round face

Triangular face – Erect triangle shape. The width of the frame should equal the lower part of the facial area.

Diamond face – Inverted Triangle shape – Lighter frame (metal, rimless).

2). Frame Width – This technical dimension matches the frame width to the customer’s face. The frame’s front should be large enough to allow for a straight line from the end to the ear. A frame that is too narrow or too wide can cause discomfort for the customer and may affect the frame’s ability to adjust. The position of your eye within the frame will tell you if it is too wide or too narrow.

to Wide: A frame that is too large for a person’s eyes will cause their eye position to be close the bridge. This will cause the customer to appear cross-eyed, and the temple side will have a lot of lens material. This type of fit may work for products with an over-sized appearance (e.g. Clear lens designs are not recommended.

To Narrow: A frame that is too small for a person’s face will give you two indicators. The eye position will be towards temple side, while the temples will touch the temples. This will create a “squeezed look” on the face. It is important to determine the eye size of the frame so that you can avoid frames with a smaller eye.

Just right: If your frame width is correct, your eye will be in the center of it and will create a direct path to the temple from the frame front towards the ear. If your eye position is not perfectly centered, it’s best to have the eyes slightly inward toward the bridge and not towards the temple. If a customer has a narrow pupillary (PD), you should first examine the position of their eyes in the lens to determine if adjustments to the temples could reduce or eliminate any squeezing.

3). The Style and Size of the Bridge- After you have established a width that is suitable for your customer; it’s time to think about the style and size of the bridge. The bridge holds 90% of the lens and frame weight. This is an important section. A good fit in the bridge will ensure a comfortable fit.

A good bridge fit will be determined by how much surface is flush with the nose. The more surface of the bridge rests on the nose, the more comfortable it will feel. If the bridge is too close to the nose or the weight is distributed less evenly, the frame will feel uncomfortable. This can cause pain and irritation. There are many ways to alter the fit of a bridge but there is no substitute for a well-fitting bridge.

4). Temple Length – Now that you have an understanding of how the frames rest upon your face, it is time to understand how they hold themselves in place. While the bridge can support 90% of the frames’ weight, temples will likely need to adjust 90%. When discussing comfort and fit, temples that fit well should be considered. A bridge that fits well will fit most patients’ noses with minimal adjustment. However, a pair of temples that fit perfectly will require some custom adjustments to each individual.

A proper temple fit is similar to a perfect bridge fit. It involves placing as much temple surface as possible over the largest area. The temple weight should be evenly distributed between the temple’s back and the front of the frame when fitting a frame. A temple’s holding power is concentrated on a small area, which can cause discomfort in the frame.

The location of the temple bend is another key indicator of temple length. The proper temple bend should begin at the top of the ear, where the skull and ear connect.

If the temple is too short, the temple bend will begin before the base of your ear. This puts maximum pressure on the backside. If a temple seems too small for the customer it is best to choose a shorter temple (if possible) or a different frame. It will take time to adjust a temple that is too small and will result in a customer who feels uncomfortable.

A temple that is too long will cause the temple to bend after the base of your ear. This can make the temple appear loose and unstable. If a temple is too long for the wearer, it may be adjusted to fit the temple properly to their skull. It would be better to have more frame material than less if you had to make a decision between a temple that is too long or too small.

5). Lifestyle – Ask the customer how they plan to use their new frames. You can then direct the customer to choose the right frame that will allow them to use the product in a way that is safe for the product and the customer. Asking questions about your customer’s hobbies, interests and work can help you to do this. We don’t want to sell products that are too small or too heavy for the needs of each customer. You will be able to select the right frame for your customer if you have as much information as possible from them about the intended use of the product.
