Hateyes Magnifying Glasses
Hateyes are hat-brim mounted, clip on magnifiers for fly tying and tying knots.
Hateyes are great a great choice for when threading 6X tippet through the eye of a size 20 dry fly becomes too difficult. They are there when you need them, and can be folded back under the brim of your hat for when you are back to fishing. A super convenient and no-hassle solution to problems with close range vision.
