Mini Loupes are designed to be ultra light and comfortable.
Standard Loupes : larger field of view and a two lens system
Hi-resolution Loupes : bright image and larger field of view.
Prismatic Loupes : higher magnification and field of view.
Frames need to be suitable for the loupe.
Wrap frames properly designed are often used,with safety shields.
Powered caps will allow even more magnification but will change working distances.
The correct posture, viewing angle and ability to see normally are the benefits of ‘flip up’ loupes as a three way adjustable hinge allows positioning as required.
