How to Choose Your Magnification Loupes – Part II

This blog post is an continuation of our previous post.

Test the working distance
The working distance refers to the distance between your eyes, and the patient’s mouth. You can measure this while assuming your normal working position, making sure you are: comfortable, that your back is straight, and that you are not leaning forward too much.

Perhaps you could ask someone to assist you in this procedure. You can also use the following overview to help determine the best working distance for your personal needs:

Height:
<170 cm (5ft 7 in) 170-190 cm (5ft 7 in to 6ft 4 in) >190 cm (6ft 4 in)

Sitting:
340 mm (14 in) 420 mm (16 in) 500 mm (20 in)

Standing:
420 mm (16 in) 500 mm (20 in) 550 mm (22in)

Check the field of view.
The field of view is the area that is visible and in focus, while looking through the loupes. A larger field of view is preferred, as there is a larger area visible through the loupes, and there is less need to move your head around . The size of the “field of view” also corresponds directly to the magnification factor.

A loupe with a lower magnification factor will have a larger field of view, and vice versa. All loupes utilize high performance lens systems that provide an extra wide field of view (up to 125mm / 4.9 inch).

Check the depth of view.
The depth of field is the depth of the area that is visible as well as  in-focus, while looking through the loupes. A larger depth of field is preferred, as there is a deeper area visible through the loupes. The size of the “depth of field” corresponds directly to the “working distance”.

A loupe with a longer working distance, will have a larger depth of field, and vice versa. The size of the “depth of field” also corresponds directly to the magnification factor.

A loupe with a lower magnification factor, will have a larger depth of field, and vice versa. All loupes utilize high performance lens systems that provide an extra large depth of field (up to 120mm / 4.7 inch).

Test the weight of the loupes.
Weight is an important factor when choosing a new loupe, especially if the loupe is to be used for longer periods of time. Lightweight loupes are more comfortable, and in the long term, will reduce tension and other complications. Ultra light weight loupes, offer the maximal comfort. All loupes utilize extremely light weight materials.

Regarding the Keperlilean loupes, these loupes are heavy. When choosing these, opt for the headband style, which will be comfortable for using a long time.

Three Easy Steps for Choosing Your Surgical or Dental Loupes

Step 1

As a surgeon, dentist, veterinarian or other medical professional, you need first to decide what the appropriate level of magnification is best suited for your work. A higher magnification will limit the depth of field to some extent.

There are three magnification levels:

2.5x which enlarges the focal object approximately 2.5 fold.
This is the common standard for dental professionals. It is recommended for
first time loupe users, since it gives the widest field of view.
This magnification allows for viewing the entire work area (e.g., the entire mouth) at close range.

3.0x which enlarges the focal object approximately 3 fold.
This level of magnification is especially suitable for those professionals whose work requires a more detailed view.
This magnification is popular with experienced professionals who are accustomed to transitioning from magnified to non-magnified vision.

3.5x which enlarges the focal object approximately 3.5 fold.
This is the highest magnification rate available. It is typically used by professionals when performing surgical procedures.
Since it provides a highly focused field of view, it is not recommended for all-day use.

Step 2

The next step is finding the right working distance. To determine the optimal working distance, you as the wearer must measure the distance between the tip of your nose and the focal object.
There are four available options: 340mm; 420mm; 500mm; 550mm.

Step 3

Finally, you need to select the frame that suits you best in color and style.
AdmetecVision offers two types of frames, both available in a wide variety of colors.
The UltraLight frames are light in weight and most appropriate for users who want to wear the loupes throughout the day. It is also the preferred option for those professionals who suffer from back pain or stiffness.
