Factors to be considered while choosing surgical loupes-

Some of factors that play a major role in selecting perfect surgical loupes include resolution, working distance, field of view, depth of field, magnification, weight and inter-pupilary distance.

Let us know about all these in detail, as a general rule, lower the magnification, greater is the depth of field and field of vision. Similarly, longer the working distance, more is the field of view. Also the larger is the field of view; there will be less chances of making your heads turn. Generally surgeons prefer for light weight lopues, they are the best option when required to work for longer hours.

There are three styles of head loupe available; first one is the single lens loupes that are for low-magnification applications. Second type is the Galilean loupe designed; it makes use multiple lenses and a magnification of 2.0x and 3.0x. For more magnification you can use about 8.0x, prismatic loupes, designed by Johannes Kepler. These loupes use a series of lenses and prisms to magnify the subject and offer greater magnification, sharp resolution and high depth of field.

Considering facts-

• Working distance- It is defined as the distance at which the loupe will focus, distance should be from the loupe lens to the top of your subject. Every loupe has a particular defined distance but it depends on your height, posture and working position.
• Resolution of the Loupe- Resolution is determined by the amount of fine details that are distinguished. Type of glass used in the lens coating affects the resolution of your loupe. Loupes with a high resolution will have crisp, straight lines while lines that appear slightly blurred and curved are viewed with lower quality lens.
• Depth of Field- It is directly related to the working distance and magnification factor. Depth of field is the amount of depth that is in focus while viewing the subject thought the loupe. Generally greater depth of field is, the better it is, you are able to see deeper into the subject without repositioning it. To get a high depth of field select a loupe that has a longer working distance or a lower magnification feature.
• Inter-pupilary distance- It is the distance between pupils of your two eyes, for the sake of comfort loupes should fit into eyes
