METHOD AND APPARATUS FOR REFRACTION AND VISION MEASUREMENT
Consumer products such as refraction measurement devices may be used for obtaining refraction measurements allow consumers to track their vision without visiting an optometrist or ophthalmologist. Such consumer products may work in concert with smart phones or other products having a touch screens that present images to refraction measurement devices. Smart phones may have resolution rates, sometimes measured as PPI or pixels per inch that are unknown to the user and/or refraction measurement device. On aspect of the invention is to provide an optical interface for the user to manually match the view port boundary of the smartphone to comport with the view port boundary of the refraction measurement device. Another aspect of the invention is the use of pre-distortion in images presented to the user. By noting the corrective movements exerted by the user upon the refractive measurement device, the user's own refractive error can be derived.

In an embodiment, multiple conjugate planes are used to create a plurality of optical pupil planes and a plurality of image planes. These optical planes solve multiple problems and introduce significant performance enhancements in the system. In one implementation of a disclosed embodiment, the measurement channel is based on the reverse Shack-Hartmann principle. By introducing a relay system (for example a 4-f lens system) the slit plane could be made conjugate to the measured system pupil plane (unlike a previous implementation where the slits were places away from the pupil plane as it was not accessible directly). Creating a virtual pupil plane allows for more accurate placement of the plane without the need for contact with the measured optical system.

Refraction Measurement of the Human Eye with a Reverse Wavefront Sensor
A wavefront sensor measures the phase distribution of a beam of light perpendicular to its axis of propagation. The Shack-Hartmann (S-H) wavefront sensor is based on segmentation of the incident light beam into small, spatially distributed, parts. Each of these parts is then incident on a lens, and the deviation of the focal spot from the lens optical axis is measured in two dimensions, usually by a camera or detector array. An array of lenses is used to characterize the wavefront of the entire beam.

Calibration and image procession methods and systems for obtaining accurate pupillary distance measurements
Accurate measurement of pupillary distance, PD, is necessary to make prescription eye glasses as well as configuring VR headsets, and using other binocular optical devices. Today, many people are ordering eyeglasses on line and obtaining their PD is often problematic for a number of reasons as the prior art fails to provide consumer friendly PD measurement systems. A disclosed eyeglass frame system comprises reference marks of known locations upon the frames. A smart phone may be used to locate the consumer's pupils, while the consumer is wearing the frames. The consumer's pupils may be marked or tagged upon a digital image of the consumer wearing the frames. By use of angles in the sight lines of the camera lens and other variable values and the known relative distances of the frame markings, a consumer's pupillary distance can be quickly and accurately derived.
