Choosing loupes is choosing how your spine ages. Prioritise, in order:
- Declination angle (ergonomics) — #1 for neck/back longevity. iLoupes is built on a 60° geometry.
- Magnification range & adjustable working distance — buy a platform that grows with your work.
- Published optics — insist on real data (MTF, resolution), not adjectives.
- Weight — lighter reduces fatigue.
- Fit & trial — buy from someone who fits locally and lets you trial risk-free.
