GenericAist Optics Adjustable Trial Lens Frame Optometric Universal Optical Trial Frame, 50g Ultralight Optometry Test Lens Titanium Optical Test Eyepiece, AS Show, AS Show

These frames are nicely crafted and extremely light weight. 38mm lenses fit perfectly.

So I had my doubts because it had no reviews when I ordered it. Then I saw one positive review and I was at peace knowing I was receiving a high quality product. This is why oI'm posting a review of my purchase and experience with the product. Now that I have it and put it tothe test I am extremely happy with the purchase. This is by far the best mount test. The packaging was great, it arrived on time, the lenses fit like a glove, it's a pleasure to use them for subjective refraction. You won't regret it. It's worth every penny. Solid built. Lightweight. Comfortable.

Es tan liviana que al colocar los lentes se va a un lado. Es decir no se sostiene bien en las orejas del paciente. Y para colocar los lentes estorba mucho la perilla de arriba (con la que se ajusta la DP)

Sturdy, light and comfortable .

Llego en excelentes condiciones y muy fácil de usar

Very light and comfortable

Solid frame, good adjustments and fairly comfortable, slightly heavier than frames with less adjustments but light compared to similar frames.

Up to now, does excellent, way better then the traditional one. I'm an optometrist.
