Review on 🔬 Aries Outlets 3.5x 420mm Working Distance Surgical Binocular Loupes with LED Head Light Lamp+Aluminum Box - Black (Optical Glass) by Heidi Smith

. At around $50 this is a great Magnifying Glass and Light combo. This is in no way comparable to my Surgitel TTL loupe or Designs for Vision headlamp and I couldn't use them every day; It's a great backup pair, though, and better than nothing. Also of note is that the working distance is slightly shorter than the advertised 420mm (16.5 inches). I would say it could be 12 inches which is not conducive to good ergonomics.
