Solution Overview

Problem

Existing methods for obtaining accurate measurements of eyewear for custom modifications are prone to error and require expensive equipment, especially when capturing images from non-standardized positions, and traditional measurement methods lack portability and precision.

Innovation Solution

A portable device with alignment indicators on multiple surfaces and a bendable design, along with an angle-fixation mechanism, assists in capturing standardized images of eyewear by ensuring the camera is positioned correctly, using a mobile device to evaluate alignment and calculate measurements.

AI summary

A device is provided for obtaining an image of eyewear from a forced perspective such that measurements of the eyewear can be obtained from the image. The device includes a horizontal alignment indicator and a vertical alignment indicator that each span across two non-coplanar surfaces. When an image is captured from the proper predefined horizontal and vertical positions with respect to the device, the horizontal and vertical indicators will align across the two non-coplanar surfaces. The device can also include a distance indicator. The device can be constructed from a kit that can be easily mailed in a flat envelope. A mobile device can be configured to assist with capturing the measurement image and provide feedback to assist the user to properly position the mobile device to obtain the measurement image.
