PROBLEM TO BE SOLVED: To provide a measuring apparatus for glasses which enables the accurate measurement of a distance between right and left pupils and the height of eyepoints by enabling the stable mounting of it on the frames of glasses along with excellent handlability.WARNTJES HANS...
Apparatus for measuring the factors necessary for adapting optical glasses to a frameThis apparatus, for measuring in particular the pupillary distance and the height of the optical centres on frames, comprises in combination a sensor 1 ...

A poorly fitting pair of glasses can not only feel uncomfortable, but also fail to provide proper protection from harmful UV rays. That's why measuring your face correctly before purchasing a new pair of frames is crucial. In this blog post, we'll guide you through the simple steps of mea...
Therefore, we would tend to recommend smaller, more delicate frames to complement this. However, as long as the measurements are correct and they fit, there will be less of a chance that your face is overrun by large frames. Ideal Frames For Small Heads Browline Glasses Monocle Pince-Nez ...
BIN-2.5 2.5x Viewing Binoculars Worn like glasses, thus leaving the hands free. Each side can be individually focused to meet the needs of each eye and include inter-pupillary (IPD) and nose bridge adjustments. Constructed of high quality glass optics and metal alloy lens frames. Comes in ...
For example, crystal nucleation is difficult or impossible for more polydisperse samples22,23. The crystal–liquid phase boundary depends on the polydispersity24. The sensitivity to volume fraction near the glass transition depends on the composition in nontrivial ways25,26. Experimentally, the ...

Since its founding in 2012,OneDollarGlasseshas been dedicated to solving this problem: Starting with the construction of a simple bending machine for eyeglass frames by founder Martin Aufmuth, the association has grown to more than 280 employees in currently 10 program countries, 35 permanent employ...
2. The shape measuring apparatus for eyeglasses according to claim 1, wherein the eyeglass element is a pair of lens frames comprising an eyeglass frame, and the measuring element traces respectively each groove portion which is formed inside of each lens frame, so that an inner circumferential...
There are certain lens frames which are narrow in rim width in a direction perpendicular to an optical axis of a lens of glasses and are therefore easily deformed under the action of an external force. There is a known lens frame for half glasses (called “Kanime lenses” in Japanese) who...
