Good magnification is also ergonomic.
The magnification set up I use allows me to have a straight back while working, and nothing is hovering over the client’s head making sneezing safe for all. More powerful magnification is possible without resting anything against the client’s face if one is not simply buying a higher diopter magnifying glass.
Regardless of vision of the practitioner it is a simple point that the closer insertion becomes to driving your car into a garage, the less proper insertion is a factor in level of treatment provided.
No matter what set up one uses, one needs good lighting and must be able to see what one is attempting to insert. When one is guessing on the insertion one is giving less than the highest possible care. With all the factors of treatment that are out of the electrologist’s control, we should be doing our best to maximize our use of those things that are in our control. A more accurate insertion is a more comfortable and more effective insertion.
Can an electrologist see a hair through a 3 diopter lens? Sure, a magnification of two times life size is enough to see a hair, after all, you can see most hairs without any magnification. Can you see the natural empty space in a follicle through a simple circle lamp magnification unit? Of course not. Magnification lenses for circle lamps are only two times life size (3 diopter) three times life size (5 diopter) and five and a half times life size (10 diopter). Each of these lenses require one to lower the circle lamp closer and closer to the skin one is working on. The focal distance on a ten diopter lens doesn’t even allow enough room for one to flip a tweezers when using one handed technique. If it is a circle lamp, this means the heat of the circle light is getting warmer and warmer on the skin as the focal distance lessens in relation to the higher diopter of the lens. Circle lamps also have a small “sweet spot” where vision is undistorted, and this gives poor depth perception and adds to electrologist’s eye strain. This is why loupes and scopes are better when they bring together high magnification with a long focal distance, and a bright cool light source focused on the client’s skin.
